Fresh Air / Exhaust Air Systems are incorporated into residential as well as commercial buildings in order to ensure proper air cycling as per ventilation requirements. The Fresh Air / Exhaust Air calculation is done either based on the occupancy of the room, purpose of use or else the required Air Cycle rate.
We have successfully completed and handed over several projects which included FAHU with and without Heat Recovery Wheel in many of our projects. The Heat Recovery Wheel system was invented to save energy by transferring heat from the hot Fresh Air to the expelled Exhaust Air.
Throughout our projects, we have installed and commissioned both Chilled Water type and DX Type FAHU’s depending on requirements. By implementing an FAHU, with Supply and Return, we are able to control the whole ventilation requirements for an entire building with precise control on the Supply Air humditiy and temperatures.
