Heat transfer in winter and cold transfer in summer

WOLF hydraulic modules make it possible. The air inlet and outlet registers separated from each other are connected hydraulically by a water-glycol mixture, which is transport-ed by an energetically optimized high-pressure centrifugal pump.

The high-performance registers

working with high counterflow exposure and a reactivation of the single heat transfer steps provide maximum efficiency. Depending on type and requirements, our hydraulic modules can be installed flexibly as separate housing cube or in the ventilation unit.
