Free-cooling

– The chiller is equipped with a “FREE-COOLING” system to save energy by using outdoor air when weather conditions permit.

The regulation system compares the outdoor temperature, the glycol water temperature at the “free-cooling” battery input, and the “free-cooling” (Delta) setpoint, in order to support total or partial chilling using ambient air, thereby reducing the use of refrigeration compressors and therefore the electric energy consumed.

Compressor: Scroll type

Evaporator : Coaxial exchanger immersion type (ENRF 22 to 100) or multi-tubular type (ENRF 130 to 370)

Air condenser: Battery of copper tubes and aluminium fins

Fan: Helical type

Refrigeration circuit:
Thermostatic pressure-reducing valve
Dehydrating filter
Liquid indicator
Liquid solenoid valve
High-pressure safety switch
Low-pressure switch
High-pressure manometers & Low pressure manometers

Complete steel hydraulic circuit including:
Steel pressurised buffer volume (stainless steel as optional extra)
2.1 bar centrifugal pump
Flow controller for evaporator protection
Water manometer

Regulation : CAREL µC² microprocessor, with digital display
