Reznor moves into heat recovery
Plate heat exchangers and thermal wheels made by Klingenburg of Germany are being marketed in the UK by Reznor as an approach to reducing the energy needed for heating buildings. Recent innovations by Klingenburg provide counterflow plate heat exchangers with heat-recovery efficiencies of up to 85% for heating and ventilation applications. When applied to fresh-air input units, such high-efficiency heat recovery can eliminate the need for additional LPHW or electric heating. coils. Thermal wheels are available in diameters up to 6 m. Andrew Patch of Reznor explains, ‘Recognising that ventilation loss forms the major part of energy consumption in HVAC systems, it is essential that heat recovery is applied wherever possible. The Klingenburg range will complement our existing offering, both in terms of quality and energy efficiency. Air-quality standards must be maintained, but at the same time we need to recover as much heat as possible from the exhaust air and re-use it. The increased air capacity and high energy efficiency of the Klingenburg heat-recovery range offers designers, consultants and manufacturers a new option in reducing carbon emissions and ongoing running costs.’For more information on this story, click here:Dec 2007, 161
