The inherent high-pressure capability of the single screw compressor has been enhanced, allowing full acceptance of the highest operating discharge pressure from the host system, in excess of 180 psig (13.2 atm). Reliability has been a key initiative during the engineering of this new compressor line. Testing at multiple installations in North and South America and Europe has confirmed the performance reliability of the high pressure, single-screw compressor.
