Quiet fans

Quiet and energy-saving centrifugal fans from EBM-PAPST, a leader among fan manufacturers.

Counter-flow exchanger

Counter-flow exchanger from CORE, a leading manufacturer on the market, characterized by high heat recovery efficiency of up to 95%.

Summer cassette*

When placed in the AHU, the summer cassette eliminates the function of a heat exchanger. It is mainly used in the summer, when the outside temperature is close to the target temperature in the building and heat recovery is unnecessary or even undesirable.

Modulating pre-heater*

500 W pre-heater for even greater control of the exchanger against freezing.

Inspection hatch - 30 mm insulation

Thanks to the use of a thick layer of insulation, the air handling unit is protected against condensation of water vapor in the recuperator, and heat losses are virtually eliminated.
