SERIES OF SERIE 180-300 kW Reciprocating Refrigerant Compressors

BENEFITS PUNTI DI FORZA TRADITION AND INNOVATION TRADIZIONE E INNOVAZIONE These compressors are designed to operate at 1450 and 1750 rpm. They cover a capacity range from 180 to 300 kW: four models for open version. Our methods of design and construction, together with the strictest manufacturing tests, have enabled us to assure all the following: □ High performance, resulting from volumetric and compression efficiency. □ High reliability, long-working life, efficient service and low operation costs. □ Quiet running: careful balancing of the moving mechanical parts ensures a minimum of...

FEATURES CARATTERISTICHE Technical data Caratteristiche tecniche Casting: casting is constructed from high-tensile, closegrained, cast iron with stress relieving heat treatment. Carcassa: le fusioni sono in ghisa di elevata qualità ed alta resistenza, sottoposte a trattamento di distensione. Crankshaft: forget steel, statically and dynamically balanced. Albero a gomiti: in acciaio forgiato, staticamente e dinamicamente bilanciato. Capacity control: this consists of a capacity control system which controls compressor capacity by activation an unloading mechanism set on cylinders. It is oil...

EXTENT OF DELIVERY FORNITURA Capacity control The OF series compressors may be delivered together with a certain number of capacity control steps according to the following logic. The capacity control consists of a capacity control system which controls compressor capacity by activation an unloading mechanism set on cylinders. It is oil pressure activated through solenoid valves (externally mounted) witch turn on and off the oil pressure supply to load or unload the cylinders in response to an external thermostat (provided by others). Compressor always starts at minimum capacity, meaning...

EXTENT OF DELIVERY FORNITURA “HFC” refrigerants & “POE” lubricants The compressors can operate with both HCFC (R22 chlorinated refrigerant) and HFC (R134a chlorine-free refrigerant). Only the charged lubricant varies according to the refrigerant type. Polyol ester oils (POE) are recommended with chlorinefree refrigerants (HFC). However, the high degree of hygroscopicity of the POE oils demands for particular cautions: these oils must not come in contact with air and the moisture content in the circuit has to be maintained, as a general rule, under 50 ppm. I compressori sono costruiti in...
