Description
APPLICATION:
Air ; water heat pump for outdoor installation. Suitable for multi-family houses and commercial applications due to up to 24 kW as a single device and up to 144 kW in cascade. The housing construction enables a flexible installation - even in the open.
FEATURES/COMFORT:
Optimized noise reduction through enclosed cooling circuit and decoupled compressors. The evaporator's large leaf gap allows for low air resistance and, in conjunction with the modulating fan, provides a low sound power level. The heat pump controller (accessory) together with the ISG (optional accessory) enables a control of the system in the home network or with a mobile terminal. With integrated heat quantity and current counting via cold loop data. Fault messages can be processed externally via a 230 V signal. If required, integration into building automation can be realized via a software extension. The cooling circuit is hermetically closed, tested for leaks at the factory and filled with safety refrigerant R407C.
EFFICIENCY:
Demand-dependant and energy-efficient circulation reversal defrosting. The condensate sump is heated by the cooling circuit to allow efficient defrosting.
INSTALLATION:
The metal housing is corrosion-protected, made of hot-dip galvanized and powder-coated steel sheet and is enameled in alpine white.
