Howden WRV 321 Components:

ROTORS
All rotors for Howden twin screw compressors are machined from solid bar or forgings on highly accurate cutting machinery. The standard material is carbon steel, but forgings or special alloys can be used for more arduous applications. Following machining and balancing to ISO standards, male and female rotors are paired for assembly to ensure the ideal combination for maximum efficiency.

CASINGS
Casings are precision machined from castings using state of the art horizontal machining centres to achieve the essential close tolerances. Cast iron is the normally casing material; alternative casing materials are spheroidal graphite iron or various grades of steel.

COMPRESSOR ASSEMBLY AND TESTING
All oil injected twin screw compressors are factory assembled by skilled engineers. The casing components are hydraulically tested to a minimum of 1.5 times maximum operating pressure to ensure integrity. Additionally, all oil injected compressors are tested with air under water following final assembly. 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.
