Story

Sentinel’s new heating system filter – Eliminator – is doing the business for installers across the UK but one of the hot spots of activity is Northern Ireland, traditionally one of Sentinel’s strongholds in the water treatment marketplace going back more than twenty years.

S P Plumbing & Heating Specialists are based in Carryduff in South Belfast and operate across the Province. Established in 1997, boss Sean McGeough has been in the heating business for more than twenty five years and has been a ‘Sentinel man’ for all that time. He takes immense pride in providing outstanding customer service and has been rewarded in recent years by picking up and Achievement Award in 2011 from Phoenix Natural Gas and a Highly Commended in the Installer of the Year Award at the Northern Ireland Plumbing & Heating Awards ceremony in 2012.

“Our main objective is to continue to get accolades from our customers,” says Sean, “for providing the highest quality of work we can provide on every completed job we do. It’s all about providing high levels of customer satisfaction because so much of our work comes from recommendation.”

So it will come as no surprise that Sean sees the contribution made by Sentinel to his business as key: “We recognise that we need to provide our customers with quality products at every level of the work we do,” he says. “We work closely with Worcester Bosch because we know the quality of their boilers and we work with Sentinel because we know that using quality water treatment is vital to make sure that the heating systems we install keep working at optimum efficiency levels. A clean heating system is an efficient heating system. Plus Worcester Bosch recommends Sentinel products are used with their products by name in their installation instructions, as do most boiler manufacturers – so when boiler manufacturers have faith in a product delivering with their products, that pretty much seals the deal for me!”

Talking to Sean about Sentinel products, it clear he has faith in the quality of the products and can’t see any reason to move away from them: “I’ve never understood the logic of buying anything because it’s cheap. I tend to believe that in all things you get what you pay for and water treatment isn’t the most expensive element of a heating system installation – maybe 1-2% of the final bill. So why skimp on it and use anything but the best?”

The recent launch of the new Sentinel Eliminator system filter was a case in point for Sean. He had been fitting filters to most installations but when the new Eliminator came long he had no hesitation in giving it a go: “Why wouldn’t I? It had Sentinel’s name on it so I had faith it would do the business! And we’ve now fitted something like 100 of them and had no problems at all. They do what they say they will do and importantly we get no leaks from them which has been an issue with some other filters we’ve been asked to fit on some contracts we’ve been involved on. Eliminator is simple to fit, it’s very flexible, so easy to fit in tight spaces and whilst most customers trust us to put in the best, those that have questioned what the filter is and what it does have quickly understood the concept of cyclone technology and welcomed anything that will help reduce their heating bills and provide reliability – which at the end of the day is what everyone wants from their heating and hot water system – they want hot water when they turn the taps and heat when they turn up the room thermostat! It’s not something most people want to get into the nitty gritty of – they just want it to work and hopefully cost as little as possible in the process!”

Northern Ireland continues to be a great supporter of Sentinel and its products – the traditional chemical water treatment products from its X range and the newer products in its portfolio too. And its top end installers like Sean and his team that continue to give Sentinel a good name, from quality installations and a belief in providing the very best for their customers. To see more about Sean and S P Plumbing and Heating Specialists, visit www.spplumbingheating.com.

And if that was not enough there’s another Belfast-based heating engineer that is impressed with what Eliminator has to offer! George Nelson Plumbing & Heating – based in Belfast – has been a loyal Sentinel installer for more than 15 years! As with many companies in the sector, George himself, was raised through the ranks using Sentinel X100 and X400, more recently X800 and several other Sentinel water treatment products because he was always told to use quality products to keep heating systems running smoothly – and importantly to ensure there were no call backs to fix faulty systems after the installation work was completed.

“That was pretty much it,” agrees George. “When you use a good quality product for many years and it doesn’t let you down, you stick with it. The cost of water treatment isn’t exactly outrageous, so why save five or six pounds on inferior water treatment when you may get yourself problems from doing so. It doesn’t make sense to me. All the boiler manufacturers I respect say use a good quality water treatment product and mention Sentinel by name. They know what they’re doing and hat will keep their boilers operating efficiently – and I agree with them!”

So when Sentinel launched its exciting new technology Eliminator system filter in 2012, with quadra-cyclone technology to remove all the magnetic and non-magnetic debris from a system, George was one of the first into his local merchant branch to give it a go.

“It’s got the Sentinel name on it and I spoke to John Lynch at Sentinel who I’ve known for several years and asked him what was special about the Eliminator. He took me through it and showed me one and I decided to give it a go. That was more than fifty Eliminators ago,” says George. “And frankly I wouldn’t use any other filter now. It does exactly what it says on the tin! It removes all the circulating debris left in the system after correctly flushing and inhibiting a system. They’re easy to fit – they don’t leak – and I’ve had no call backs to any installation where I’ve used one. That’s good enough for me!”

There’s lots of useful information on the new Eliminator on the Sentinel website at www.sentinel-solutions.net where there’s a video you can watch, and you can find out more about George Nelson Plumbing and Heating by calling them on 028 9050 2800.

With the launch of the new TM1700 range of circuit breaker analysers from Megger, users with regular circuit breaker testing requirements no longer have to choose between low-end instruments designed only for simple applications and versatile but costly high-end instruments.

• Provides reliable and accurate test results in noisy high voltage substations
• Four standard models. Full stand-alone functionality or data acquisition models without user interface.
• Fast and safer with DualGround™ testing, both sides of breaker grounded
• On-screen assistance with connection diagrams and test template Wizard
• All models can be controlled via computer

Dual-ground safety

Drawing on its wide experience of circuit breaker testing, Megger has developed TM1700 instruments to offer the most useful and widely used features of high-end analysers at a very attractive price. The technology used in the new instruments is based on Megger’s popular and proven high-end TM1800 series, which remains the most attractive option for users who need the ultimate in circuit breaker testing flexibility.

Among the many key features inherited by the new TM1700 range of instruments is DualGround testing, which means that tests can be performed with both sides of the breaker grounded. This greatly increases operator safety by eliminating the risk of high voltages being induced into the breaker under test.

Incorporates active interference suppression

TM1700 instruments also incorporate active interference suppression, which means that they consistently deliver accurate and dependable results, including measurements of PIR values, even in electrically noisy environments such as electricity substations. A further important benefit is that all inputs and outputs are galvanically isolated, making it possible to perform all relevant measurements in one test without the need to change connections.

Range of four instruments to match your requirements

The new instruments are available in four versions, allowing users to choose the specification that best matches their requirements as well as between standalone and PC-controlled units. Standalone models incorporate a large colour touchscreen and offer an intuitive user interface backed by software wizards that simplify the production of custom test templates. Computer-controlled models are supplied with a PC-compatible software package that provides comparable functionality.

Full range of accessories

To complement its new TM1700 circuit breaker analysers, Megger offers a comprehensive range of accessories. As well as motion transducers , transducer mounting kits, and Static Dynamic Resistance Measurement (SDRM) kits, these include clamp-on CTs that allow the instruments to perform comprehensive first-trip testing, with full analysis of coil current signatures, whether the breaker has a single operating mechanism or separate operating mechanisms for each phase.

Widespread damage to roofs following winds often of gale force intensity provides a timely reminder of the value of protection against falling tiles, slates and other débris. The Klober Snowguard provides the twin benefits of preventing snow slippage and that of potentially lethal tile fragments. 3-metre, galvanised steel grids in powder-coated black, tile red or brown can be fitted over either profiled or flat interlocking tiles and slates. Klober MD David Arendell commented, “We have seen increasing interest being expressed in Snow Guard as a means of protection against falling tile, slate and mortar fragments. They are easy to fit either to homes or buildings with long roof spans as the grid sections are light and use support brackets which are positioned over the batten and tile”.

TROX UK has cemented its place in the air handling market with the launch of the X-CUBE Compact range of ready-to-use and pre-configured air handling units. The move means that TROX now has an air handling unit solution for almost every project from the very largest to the mid-range and the smallest application.

The arrival of the X-CUBE product range, during 2012, heralded TROX’s arrival as the only company in its sector capable of supplying, from a single source, virtually all components required for installing a complete air conditioning system. The new X-CUBE Compact, for volume flow rates up to 1.7 m3/sec extends the capabilities to encompass a wider range of applications. The high-efficiency unit has a heat recovery performance of over 80% and an even smaller physical footprint.

X-CUBE range

With the TROX X-CUBE range of freely configurable air handling units, TROX defines new standards in the air handling unit market and sets considerably higher standards for quality, flexibility, reliability, energy efficiency, and hygiene. The units in the standard X-CUBE range cover an air volume flow rate range up to 24 m3/sec with unlimited configuration options. They are designed for supply or extract ventilation of rooms and buildings, incorporating filtering, heating, cooling, humidification, dehumidification, and heat recovery. A special hygienic design is also available, ideally suited for hospitals and laboratories, and a weather-resistant version is included in the range for outdoor applications.

The outstanding performance of the range is underpinned by the very highest levels of independent assessment. Both the X-CUBE air handling unit and the X-CUBE Configurator design programme have been successful in achieving Eurovent certification providing independent assurance of the accuracy of the data and the stated performance criteria.

Energy efficiency is a vital feature of the range and the X-CUBE has been assessed by Eurovent as A class (the highest possible). This is due in part to the fine tolerances of manufacture. In contrast to other commercially-available air handling units, which have evolved incrementally over time, the X-CUBE has been created from a ‘clean sheet’ by a dedicated design team and with investment to create a new manufacturing facility purposed-designed for this product line. The X-CUBE’s enclosure incorporates a number of special construction and insulation features to ensure low leakage and optimised heat recovery. In addition, the TROX attenuators, with aerodynamically profiled frames achieve 30% less pressure drop than conventional silencers. Distance pieces in variable widths can be used to individually adjust the distance between the splitters. These also function as handles to enable the splitters to be removed when the casing requires cleaning. Intelligent control and highly-efficient IE2 (with options of permanent magnet IE4 compliant) motors also contribute to outstanding energy performance.

Hygiene of the unit is unparalleled as a result of the special design of the casing, its smooth surfaces and the way in which the components are installed. X-CUBE meets the VDI 6022 guidelines and the DIN 1946/4 requirements as standard, and an optional version of the unit, which meets AHU Guidelines 01, is available for even more demanding environments.

Highly flexible, the X-CUBE can be supplied with a choice of energy-efficient heat recovery systems, such as regenerative thermal wheel technology with hygroscopically coated thermal mass, plate heat exchangers or composite circulation systems to suit the application.

Installation and maintenance is simplified by the modular structure of the units. In addition the extended use of field BUS technology (communicating with virtually all building management systems) has simplified wiring. During commissioning and on-going operation, the intuitive design of the X-CUBE touch panel means that virtually all status information is available at a glance to assist safe, comfortable and error free operation.

The new X-CUBE Compact

The launch of the new X-CUBE Compact extends the range by bringing to the market a range of ready-to-operate and pre-configured air handling units that deliver the same excellent performance characteristics of the X-CUBE in the smallest of spaces.

Nine different units and a choice of two heat exchanger systems provide an extremely flexible range of solutions for volume flow rates of up to 1.7 m3/sec in small and mid-range applications. The units feature the same casing design and manufacture criteria as the X-CUBE for maximum energy efficiency, such as a seamless foam seal on each panel to ensure the low leakage class is maintained. High efficiency IE4 compliant EC motors and Eurovent-certified energy class A minipleat filters also contribute to energy savings. The X-CUBE Compact is pre-configured and ready to operate (plug and play), simplifying installation and maintenance, and the operating side of the unit can also be changed quickly and easily by simply exchanging the panels.

Dedicated Centre of Excellence for design and manufacture

Ahead of its move into the air handling unit market, the TROX Group built a new dedicated 15,000m2 production facility in Anholt, near the German-Dutch border, specifically for the X-CUBE. The new production facility is pupose designed and built for this purpose; it therefore offers the necessary flexibility for manufacturing air handling units in all common size ranges. The new advanced manufacturing technology with which the factory has been equipped has been selected with the high quality requirements of the air handling units in mind, and allows for a very efficient production process. For example, laser cutting of profiles, plastic profile machining, punching and sheet forming have been automated. New powder coating equipment and sealing foam application equipment have also been customised specifically for the requirements of AHU manufacturing.

TROX has defined a process which takes all factors into consideration: its new configurator software, the ERP system (Enterprise Resource Planning), the production equipment and also each individual worker. This process enables the company to provide customised, unique units of the quality and also at the price of a standardised production unit.
The total investment for the X-CUBE project amounted to € 20 million which, thanks to the excellent liquidity of the TROX GROUP, was completed without requiring credit lines.

“So often in our industry, new models are launched which are just an incremental improvement on a previous product, but with X-CUBE we have a completely different situation” explained Paul Wenden, Technical Director of TROX UK. “Here the designers have started with a completely clean sheet and created a product based on levels of performance, energy efficiency, flexibility and practicality that have not been available to customers in the past. The resulting product ranges re-write the rules and set new standards for air handling. This is an extremely exciting launch for TROX UK and will ultimately be an important stepping stone for our customers as they move forward with their energy efficiency and carbon reduction ambitions.”

‘One stop shop’

TROX is the only company in its sector capable of supplying, from a single source, virtually all components required for installing a complete air conditioning system. By providing a single point of accountability, TROX can bring additional peace of mind for customers, and remove risk from projects. During the design phase, the TROX sales and design engineers can advise on an integrated solution that captures the needs of their customers.

The Brick Development Association (BDA), the body that represents the clay brick and paver industries in the UK and Ireland, has strongly rejected claims by the Royal Institute of Surveyors (RICS) that a fall in UK Construction Output is due to shortage of bricks.

Simon Hay, Chief Executive Officer for the BDA, commented: “You only have to look at the statistics and forecasts from the Construction Products Association (CPA) to prove that these claims from the RICS are completely unfounded. Housing starts in Great Britain during 2013 are estimated to have increased by 24% and forecast to increase further in 2014 by 16% and 10% in 2015. Clearly house builders have been able to acquire sufficient brick supplies to significantly increase house building. Construction output is expected to rise by 3.4% in 2014 and by a further 5.2% in 2015, so there is no anticipation of supply problems causing problems in growth. If the brick industry was in ‘crisis’ as suggested by some areas of the media last year, this recovery would simply not have been possible.”

The CPA has also reported that the largest constraint to industry recovery continues to be public sector construction. Public non – housing output fell 27.2% between 2010 and 2012 with recovery not anticipated until 2015 when the impacts of capital investment growth begin to feed through.

“The lack of investment in public sector projects is what is really affecting the industry, not a shortage of bricks,” continues Simon. “The initial success of the government’s Help To Buy scheme and the growing pace of the economic recovery has meant that the construction industry has faced an upswing in demand. However, there is absolutely no suggestion that brick manufacturers will be unable to cope with the increased demand.”

The BDA reports that many manufacturers as well as stepping up production have continued production right through the winter to meet demand, but demand is being met. It urges builders to work closely with manufacturers and merchants to plan their deliveries and place orders in advance as was standard practise prior to 2008 and the credit crisis.

“The construction industry is in a phase of growth and optimism,” concludes Simon. “We are seeing a much needed lift in activity which is a really positive development and something our members are well placed to manage.”

As the demand for virtual reality in drawings increases, especially in the cruise ship sector, Chelsom continues to invest heavily in interactive 3D design technology, further strengthening its position as a market leader in the field of hospitality lighting design and bespoke manufacture.

To offer clients a fully integrated design service, a dedicated skilled technical project team has been created at the Chelsom head office. Through the use of e-drawings, sent electronically to clients worldwide, all parties working on a project have the chance to view designs on screen and make comments and amendments on the actual drawing which is automatically updated, revised and renumbered.

The visual language of the 3D drawings is understood worldwide, giving less chance for misinterpretation and error. Detailed views can be shown of any area of the fitting and the model can be rotated around 360 degrees in any direction. The use of 3D technology takes out all the guesswork out of viewing complicated design proposals, as the client can see the proposed product in much finer detail. Errors and design modification requirements are caught early rather than after samples have been made.

The benefits of 3D modelling are vast; the images are more realistic, with the addition of colour, texture and lighting effects; the virtual product can be displayed against a specific background, an in-situ backdrop, or dropped into a 3D model of a building; manufacturing timescales can be drastically reduced as conventional sampling is no longer required.

Said Bob Neville, Operations Director, “Chelsom is a major supplier to the worldwide cruise industry. Some of the feature luminaires we are quoting for are spectacular in terms of design and enormous in scale, so this technology really puts us ahead of the game.”

The immediate visual aesthetic of the new £27m, 1515m2 Stonehenge visitor centre stems from its combination of glass and timber facades. At closer quarters, however, the 36 x 78.4 metres canopy and its 211 canted steel supports undoubtedly take the eye. 3600m2 of VMZINC Composite panels in QUARTZ-ZINC® have been used for the underside soffit area, the edge of which has an elaborate pattern of perforations. The multi-layered panels are made up of two 0.5 mm thick zinc sheets bonded either side of a mineral-rich polyethylene core. Though only 4mm thick overall, they offer exceptional smoothness, rigidity and dimensional stability and as a result can be used in lengths of up to 6 metres.

Australia’s Denton Corker Marshall won the competition to build the centre twice. Their first scheme was dropped when government budget cuts forced abandonment of a plan to build a tunnel to hide the A303. They responded to the World Heritage Site requirements by designing another building of contemporary style at ‘Airman’s Corner’.

A natural palette suited to the rural landscape was a key element of the brief and zinc was chosen for its sustainability, colour retention and self-protecting patina. The building has been designed to sit lightly in the landscape and to be demonstrably reversible. Its position in one of the lowest lying areas and remote location, distant from residential development, minimises any visual intrusion in the landscape. The contemporary steel structure and lightweight framed walls require minimal substructure so that, if removed, residual environmental impact will be minimal.

Attention of up to 1,000,000 visitors each year will undoubtedly be drawn to the zinc by the height of the building which, at up to 8 metres is comparable to the tallest trilithon stones. In addition to being visually distinctive, the canopy is considered to be one of the most notable architectural elements of the design.

The building has been designed to achieve high sustainability targets so local, recyclable and renewable materials were used wherever possible. A sustainable, fuel-efficient approach to heating and cooling greatly reduces energy use and carbon emissions while VMZINC was able to demonstrate that over 90% of material used in construction projects is already being recycled. Energy consumption in zinc manufacturing is also by far the lowest of any metal faÇade or roofing system. Not only can it be rolled at a lower temperature, less than half the energy is used in the manufacturing process compared with copper, stainless steel or aluminium. Air emissions are as little as 0.05mg/m3 while analysis of zinc concentrations in the Rhine, which passes through one of Europe’s areas of greatest industrial intensity, confirms that the balance is well within accepted environmental limits.

Such was the interest in zinc that the pod beneath the roof which provides ticketing and guide facilities is also clad in it. It provides a notable contrast to the timber and glass without suggesting that the divergent materials clash. With its range of colours now extending to blue, green, red and brown the scope it provides has never been greater.

TROX chilled beams and flow rate controllers are ensuring that an impressive new sixth form college in the north east of England achieves the ideal indoor environment for learning without costing the earth.

The £22 million project to create the Newcastle Sixth Form College has provided a state-of-the-art world-class learning environment. The 11,000 square metre building is the only dedicated sixth form college in the city of Newcastle. Designed specifically to meet the needs of 16 – 18 year old students, it incorporates specialist facilities including dance and drama studios, science laboratories and art/design workshops in addition to large social spaces such as a bistro and internet café.

Achieving the optimum indoor environment for learning was a key requirement for the new college. Equally important was the energy efficiency of the building, which has been designed with a number of sustainability features, including a ‘green roof’. A key challenge was how best to cater for widely differing occupancy levels in zones across the site throughout the day. Optimum comfort conditions for students and staff needed to be maintained whilst ensuring that the HVAC system could adjust to match demand to prevent wasted energy.

The HVAC products supplied to meet the demanding requirements included TROX Multi Service Chilled Beams (MSCBs) and variable volume flow rate controllers. The MSCB’s are based on the energy-efficient air-water technology of the popular TROX model DID632 active chilled beam. These units are ideally suited to areas with high cooling loads, combining the aerodynamic properties of ceiling diffusers with the energy benefits of load dissipation using water. They are suitable for both recessed and exposed installations in new buildings and for the refurbishment of existing buildings with clear room heights between 2.6m and 4m.

The chilled beams installed at Newcastle Sixth Form College supply heating, cooling and ventilation throughout the building as well as incorporating lighting. As the units are extremely easy to maintain and do not require cleaning they offer significant benefits for the demands of a busy academic site such as this.

In addition, TROX variable air volume flow rate controllers have been installed to ensure that energy usage can ramp up and reduce down in line with changing occupancy levels in each zone. The products supplied are TROX TVR and RN Models. The TROX type TVR is a circular flow rate controller for variable supply or extract air, suitable for almost all control, regulation and shut-off tasks in room air conditioning systems. The unit incorporates factory-fitted and tested mechanical and electronic components, and contains an averaging differential pressure sensor for air flow measurement, and a control damper. The control damper, with plastic seal, complies (when closed) with the air tightness requirements of EN 1751. The flow rate control is a closed circuit system with external power supply.

The TROX type RN is a mechanical automatic controller for constant volume flow systems which operates without external energy. Volume flows are set with an external pointer.
