recuperatore di calore HRW

HRW is a heat recovery ventilation unit with a high efficiency heat recovery unit, air treatment section for dehumidification, cooling and heating.

It combines the advantages of air exchange with an hidronic integration system that uses an additional recirculation network.

It is therefore able to meet the cooling requirements even on the residential buildings with high external loads.

It can be powered by heat pumps eHPoca and 3in1, generic heat generators and chillers.

The unit is composed of a monoblock including each component for correct operation and allows operation with wide outdoor temperature ranges.

GENERAL FEATURES

struttura-hrp-domoStructure
Panels are performed of double sandwich panel, with an externally painted finishing and galvanized inside the unit.
Self-supporting perimeter frame in galvanized metal sheeting. The insulation of the panels is realized of a high-performance insulation material with a thickness of 20 mm and a 6 mm thick adhesive polyethylene insulation material. Choice of materials with elevated thermal and acoustic insulation characteristics.
