Refcomp SP4HF1000 SP4HF100E 10HP Semi Hermetic Reciprocating Compressor

• Advanced Crankshaft, Connecting Rod & Piston Assembly: Precision-engineered crankshaft with counterweights for optimal dynamic balance and low vibration. High-strength connecting rod and piston setup lowers clearance volume, improves gas compression efficiency, and prolongs component operational life.
• High-Reliability Sliding Bearings: Engineered to withstand heavy-duty thermal loads with high-precision hydrodynamic sliding bearings and thrust washers. Minimizes radial and axial frictional wear, prevents scoring, and delivers exceptional operational stability with estimated bearing design life of 50,000 to 80,000 hours.
• High-Efficiency Motor Design: Custom electrical stator and rotor structure supporting Part-Winding (PW) or Direct-On-Line (DOL) starting configurations. Continuously cooled by low-temperature suction gas flowing through internal motor passages, lowering thermal stress, reducing startup power surges, and maintaining high operating efficiency across multi-refrigerant applications.
