Quality Guarantee
THERM-CONNECT combines high-grade components, efficient control system and intelligent protective mechanisms (frost protection, overpressure protection), guaranteeing a performance that meets your needs, highest safety and efficiency as well as compliance with all relevant standards and guidelines.
THERM-CONNECT is being used throughout the year
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.
