The EXA heat recovery rotor
is complete with a rotary
heat exchanger that transfers 
heat according to the air-to-air
principle.

Airflow range: 0.2-30 m³/s,
720-108000m³/h

The rotor is available in four different versions
-NO, normal rotor
-HY, hygroscopic rotor for increased cooling
energy and humidity recovery
-NP, normal Plus rotor for higher efficiency
-HP, hygroscopic rotor in the Plus version

The rotor can be fabricated of epoxy-treated
sheet aluminium for use in aggressive
environments.
