Air chiller ENRF

liquidwaterglycol water

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
