The solid construction of the CRR heat exchanger creates a rigid self-supporting cassette and ensures proper mounting for the rotating mechanism. The rotor is suitably reinforced, depending on the diameter of the wheel.
The most important features
Wide range of rotor diameters 300-2500 mm in 50 mm steps. Rotor length 200 mm or 250 mm. Louver spacing 14 mm or 16 mm.
Control with the function of smooth regulation of the rotational speed of the rotor - by a motoreducer system with a frequency converter. Location of the drive on the service side at the bottom or top of the casing. Belt tension adjustment mechanism as standard.
The use of a hygroscopic heat exchanger reduces the demand for cooling the supplied air and reduces the size of the cooling unit. In summer, the supply air is not only pre-cooled but also dehumidified at the same time.
Due to the transfer of more moisture from the exhaust air to the supply air and a small amount of condensate from the exhaust air, regenerative exchangers can be used in ventilation systems with low outdoor air temperatures, and at the same time move the freezing point to lower values.
Aluminium sheet with a hygroscopic coating, from which the rotor in the CRR-H* hygroscopic heat exchanger version is made, allows for greater recovery of moisture from the exhaust air and contributes to the improvement of the quality of the supply air.
* Implementation in 2022.
Compact design slightly larger than the rotor diameter dimension. The depth dimension ensures minimization of the length dimensions of the air handling unit section.
Possibilities of purchasing of the CRR heat exchanger with or without a casing cassette. Rinsing chamber delivered for self-assembly. Rib dividing the casing vertically or horizontally.
