06EA299 Semi Hermetic Type Compressor

The 06EA299 is a flagship 40.0 HP semi hermetic type compressor engineered for heavy-duty industrial refrigeration, large-scale cold storage facilities, process fluid cooling, and central HVAC plant racks. Powered by a robust 6-cylinder reciprocating assembly, it delivers an exceptional swept volume displacement of 140.40 m³/h at 1450 RPM. Featuring oversized internal suction gas channels designed to minimize gas turbulence and pressure loss, the unit optimizes motor winding cooling and delivers continuous high volumetric yield under demanding pressure differentials.

Engineered for fluctuating refrigeration loads, the 06EA299 integrates a suction cutoff capacity modulation system capable of stepping down output to 66% or 33%. By mechanically isolating cylinder banks rather than throttling suction gas or utilizing energy-intensive hot-gas bypass setups, the compressor maintains lower internal discharge temperatures while significantly lowering power consumption during off-peak cycles. Precision-contoured pistons match closely with cylinder head valve pockets to eliminate dead clearance volume, while Swedish steel valve reeds ensure reliable sealing and rapid gas movement under high compression ratios.

Built to endure harsh industrial operating environments, the 06EA299 features a 236 kg cast-iron block housing a 9.0 L oil crankcase. Its automatic reversible positive-displacement oil pump supplies continuous oil pressure through drilled connecting rods directly to wrist pins and main shaft bearings, protecting against bearing friction during cold starts and system load shifts. Compatible with a broad range of standard refrigerants-including R134a, R404A, R507, R407C, and R22-and backed by UL, CSA, and ISO 9002 certifications, the 06EA299 provides an enduring, energy-efficient foundation for industrial cooling skids.
