    – 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
