Heat Recovery Systems Now Available from Airtherm Engineering Ltd


Heat Recovery systems are playing a increasingly important role in modern building design. An effective building ventilation solution has become critical as a result of increased levels of insulation and air tightness in commercial buildings. Factors such as ever increasing energy costs, modern construction methods and building regulations have ultimately led to poor indoor climates that can cause health problems for occupants and damaging long term effects to the fabric of a building.

Our Duplexvent commercial heat recovery units are designed to save your business energy and improve the indoor air quality. These units provide ventilation and heat recovery (for commercial and industrial areas) by using polypropylene exchangers which recover heat from the transfer of warm air to cold air via exchangers with high conductivity and performance.

Benefits of Heat Recovery
  • Saves energy by reducing heating costs
  • Extracts airborne pollutants that can cause allergies and asthma
  • Constantly refreshes the internal atmosphere
  • Removes condensation and humidity
  • Supplies warmed, filtered air to living and working spaces
  • Up to 94% heat recovery
  • SAP Appendix Q eligible models
  • Helps reduce a buildings carbon footprint
  • Meets building regulations, Approved document F, April 2010 (MVHR

Heat recovery technology works by preheating incoming cool supply air by warming it with the outgoing exhaust air. In this way exhausted air transfers most of its heat to the supply air in a highly efficient heat recovery exchanger before being exhausted (at no time do the airstreams mix). 

In Practice
Stale air, contaminated with humidity, toxins and smells is extracted via outlet grilles from the kitchen, bathroom and toilet areas. These outlet grilles allow a constant or demand oriented air flow volume to be extracted.
BREEAM (BRE Environmental Assessment Method) Our heat recovery units help buildings to be assessed for the BREEAM standard (BRE Environmental Assessment Method) - the leading and most widely used environmental assessment method for new buildings.
