Our Heat Recovery Units (HRU's) are an extremely effective and low-cost way of reducing the heating or cooling loads on the treatment of process air and air conditioning systems.
A reduced heating or cooling load means lower energy bills and reduced carbon emissions.
HRU's use the exhaust air to pre-heat or pre-cool the incoming supply air, without the two air streams ever mixing.
A HRU has no moving parts and uses no energy itself. Payback periods are usually very quick.
As an option, we can supply the heat exchanger cores on their own for others to fit within their own enclosures - see air to air heat exchangers.
Energy recovery typically 50 - 85%, depending upon operating conditions.
