The compressors are then mechanically run on air test rigs to confirm that volumetric efficiency, absorbed power, oil flows and vibration levels meet the stringent acceptance standards. Additionally, all oil injected compressors are tested with air under water following final assembly. The casing components are hydraulically tested to a minimum of 1.5 times maximum operating pressure to ensure integrity. COMPRESSOR ASSEMBLY AND TESTINGĪll oil injected twin screw compressors are factory assembled by skilled engineers. Cast iron is the normally casing material alternative casing materials are spheroidal graphite iron or various grades of steel. CASINGSĬasings are precision machined from castings using state of the art horizontal machining centres to achieve the essential close tolerances.
