The duct-mounted cooler-heater is designed for domestic ventilation systems, enabling the cooling of supply air in summer and heating in winter. The unit features a housing made of galvanized steel, insulated with a 24mm rubber mat. Inside, there is a 6-row aluminum heat exchanger with copper tubes and an integrated aluminum condensate tray. The design ensures easy access to the exchanger for maintenance and allows for reversible mounting (left/right side). Connection spigots with EPDM rubber gaskets enable mounting on feet or suspension from the ceiling. The unit can cooperate with PremAIR, SlimAIR, and MinistAIR recuperators and is available with an optional ISO Coarse 70% (G4) air filter.
