Frick GDSH Compressor Service Repair and Overhaul












The GDSH series, is used in typical refrigeration and natural gas applications up to 400 psig (27.6 bar). It is also offered with optional nodular iron pressure retaining housings up to 600 psig (41.4 bar). The PDSH series, with cast steel housings, is used in gas processing or industrial refrigeration in chemical and petrochemical applications up to 600 psig (41.4 bar). The compressors are direct drive at speeds from 600 to 4500 rpm for rotor sizes up to 9.173 in. (233 mm) or 600 to 3600 rpm for larger sizes. Power ratings of the series range from 250 to 6000 hp (186 to 4474 kW).

Frick compressors use 100% anti-friction bearings. Cylindrical roller bearings handle radial loads, and angular contact bearings, aided by a balance piston, absorb thrust loads. Roller bearings maintain accurate rotor positioning to minimize internal leakage and inefficiency. Frick TDSH, GDSH, RWB ii, RWF, RDB, SGC, SGCH, and SGCB bare screw compressors are designed to compress a variety of gases for quality solutions in refrigeration, water chilling, wellhead compression, gas gathering, and vapor recovery. The antifriction bearings minimize frictional power losses. Injected oil to lubricate the bearings, balance piston, seal and fill any leakage paths between and around the rotors to prevent internal gas recirculation losses. Oil injection also minimizes noise and vibration, keeping the compressor cool by absorbing much of the heat from compression. System differential pressure is normally sufficient for supplying oil to the bearings.

The Frick Rotary Screw Compressor features advanced technology and inherent reliability in its simplicity. Fewer moving parts and simple rotary motion means less maintenance, lower noise and vibration levels, and of course, lower total repair costs, saving you money time and time again. Compressor housings are machined to provide static oil reservoirs for the bearings. Therefore, Frick compressors can run in most applications without an oil pump. A steeples hydraulic or manually actuated slide valve moves axially along the rotor mesh line to provide unloading. Unloaded gas is internally bypassed back to suction before compression has begun, allowing the compressor to efficiently accommodate system requirements. A hydraulically actuated slide stop adjusts slide valve length to optimize internal discharge pressure. This matches compressor volume ratio (Vi) to system pressure ratio and eliminates the power penalties associated with typical screw compressor under- or over-compression. Vi is infinitely variable from 5.0 to 2.2 and also 3.0 to 1.7 on some models.
