Rotary heat exchangers

Company AMALVA has been producing high-efficient rotary heat exchangers since 2003, that are being used by globally known and acknowledged air handling units producers. Our high efficiency rotary heat exchangers and their selection software conform to the requirements of EUROVENT standard. The EUROVENT certificate for the rotary heat exchangers is here.



AMALVA offers rotors with an air flow up to 60.000 m³/h and wheel’s diameter up to 3 meters.
The efficiency of rotary heat exchangers is confirmed by the results of the tests performed in Swiss and German laboratories. Thermal efficiency of the rotary heat exchangers reaches up to 85% which affects the substantial energy saving.
Rotors are produced from alternate layers of flat and corrugated 70µm aluminum foil. AMALVA offers 3 different wave heights: 2.1 mm, 1.7 mm, 1.5 mm.



Our rotors’ construction is strong and durable. Rotor wheel is strengthened by spokes which are welded on the hub and then to the rotor shell.
Particularly strong hub with reliable sealed-for-life inner bearings ensure long-lasting operation of the wheel even in the most sophisticated conditions.

Spaces between rotor and casing, and between air streams are sealled with special, long-lasting and adapted for that, sealing strip. Internal air leackage is only 1,26% – tested in Switzerland, at Lucerne University of Applied Sciences and Arts.

Several precise and original control systems have been developed for the rotors: asynchronous motor with constant speed and step drive with speed regulator.
The casing for the rotary heat exchangers is made of steel sheet. Rotary heat exchangers are easily maintained and, if necessary, simple to clean.
