DEHDehumidification unit and air change with heat recoveryresidential ventilation unit wiyh heat recovery and dehumidification in combination with radiant cooling systems- Ceiling installation- Horizontal configuration
Range: n. 2 models:- DEH-1 with air flow rate from 300 to 150 m³ / h- DEH-2 with air flow rate from 500 to 250 m³ / h
DESCRIPTION- Aluzinc self-supporting panels, sides in double panels insulated with foam polyurethane, 23 mm thick, top and bottom sheet single (insulated),
- Aluzinc drip tray condensation- Basic configuration: electronic microprocessor and electrical cabinet pre-wired on the machine (plug-nplay)- Configuration with CO2 probe for automatic control of the flow of fresh air (optional)- Refrigerant circuit with hermetic compressor that uses refrigerant R134A
ELECTRIC FANS- Electronic motors Fan EC plug fans 230V-1-50 / 60Hz high efficiency (ErP-2015)
HEAT EXCHANGER- Polypropylene exchanger counterflow high efficiency. DEH is also available in enthalpy version to recover the latent heat (humidity) in
addition to the sensible heat (temperature).
FILTERS- Filters: air extraction / renewal / recirculation: class Coarse 65% (G4) / ePM1 70% (F7) / Coarse 65% (G4) (EN 779)
