Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT330 has been upgraded with LAN and WLAN communication options and a display alarm.

With the new Ethernet communication options you can connect the transmitter into a computer network providing a virtual terminal connection between the transmitter and a PC. Communication is then possible using for example Telnet software. Each transmitter is given an IP address, making it a uniquely addressed device in the network.

The LAN and WLAN options make it easy to add a new humidity transmitter to an existing Ethernet network. Also, applications that do not allow holes through walls and ceilings, or the installation of new cables, benefit from this solution.

Display Alarm

A new display alarm function is now a standard feature in Vaisala humidity transmitters equipped with a built-in display. With this function the user can set alarm trigger limits for two distinct measured quantities. When the trigger limits are exceeded, a real-time alarm appears on the display.

With greater use of roof windows for their contribution to interior design, there has been a marked trend towards use of windows used in combinations and L-shaped windows in particular. Such windows are equipped with a locking mechanism to prevent accidental opening by children. The vertical element is typically installed beneath a standard roof window and linked together using a vertical jointing module. This significantly increases the amount of light entering a room and increases the field of view. The roof window handle is positioned at the lower part of the sash enabling easy operation.

Fakro Managing Director Noel Shanahan commented “L-shaped roof windows are the ideal alternative to dormers as they are quicker to fit and avoid detailing problems. By extending the window line into the wall, they give greater scope to the designer and householder, while providing a stylish appearance at lower cost”. Products are even available in conservation style, with the traditional sash bar down the middle of the window, and black metal cladding and flashing.

JS Air Curtains is launching the new Intensse air curtain with a built-in air freshener, UV air purification, strip light and energy saving technology. The Intensse’s many features and very attractive design make it ideal for use in modern commercial premises like banks, hotels and offices.

As well as maintaining pleasant internal temperatures the unit further helps improve the indoor environment by incorporating a noise reduction system that keeps operating noise to less than 46dB(A).

The Intensse’s air freshener has six different scent options in cassette form. They are inserted into the top of the air curtain near to the air inlet and will gently release an aroma for up to 12 months, after which they can be easily changed.

To improve the quality of air flowing through the system a hidden UV lamp kills airborne pollutants such as fungi, bacteria and viruses. An additional strip light on the air inlet helps add to the attractive appearance of the air curtain. Green, red and blue bulbs are supplied as standard with the air curtain along with matching colour trims for the side panels so the user can select their chosen colour if desired.

Fast heat wire elements and an energy saving power regulation system reduce energy consumption by up to 20% compared to standard electrically heated air curtains. The wire elements within the unit heat up to temperature in just 5-10 seconds rather than the 120 seconds it takes a stainless steel heating rod to reach temperature. Once the internal temperature nears its set point the air curtain will pulse the power to the elements, reducing the overall energy consumption and maintaining a more consistent internal temperature.

The Intensse is available in 1m, 1.5m and 2m lengths and with electric or low pressure hot water (LPHW) heating. Outputs range from 9.5kW to 19kW for electric heating and 17.5kW to 36.5kW for LPHW. A digital wall mounted control panel allows full control over all functions and can be used with internal and external temperature sensors for intuitive comfort control.

JS Air Curtains supplies an extensive range of air curtains, as well as bespoke solutions, for all commercial and industrial applications. JS’ in-house project management division also provides a smooth, hassle-free installation service that walks the customer through from design specification to post-installed product training.

As endorsements go, they don’t get much bigger than Marks & Spencer, but that’s exactly what Dulux Trade, the industry leading manufacturer of quality paint systems, received at EcoBuild for their latest innovation, Ecosure.

Dulux Trade is the first major paint manufacturer to have taken significant steps towards creating a credible environmentally sustainable paint product for the professional market. Ecosure has been specifically formulated to have demonstrable reductions in embodied carbon and Volatile Organic Compounds (VOC), two key sustainability criteria.

Developed using an approach based on scientific rigour, these reductions have been achieved without compromising on performance. Additionally, accurate measurement of these reductions has been made possible by the use of an ‘Environmental Impact Analyser’, developed in conjunction with Forum for the Future – the leading independent sustainability experts.

Speaking at EcoBuild 2008, Crispin Burridge, Sustainability Manager for Marks & Spencer, said: “The idea of an environmentally sustainable paint has been around for some time, but has been difficult to use on larger scale projects. I'm delighted to see Dulux Trade has risen to the challenge by investing time and money into producing such a paint product. We particularly welcome the opportunity to specify paints for our stores with lower VOCs and a reduced carbon footprint that support a number of our Plan A commitments.”

David Shepherd, Brand Manager for Dulux Trade, commented: “Ecosure signifies a real milestone for us. It is a ‘step towards greener’ and our acknowledgement that we are embarking on a journey toward a more sustainable future. We need, and fully intend, to move toward more environmentally sustainable products and ways of working.

“It is fantastic that Ecosure is already getting such a positive reception from existing customers and key UK firms such as Marks & Spencer. Within the retail arena, Marks & Spencer is driving the environmental sustainability agenda. Their commitment to this issue, highlighted by their bold ‘Plan A – because there is no Plan B’ 5 year strategy to tackle the biggest issues facing their business and the globe, is unquestionable. It is great that we can help them achieve this goal.

“Being green is no longer an option and the emphasis placed on companies to become environmentally friendly can only intensify. UK businesses need to make the investment now to ensure they are meeting sustainability targets and working within increasingly green environments.”

Ecosure is available in Pure Brilliant White and an extensive colour range from the Dulux Trade colour offer, ensuring that you don’t even need to compromise on design.

Crispin concluded: “We hope that Ecosure will help achieve a more sustainable specification for M&S stores, which is why we are trialing it at our new White City store, which is due to open at the end of the year. On successful completion there, we intend to have it included as part of our paint specifications.”

Ecosure will be available from selected Dulux stockists at the beginning of May. For more information visit www.duluxtrade.co.uk/ecosure

With more than a third of house buyers adding underfloor heating to their top five wish list, the new OSMA Underfloor Heating (UFH) Electric Mat system from Wavin will come as a welcome addition to its already extensive range of ‘Genius’ UFH options.

The new UFH Electric Mat systems are available in 100W/m² and 150W/m² to accommodate different floor structures and are the perfect option for the renovation and refurbishment market.

The Electric Mat system complements the existing OSMA UFH range giving home owners complete flexibility when it comes to choosing the right UFH option for their individual needs.

The Electric Mat 100 is suitable for all types of subfloor including timber and can be used under almost all floor finishes including tiles, stone, vinyl, wood, laminate or carpet. The Electric Mat 150 is the perfect choice where a higher output is required and must be installed on a solid subfloor using a ceramic floor finish.

The benefits of the UFH Electric Mat are clear. Its thin construction, measuring just 5mm, makes it a truly versatile option for projects that don’t have the depth of space for traditional screeded UFH options – usually requiring 122mm build up from the subfloor. The total overall floor build up thickness using the Electric Mat could be as little as 6mm. Not only that, it’s fast and easy to install and requires no special skills to complete the mat installation.

Awkward shaped rooms or small areas such as bathrooms are ideal room scenarios for the Electric Mat. The self adhesive glass fibre mesh can be easily cut to accommodate curves and corners in the room. The Electric Mat 100 is available in two metre and four metre lengths and the Electric Mat 150 is available in six metre and ten metre lengths – providing complete flexibility for every room type.

The new Electric Mat is recommended for use with the OSMA UFH PRT-E dual sensor thermostat to give the home owner complete control over its use.

The Electric Mat system forms part of the six OSMA UFH options available from Wavin, along with Staples, System plates, Pocketed polystyrene, Foiled polystyrene and Modular chipboard, providing an option to suit all buildings and floor constructions. The ‘Genius’ OSMA systems have been developed using the cleverest technology but are still simple to understand and easy to install. Even the most basic OSMA UFH system, staples, works on the genius principle and has been designed to give full flexibility for screed floors even if small or irregularly shaped.

Marflow Hydronics has launched the Remote Commissioning concept, an innovative approach designed to simplify the installation and commissioning of fan coil and chilled beam systems. It is able to significantly reduce the cost of installing such systems, while also ensuring they operate at optimum efficiency.

One element of the concept is the use of addressable pressure independent 2-port valves from Belimo, linked to a BMS or local controller. This enables valves to be adjusted remotely from a central PC or other control device without the need for an engineer to enter the ceiling void. Consequently, as well as speeding up commissioning, it also enables quick and easy re-configuration of systems – to accommodate layout changes within the space, for example.

“Most people don’t realise that centralised, remote control, which is widely used in other building services systems, can be applied to chilled and hot water systems,” explained Marflow’s Martin Lowe. “However, the Remote Commissioning approach is about more than new valve technologies. It is designed to give the specifier and installer complete control of the project from start to finish. As such it also incorporates centralised management of valve information and hydronic performance data, advanced pre-fabrication techniques and innovative commissioning processes using Marflow’s single station balancing method.

“At its heart is a recognition that design, installation and commissioning practices in many projects have failed to keep pace with key developments in the industry. These developments include the growth of design and build, skills shortages and the increased use of multi-national labour forces, and the opportunities provided by modern valve technologies.

“As a result, this outdated approach is failing to deliver the best result for the contractor and the end client in many projects,” he continued. “Our approach seeks to rectify the current fragmented approach to system design by creating a single system from one source; a complete process that equals a complete solution,” he added.

The system can be divided into several stages:

Smarter design

Attention to detail from the start of the project and anticipating problems before they occur can optimise the use of site labour, compensate for inherent skills shortages or inexperienced operatives and minimise the risk of installation errors.

Management of information

Many problems arise from poor communications between members of the project team The Marflow system brings all valve information and hydronic performance data into a single, purpose-designed spreadsheet package that is continually updated, with any changes being distributed to all relevant parties.

Innovative installation

Rather than seeing pre-fabrication as simply a way of transferring site work to another location, the Marflow approach takes full advantage of the benefits of pre-fabrication. These include use of innovative valve assemblies, location of all valves for each zone in a single location that also contains information about the system, facilitation of single station balancing (see below), pre-insulation of the manifold box and use of pre-insulated, flexible pipe.

Reducing installation errors

Pre-fabricated assemblies are supplied complete with all components, using labelling and colour coding of connections to ensure correct installation. Full instructions are provided, using diagrams so that language is not an issue.

Single Station Balancing (SSB)

Unlike proportional balancing, which is laborious and time consuming, the SSB method uses a subtraction technique to identify problem valves. This is based on knowing the design flow rates for each individual valve and, therefore, the total flow rate for that fan coil group.

Assuming all the valves are functioning correctly, isolating each valve will have a predictable effect on the total flow rate for the remaining valves. Where an unexpected result is observed it is a simple matter of elimination to quickly identify the valve that causes this, enabling the commissioning engineer to home in on the problem area.

SSB is discussed in more detail in the background notes

Innovative valves and controls

The Remote Commissioning concept takes full advantage of the functionality of Belimo’s pressure independent two port control valve, linked to a BMS fan coil or chilled beam controller, and an actuator that can be set from a remote location to the required position to give design flow rates. This allows only two valve sizes and four valve configurations of flow and return to be used in achieving the design performance.

The BMS controller, housed in its own case, can be wired to the actuator via pluggable leads and sockets within the assembly. A power plug socket is provided for mains power to the controller and to allow switched power to the fan on the fan coil unit. A plugged cable is also provided from the controller to the fan coil unit supplying power and the temperature sensor. The communication cable to the BMS is also a pluggable connection.

In summary, the Marflow system is designed to achieve the following:

• Simplified installation and commissioning by design
• Full exploitation of the benefits offered by the latest valve technologies
• Efficient management and sharing of critical system information
• Regular updating of information to all parties to reflect design changes as the project proceeds
• To enable smaller contractors to realise all of the benefits that are often confined to larger, better-resourced companies through the innovative use of information technology
• Quicker installation with less site-work through advanced pre-fabrication techniques
• Reduced risk of installation errors through innovative colour coding and labelling techniques
• Faster, more accurate commissioning using innovative ‘single station balancing’ methodology
• Use of the latest addressable valve technologies to allow valves to be adjusted from a remote location, without needing to enter the ceiling void.
