PRODUCT FINDER Airflow promotes efficient


design Airflow now offers a full complement of Passiv Haus approved MVHR units, ranging from smaller domestic units through to larger commercial applications.


The DV150, Duplexvent Multi 50 and 80 and Duplexvent Flexi 1600 and 2600 have all been given the stamp of approval by the Passive Haus institute. Complying with the stringent test requirements means the unit is perfect for incorporating into Passiv Haus schemes as part of the energy efficient design and construction process. Available in three sizes up to 3600 m³/h, the Duplexvent Flexi units have the highest thermal efficiency (over 90%) and are the only Passiv Haus Institute certified Commercial MVHR units in the UK. The units, which are also SAP Appendix Q Eligible, use high efficiency heat exchangers to recover up to 90% heat from the expelled air.


The DV150 features a twin skinned casing which retains all recovered heat, and the unit is designed with a Triple Filter system for top class hygiene performance, whilst the DV1600 for commercial applications offers the ability to position the unit on the floor or on the ceiling in a suspended configuration.

Dimplex maximises system


savings Dimplexʼs new EC-Eau range of heat pump hot water cylinders offers mains pressure hot water with eco-credentials, with low running costs, reliable hot water and fantastic flow rates, for a wide range of domestic and light commercial installations. Manufactured from a high proportion by volume of recycled materials, the heat pump cylinders offer the same efficiencies as the rest of the EC-Eau range, with every aspect of manufacture and performance designed to minimise environmental impact. Available in capacities from 125 to 300 litres, the range has been specifically sized to match the requirements of Dimplex heat pumps for optimal performance, although the cylinders are suitable for use with a wide range of heat pumps.


For heat pump systems where space is limited, the range includes heat pump cylinders with integrated buffer tanks; these are available in capacities from 125 to 210 litres, all with a buffer capacity of 75 litres.


The design features a corrugated heat exchanger to give a large surface area, maximising the transfer of heat generated from renewable energy to the stored water for optimised heat pump efficiency and reduced running costs.

New PV cable from


Amphenol


Amphenol Industrial Global Operations, a


global leader in interconnect systems, now offers a single jacket photovoltaic (PV) cable used for interconnection wiring in grounded and ungrounded PV systems. Amphenolʼs PowerLink solar cable is ideal for use on utility solar farms and in commercial and residential solar projects.


Designed with a smaller outer diameter than a standard dual jacket, the single jacket PV cable is more malleable and makes crimping connectors easier.


The new cable, which is available from 6 AWG to 18 AWG, is sunlight resistant and suitable for direct burial. It has a temperature rating of 90°C wet or dry and a cold bend of -40°C. Its voltage ratings range from 600V to 2000V and this new RoHS compliant, UL4703-rated cable has a flammability rating of VW-1. Unlike a dual jacket cable that is only available in black to meet 720UV requirements, the PowerLink solar cable is manufactured in a variety of colours including black, white, red, blue, green, yellow and orange.

Staff, swimmers and fitness fanatics at Newton Abbot Leisure Centre, Devon, are benefitting from highly efficient heating and hot water thanks to three 200kW ADI-NOx CD boilers, two 300-litre Gemini calorifiers and a


Minifill Pressurisation Manager – all supplied by MHS Boilers. The upgrade of the buildingʼs boiler plant will reduce carbon emissions by 102.3 tonnes per annum and provide significant energy savings, ensuring a payback within seven years. The new boilers have replaced 12 ageing units as part of the


Councilʼs commitment to reducing energy costs and tackling climate change. This has been laid out in its recently approved Energy and Carbon Reduction Plan 2012 – 2017, which was created in partnership with The Carbon Trust. The plan contains 34 individual projects aimed at cutting the Councilʼs carbon dioxide emissions by 20% by 2017 and saving up to £881,000. The ADI-NOx CD range of high efficiency boilers solve the problems caused by replacing old atmospheric boilers in compact plant rooms. With outputs from 68 to 905kW, it is designed to resolve difficulties with limited installation space, with incredibly compact dimensions that belie their powerful outputs.

Havells launches


energy meters


Havells has launched QuikWire - a new range of energy meters that incorporate plug and play


technology to eliminate wiring errors and reduce installation time. Part L2 Building Regulations has had a significant impact on how electrical distribution is designed for commercial buildings. The requirement to provide energy monitoring at sub distribution level has created many challenges for the installer. A common problem is the incorrect installation of an energy meter through complicated wiring and confusing programming settings. This can directly impact on the overall final cost of a project with site revisits required to re-validate the installation and operation of energy meters. All this can be avoided by using the Havells QuikWire solution. Using a simple plug-in design ensures meter installation is quick and right first time.


The new QuikWire plug-in metering solution for Havells PowerSafe MCCB panelboards is designed to utilise side extension boxes to facilitate mounting of meters for both outgoing and incoming circuits.


The new plug-in meters, current


transformers and harnesses have been specifically engineered to complement the panelboard to ensure the meter installation is quick and easy.

Powrmatic enhances air


distribution Powrmatic has introduced the Midea Compact Round Flow heat pump cassette, which features 360 degree air distribution,


inverter control and a low profile of just 260mm. Sized to fit a standard 600mm x 600mm ceiling grid, the cassettes are available with cooling/heating capacities of 3.2kW/4.0kW or 5.3kW/6.0kW and can also be used to introduce tempered fresh air. Unlike standard cassettes, the Round Flow range, which also includes higher capacity Super Slim models, uses a 360 degree round air outlet panel to provide efficient distribution of conditioned air throughout the space. The result is that less energy is consumed to reach set-point temperatures, while energy efficiency is further enhanced by the inverter control of fan speed. The Compact Round Flow cassette has been designed for ease of installation, while its low profile means it can be used in shallow ceiling voids where standard cassettes would be too deep. The 570mm x 570mm body and 647mm x 647mm panel ensure a neat and unobtrusive fit in one standard ceiling tile. Powrmaticʼs Super Slim Round Flow cassettes are available in cooling capacities from 7.1kW to 14.0kW and heating capacities from 7.6kW to 15kW.


www.powrmatic.co.uk New education gas safety


range S&S Northern has launched a comprehensive range of gas


safety equipment for use in laboratories and classrooms in UK schools, colleges and universities.


The range consists of four gas pressure proving systems to meet all laboratory requirements, alongside a carbon dioxide detector which can be used in science and food technology laboratories and standard classrooms.
