Carlyle 06EM175 25HP Industrial Semi Sealed Reciprocating Compressor for

The 06EM175 semi sealed reciprocating compressor is a 25 HP, 6-cylinder heavy-duty unit designed for commercial refrigeration, process cooling, and HVAC chiller applications. Engineered with low-stress Swedish steel valve reeds and generous porting, the valve design optimizes gas flow to deliver maximum volumetric efficiency. Contoured piston tops fit tightly within suction valve recesses to reduce dead clearance volume, while connecting rods with internal oil passages supply constant pressure lubrication directly to bearing surfaces.

To guarantee instantaneous oil pressure upon startup, the compressor incorporates an automatic reversible positive-displacement vane oil pump. Suitable for HFC refrigerants (R134a, R404A, R507, R407A, R407C) with POE oils, as well as conventional refrigerants (R22, R12, R502), this semi sealed reciprocating compressor features an oversized crankcase oil sump. The enlarged sump retains a substantial oil reserve, ensuring liquid refrigerant washback on startup does not drop the oil level below safe operating limits.

Featuring oversized suction gas channels, incoming suction gas passes directly across the motor windings to dissipate heat and maintain low winding temperatures during continuous operation. The 6-cylinder block supports a 66% suction cutoff energy regulation system that cuts gas intake to two cylinders simultaneously, offering far greater thermal efficiency than traditional hot gas bypass circuits. Every 06EM175 semi sealed reciprocating compressor carries UL, CSA, and ISO 9002 quality approvals, with main bearings made from steel-backed aluminum or tin-based Babbitt alloy for superior wear resistance.

We specialize in supplying reciprocating compressors, semi-hermetic compressors, scroll compressors, rotary compressors, and screw compressors, as well as cold storage equipment, quick-freezing equipment, and ice-making machinery. Supporting full OEM and ODM customization services, Coolstart serves commercial clients across the United States, Russia, the United Arab Emirates, Saudi Arabia, the United Kingdom, and global markets. Backed by strong technical capability and cost-effective product solutions, we build reliable, long-term partnerships with industrial B2B buyers worldwide.

The 25 HP 06EM175 model is designed for high, medium, and low-temperature applications in commercial refrigeration, air conditioning, and process cooling, operating with HFC refrigerants (R134a, R404A, R507, R407A, R407C) and traditional refrigerants (R22, R12, R502).

The compressor uses a suction cutoff unloading system that cuts off suction intake to two cylinders simultaneously. This provides an energy-efficient partial-load option (66% capacity) while maintaining lower operating temperatures compared to hot gas bypass methods.

An automatic reversible positive-displacement vane pump rapidly generates oil pressure, while an oversized crankcase oil sump prevents liquid refrigerant dilution from reducing lubricant levels below safe thresholds.
