JS Humidifiers has supplied and installed two Neptronic SKE resistive steam humidifiers and reverse osmosis water treatment systems to leading data centre, Citadel 100, in Dublin.

The steam humidifiers can supply up to 140 litres of moisture every hour to help control the humidity around the 7,500m2 data halls and the water treatment systems remove most of the minerals from the supply water prior to boiling.

George McDonald, technical manager at Citadel 100, comments, “We need to maintain 50% relative humidity in the data halls to prevent static build-up and maintain a healthy environment. Without the humidifiers the atmosphere can drop to 25%rH which is a risk to both people working in the area and the equipment.

“The humidifiers operate 24 hours a day, seven days a week at 80% capacity. The Neptronic SKE humidifiers have performed well since they’ve been installed and we’ve been able to fit and forget them with absolutely no issues.

George continues, “The reverse osmosis water filters have also been very effective. Previously we had to service the humidification system every one and a half months to empty to the limescale from the boiling chambers. This took about a day to do. However, with the reverse osmosis filters in place we only have to service the units once every six months.”

The Neptronic SKE has 98% metal construction and has been designed to keep consumable components to an absolute minimum. The heating elements are made from scale-resistive Incoloy 825 super alloy, which when heated causes any limescale that does build up to crack from the surface in small manageable pieces. These are then mostly washed to drain during normal operation.

When combined with a PureFlo 100 reverse osmosis water treatment system, which removes 90% of the minerals from the supply water, the maintenance requirements of a Neptronic SKE are dramatically reduced as very little limescale builds up in the boiling chamber. This is in stark contrast to electrode boiler type steam humidifiers, which regularly require expensive replacement boiling chambers to combat limescale build-up.

JS Humidifiers is the UK’s largest humidification company with the widest range of products and offers a service of advice, design, supply, installation and maintenance. It also offers a comprehensive range of humidifier spares, not only for JS equipment but also for a large range of different manufacturers’ humidifiers, mostly available ex-stock.

Polypipe adds elegance rainwater system to its portfolio of above and below ground waste and drainage products

Leading rainwater system manufacturer Polypipe has added a new, stylish range of guttering and downpipe products to its extensive range of above and below ground waste and drainage products.

‘Elegance’ offers a decorative effect that combines the look of a traditional cast-iron system with all of the product and installation benefits of using PVC-U as the manufacturing material.

‘Elegance’ is a lightweight, low maintenance product suitable for new build and renovation projects – in particular in conservation areas or in areas where older style homes predominate. And whilst it looks great, for installers, the benefits of ‘Elegance’ are many.

It’s easy to store and handle and quick to assemble and install – reducing installation costs and making it an attractive option for the end customer. It’s supplied ready to fit without the need for painting or protective coatings and Polypipe’s unique lugged brackets ensure a secure fit whilst remaining compact and unobtrusive in design and their decorative hopper has been designed to replicate the look of heritage cast iron systems.

The new Polypipe ‘Elegance’ range is available from a wide ranging network of plumbing and builders merchants across the UK.

Elegance is the latest addition to a wide range of traditional PVCu rainwater systems available from Polypipe Building products that currently include half round, square section, Polyflow Deep Capacity gutter and Ogee Extra and Sovereign High Capacity gutter systems options – most available in grey, black, brown or white.

In addition Polypipe has just launched a new barrier pipe solution designed to ensure the safe delivery of drinking water through redeveloped sites that may have been contaminated by previous industrial and commercial use. It’s available now from merchants across the UK.

Polyguard protects drinking water against a wide range of potential contaminants including organic, inorganic, corrosive and toxic elements offering all the benefits that come with a plastic pipe system – in particular its light weight and flexibility –in this case coupled with the protective, impenetrable aluminium barrier that runs the fill length of the pipe. It offers a cost effective, time saving alternative to traditional materials – copper in the main – which is prone to damage on site along with the increasingly valuable benefit that it offers increased on site resistance to damage and theft, from a robust product with no scrap value. It‘s the ideal response for private and social housing developers, building new homes on brownfield sites across the UK.

Manufactured by Polypipe, the UK market leader for above and below ground drainage, plumbing and water management systems, the Polyguard system offers a comprehensive range of both pipe and brassware fittings providing a complete potable water supply solution. The fittings that are available as part of the system are made from DZR brass which are impenetrable to contamination –there is no need to cover the fittings or wrap joints.

Polyguard pipe is constructed from two layers of Polypipe’s proven polyethylene, adhered to a layer of aluminium. The inner layer of polyethylene carries the water whilst the outer layer provides protection for the aluminium layer form damage. Brown stripes on the outer layer ensure the pipework is easily identified on site.

“Polyguard is available in three pipe sizes – 25, 32 and 63mm,” says Product Manager Simon Green. “It offers the best potable water supply protection option available and can be ordered through merchants with other Polypipe purchases. It’s approved under regulation 31 of the Water Supply (Water Quality) Regulations 2000 and conforms to necessary standards.”

Dock bumpers may be one of the smallest – and seemingly most insignificant – pieces of equipment in the loading bay, but they can increase safety and prevent considerable damage to both the vehicle and the infrastructure of the building.

Leading high quality loading and unloading equipment supplier Thorworld Industries Ltd has introduced its new sliding nylon dock bumper – not only does it last approximately four-times longer than standard nylon dock bumpers, but it also ensures that customers can enjoy years of cost-effective, shock-absorbing protection, with reduced vehicle repair and building maintenance costs.

So why are dock bumpers needed at all? Reversing a large vehicle up to a loading dock can be a difficult task, especially if the driver is unfamiliar with the particular premises and loading bay area. Misjudging the stopping distance is therefore an all too common occurrence, which causes the vehicle to ram into the dock and jolt the structure. And with a 30 tonne vehicle travelling at just 4mph, even reinforced docks can be damaged quickly, resulting in costly repairs – and that’s where Thorworld’s new sliding nylon dock bumpers come in.

The Thorworld sliding nylon dock bumper features a heavy-duty black powder-coated steel frame which is fixed to sound concrete or steelwork on the loading dock. The frame houses a solid block of nylon, and a unique fixing method (patent pending) enables the incorporation of a thick, heavy duty rubber packer at the rear to ensure maximum shock absorption. As a result the Thorworld sliding nylon dock bumper helps to reduce damage to both the building and the vehicle, as well as helping to protect any goods being carried.

What’s more, the innovative sliding design means that each bumper can be turned upside-down and back-to-front to ensure even wear, thus extending its lifespan by as much as four times that of a traditional nylon dock bumper and significantly more than that for conventional rubber dock bumpers.

Added to this, the sliding action helps to extend the bumper’s lifespan still further because the nylon can move with the vehicle thus minimising abrasion damage – making them ideal for use with air suspension trailers

The smooth front surface of the nylon, without any holes, also helps to protect both the vehicle and the bumpers themselves from potential damage that can occur when protruding objects on a vehicle get caught in the fixing holes on standard dock bumpers.

The standard 760mm (30″) long version is suitable to cover a wide range of vehicle heights for most standard applications, however they can be fitted above the loading dock with appropriate support and can also have corner cut-outs to allow unrestricted access to the vehicle in above dock applications.

Speaking about its new sliding nylon dock bumpers, John Meale, managing director of Thorworld Industries, said: “Without installing dock bumpers, an organisation with multiple loading bays could incur literally tens of thousands of pounds in repair bills every year and yet this damage is entirely preventable, simply by investing in a low cost piece of safety equipment.

“Our new sliding nylon dock bumper offers exceptional value-for-money and whilst the initial purchase cost might be slightly higher than for standard non-sliding versions, when the nylon wears in one area, you can simply rotate and reverse them, extending each bumper’s effective working life by up to four times. What’s more, once the steel framework is fixed in position, the nylon insert can then be easily changed or rotated in seconds – without the need for any special tools.”

Thorworld is firmly established as one of the foremost designers, manufacturers and suppliers to the loading bay and materials handling sectors and is recognised as both a market leader and innovator in the supply of quality engineered equipment.

The company provides a one-stop, single source for an extensive range of high quality loading bay and materials handling products, safety aids and accessories, including dock shelters and seals, dock levellers, modular loading docks, dock plates and boards, dock and vehicle bumpers, wheel chocks, vehicle restraints, traffic lights, wheel guides, alignment curbs and mobile yardramps (available for purchase or rental on a sale or return basis through the company’s RentARamp operation), together with the Truckloada mobile yardlift and the Dockloada scissor lift platform.

aM&T (automatic Monitoring & Targeting), the correct selection and application of meters combined with AMR (Automatic Meter Reading) and M&T (Monitoring and Targeting) is a key element in Best Practice Energy Management.

Micronics has combined its considerable experience in the Clamp-On – Ultrasonic metering field with its Reseller Partners expertise in AMR & aM&T to prepare this introduction or refresher paper for Energy Managers, which covers the fundamentals of developing an effective energy and water metering strategy, AMR communication options and an overview of the functionality and associated benefits of an effective aM&T system.

An aM&T system can be considered in three logical parts, which are

• Meters
• AMR (Automatic Meter Reading)
• M & T (Monitoring and Targeting)

Meters

Meters are the foundation blocks of an effective aM&T system, they are the primary measuring element and as such are fundamental to the accuracy of the overall system. They provide the basic data, which needs to be accurate and reliable. So the starting point when considering an aM&T system for an existing site or building is a Metering Audit to establish the extent and quality of the current meter installation. The Audit can be a daunting task but it is an essential first stage and may require the installation of temporary non-invasive, portable measurement devices to establish the quality of the existing meters. Temporary measurement instruments include Clamp-On Ultrasonic flow meters for liquid flow or heat/cooling energy measurements or Clamp-On CT’s for electricity measurements.

Having established the scope and suitability of the current meter installation both Primary and Secondary the next step is to develop an aM&T plan which supports the management objectives and operational needs of the organisation. This will identify Energy Accounting Centres (EAC’s) and the key water and process measurements required to manage the Energy and Water consumption for the building or site, which in turn will highlight the meter shortfall and new meters required.

The Audit has profiled the current meter installation and the aM&T plan has identified the additional metering requirements. Selecting the new meters is the next step and the first stage is to establish a specification for each metering point including the accuracy, range, repeatability, reliability and connectivity options required. There is a wide range of options available for measuring energy and water utilising different technologies. Selecting the correct meter for each measurement point will require professional guidance from a consultant and or advice from a range of suppliers or suppliers who offer a wide range of metering alternatives. There will be price/performance tradeoffs for different options and it will also be important to consider the installed price for a particular option, installation disruption and lifetime maintenance and service issues costs. For example in some applications the supply price of a Fixed Ultrasonic Clamp-On meter may be more expensive than a more traditional in-line mechanical meter, but the installation cost, installation disruption, life time maintenance and in-line energy cost will be considerably less with substantial savings!

AMR (Automatic Meter Reading)

A meter that cannot be automatically read and recorded is not worth having because experience shows that it’s very unlikely that it will be read and if it is manual reading and logging of meter readings is open to error! All modern meters have some form of connectivity or means to connect them to some form of AMR (Automatic Meter Reading) system or data logging device. However, whilst most existing meters will have or can be adapted for remote reading for some it will not be possible or cost viable and this should be identified in the Audit.

Having established that all meters should have the facility for connectivity to an AMR system or have on-board data logging the connectivity can take many forms. These range from a basic 1/2-hour pulse or analogue typical 4 to 20mA signal for continuous recording of actual flow or consumption to smart meters where all the meter information is available in a digitally encoded form for AMR by various means. The latter is preferable as it reduces the possibility of an error between the actual meter reading and the AMR signal; however, it is more expensive and not available on all meter types.

Given suitable connectivity there are AMR systems with a wide range of communication options including

1. A Twisted Pair of wires connecting all the meters together often termed a Daisy Chain. Each meter will have an integral communication ability e.g. smart or add-on interface unit, which will be linked via the Daisy Chain back to a master data-collector/logger. There are many variants with M-Bus a European AMR standard being the most sophisticated.

2. Internal and external PSTN networks where the telephone system provides the communication link.

3. Ethernet based systems where each meter is a LAN node on the network

4. Low power – licence exempt radio communications where each meter or small group of meters via a local data collector has a radio transceiver on a local network.

5. GSM – mobile radio communications where each meter or small group of meters via a local data collector has a GSM link to a master data-collector/logger.

6. Web enabled systems where a cluster or group of meters is read and the data is automatically transferred to an Internet service provider for remote access.

The above is not an exhaustive list and the actual AMR system for an individual Building, Campus (multiple buildings on a site) or organisation estate will depend on many factors and in most cases the best solution will be a combination of the above.

For some smaller site applications a Portable Clamp-On metering device such as the Micronics Portaflow 300 or similar may be sufficient to establish consumption trends and profiles of water and water based heating systems when combined with appropriate Clamp-On temperature sensors.

M & T (Monitoring and Targeting)

Having gathered the meter reading data e.g. 1/2-hour through whichever form of AMR system the next step or task is to automatically convert the data and that’s all it is at this point into useful information and exception reporting!

Current aM&T systems encompass a vast range of application programs including Monitoring and Targeting, which manipulate, analyse and convert the vast amount of metering data gathered by the AMR system into useful information.

These systems will be multitasking, multi-user utilising standard operating systems. The databases employed may also be standard or in some cases proprietary and the systems are often scalable from a desktop PC to an Internet server. Your aM&T plan will have clearly defined your requirements in this respect.

Generally provided programs will include

• Meter Profiles or Reports
• Virtual Meters or Group Profiles or Reports
• Utility Shadow Billing & Automatic Billing
• Benchmarking
• Budget Reports
• Bar Charts
• Cusum
• Pie Charts & Tables
• Period on Period Comparisons
• Degree Day Monitoring
• Environmental Report
• Climate Change Levy Reports
• M & T – Weather, Occupancy, Production variables, Signature, Theoretical
• Custom Management Reports
• Exception Reporting

At first site the above can appear rather daunting and it would be fair to say that the top end M & T software associated with some aM&T systems is over flexible and consequently over complex in the set-up and configuration. It’s important to strike the correct balance between flexibility or individual customisation and ease of use. And of course the IT skills or level of Energy Managers varies so the ideal solution is a system that offers a wide range of ready made templates or pre-configured reports but with the option for customisation of reports etc by the individual as and when required.

To conclude this brief introduction, aM&T systems are a valuable tool, which when designed and applied correctly will deliver the essential visibility and measurement information required for effective Energy, Water and Cost management!

Swish Building Products has launched a new low carbon rainwater system made from 84% recycled material, that brings tons of post consumer PVC back into use.

These rainwater profiles are unique in the UK because the recycled material contains post consumer waste from old PVC window and gutter systems that have been removed from buildings when refurbished or demolished.

Greg Wilde, of Swish Building Products said: “Swish rainwater systems are ideal for designers who want to specify quality products that have a significantly reduced carbon footprint. Manufacturing a product that effectively marries a recycled core with a virgin skin saves 70% of the CO2 that would be produced by manufacturing with virgin material.”

These gutters and pipes have a two-tone appearance featuring a grey core and coextruded outer skin of virgin material to enhance the external appearance and aid colour matching. This technology gives it exactly the same weather resistance and longevity as products manufactured from virgin material.

The new gutter range comes in Round, Square and Ogee designs and each style is available in White, Black and Brown.
