HRE-PremAIR counterflow heat exchangers are designed for Alnor PremAIR series recuperators and are available in two versions: thermal and enthalpy.
The thermal models HRE-PremAIR-P, HRE-PremAIR-E and HRE-PremAIR-A have fins made of PET or aluminium and enable heat recovery of up to 93%. The aluminium or aluminium and acid-resistant steel housing ensures lightness, rigidity, tightness and resistance of the structure to the operating conditions of the device.
HRE-PremAIR-E enthalpy exchangers, on the other hand, recover not only heat energy but also moisture thanks to polymer membrane fins that allow water vapour to pass through while preventing the mixing of air streams. They are particularly recommended in colder climates, where they help maintain optimal humidity in the building. All exchangers can be cleaned independently using warm water with a mild detergent (pH 6–8).
