GRW
Information request Download our catalogue |Info
The Water Cooling Units of the “GRW“ range are water condensed monobloc groups. They are manufactured in two different versions: with a built-in tank or an external reservoir (V). These chillers are available in a modular version (C) allowing also for additional units of a similar or different cooling capacity at a later time.
The GRW range is especially suitable for cooling moulds of plastics working machines; they may also be used in other industrial processes.
Key features:
• R407C ecological refrigerant
• Rotating Scroll motor-compressor groups that have up to 6 Coefficient of Performance (COP)
• Compressors start-up automatic rotation
• Copper shell and tube condenser or stainless steel brazed plate condenser, provided with high -efficiency water-gas exchange
• Molecular sieves dehydrating filter
• Liquid level sightglass
• Solenoid valve
• Expansion valve
• Flow switch for water flow control
• Safety pressure switches for high and low gas pressure
• Water level pressure switch
• Copper shell and tube evaporator or stainless steel brazed plate evaporator, provided with high -efficiency water-gas exchange
• Shock absorbers to limit the transmission of vibrations generated by compressors
• Water re-circulating centrifugal electropump with non return valve (spare pump available on request)
• Manual by-pass valve, or in alternative automatic proportional by-pass valve if required
• Built-in reservoir, or in alternative external reservoir for “V“ version
• Water fill-up group for built-in reservoir version
• Control panel, with IP55 protection, complete with a microprocessor based electronic instrumentation for the set-up and display of the working temperature (remote version also available)
• Painted standard frame or galvanized (Z) frame for outdoor installation without roof
The Cooling Units of the “GRW“ range can be coupled with special Air Blast Coolers of the “BR“ range for cooling of condensation circuits and obtaining the Economising Cooling Systems of the “RBW“ range. Industrial Frigo long term experience in the industrial cooling field, has enabled us to design and manufacture a wide range of special purpose built equipment to meet customers specific requirements.
