Water Chillers KRISTAL Series
KRISTAL is part of the FORTYchiller family, a range created for custom air conditioning.
It is a hydronic monoblock with reversible heat pump for external installation, extremely compact and quiet. Especially suitable for residential applications, it pays special attention to reducing noise levels. All units are equipped with a water circulation pump and an inertial accumulation tank. The basic version includes modulation control of the ventilation, the safety flow switch for water circulation and the evaporator anti-ice resistance.
Compact
They are supplied with complete wiring and assembled in a single monoblock covered with panels. Only hydraulic and electrical connections need to be made.
Silent
Equipped with rotary or scroll compressor and low-speed fans that guarantee a reduced noise level in accordance with current regulations.
Reliable
The functions and safety devices are automatically managed by a Mach1 microprocessor, which allows the recording of multiple alarms.
