06EM199 35HP Semi Sealed Reciprocating Compressor

Engineered for demanding commercial refrigeration, process cooling, and large-scale HVAC systems, the 06EM199 semi sealed reciprocating compressor delivers a 35 HP nominal rating with a 140.4 m³/h volumetric displacement at 1450 rpm. Built on a robust 6-cylinder platform, it features high-flow Swedish steel valve plates and contoured piston tops designed to match valve plate profiles. This design drastically reduces cylinder clearance volume to maximize volumetric efficiency across medium- and low-temperature applications.

To lower power consumption during partial-load conditions, the 06EM199 incorporates a suction cutoff energy modulation system that shuts off suction to cylinder pairs for efficient 66% load operation. This method provides higher operating efficiency and running temperatures significantly lower than conventional hot gas bypass setups. The compressor supports broad refrigerant compatibility, working with modern HFCs (R404A, R507, R134a, R407A, R407C) and traditional refrigerants using POE lubricants.

Equipped with an automatic bidirectional positive-displacement oil pump and an oversized 9-liter oil sump, the 06EM199 maintains constant positive oil pressure even during sudden start-up oil dilution or migration. Steel-backed Babbitt main bearings absorb high mechanical stresses, while enlarged suction gas passages utilize return gas to cool motor windings. Integrated discharge temperature protectors, internal suction strainers, and wide 50Hz/60Hz voltage tolerances ensure dependable operation across diverse power infrastructure.
