HEAT RECOVERY:
Enthalpic counter-current entirely made of plastic material.
STRUCTURE:
self-supporting structure in pre-painted steel with thermal and acoustic insulation.
FANS:
plug fan with EC Brushless motor.
FILTERS:
the units are equipped as standard with G4 efficiency filter cells.
CONTROLS:
HC CTR COLOR: control for unit setting. Operational functions from external system. HC CTR PLUS: unit setting control with humidity probe included. In the case of only control with HC CTR PLUS, the positive evaluation of the thermotechnical consultant is imperative. Unit operating only with chilled water supply. Dedicated hydronic chilled water circuit is highly recommended.
