Refcomp SP6L2700 SP6L270E Reciprocating Semi Hermetic Compressor For Chiller

To guarantee dependable operation in heavy-duty commercial environments, the SP6L2700 is factory-fitted with an advanced INT6932 motor protection module. Interfaced directly with PTC sensors embedded in the motor stator, this module continuously monitors winding temperatures. It instantly cuts the control circuit during thermal overload, locked rotor scenarios, or severe voltage fluctuations, preventing costly motor burnout and shielding the compressor.

Engineered for rugged industrial use, the compressor features a heavy-duty cast-iron casing rated for 28-bar working pressure. The internal architecture is optimized with wide, low-resistance suction gas passages that significantly reduce suction superheat loss. Furthermore, an internal high-pressure safety relief valve safeguards the casing and gaskets by bypassing gas back to the suction side during dangerous over-pressurization events.

Designed to power a massive 6-cylinder block, the high-efficiency 27 HP stator motor is engineered to support dual-voltage, multi-frequency grids while minimizing electrical stress. Utilizing a PW or Star-Delta (Y/Δ) starting configuration, the system effectively stages power energization, cutting initial starting inrush current. This prevents severe voltage drops on the jobsite grid, stabilizes electrical switchgear, and extends the lifespan of contactors.
