Product Description
Refcomp SP6L2700 SP6L270E 27HP Semi Sealed Reciprocating Compressor
Product Overview
-
Three-Step Load Adaptation
Featuring 100%, 66%, and 33% energy regulation steps, this semi sealed reciprocating compressor efficiently matches partial refrigeration loads to minimize power consumption during off-peak demand. -
6-Cylinder High-Displacement Flow
Engineered as a 6-cylinder semi-hermetic reciprocating compressor, it delivers an exhaust volume of up to 135 m³/h at 60Hz through direct gas suction channels, lowering internal throttling losses. -
Heavy-Duty Bearing & Casing Construction
Constructed with a 28 bar pressure-rated casing, wear-resistant sliding bearings, and an INT69B2 motor thermal module to maintain structural integrity under low-temperature operating stress. -
Integrated Service Package
Includes 360° rotatable suction (54 mm) and exhaust (35 mm) shut-off valves, a factory 230V / 150W crankcase heater, and an internal high-density suction strainer for this refrigeration reciprocating compressor.

Frequently Asked Questions
What capacity step switching delays should be programmed into the system controller for the 100%-66%-33% regulation solenoids?
Program a minimum 30-to-60 second delay between capacity step transitions to stabilize suction pressure, prevent solenoid short-cycling, and ensure consistent crankcase oil return.
When does a low-temperature system utilizing a 4.2 dm³ oil charge require an external oil separator and reservoir system?
An external oil separator is recommended when suction lines exceed 20 meters, in multi-evaporator circuits, or where extended defrost cycles cause temporary oil migration away from the crankcase.
How can service technicians distinguish between internal safety relief valve bypass and worn valve plates during troubleshooting?
Relief valve bypass results in a rapid equalization of high-side pressure into the suction manifold accompanied by localized casing heat near the valve port, whereas worn valve plates cause gradual pressure equalization and diminished pumping capacity.
What installation precautions apply when replacing cylinder head gaskets after internal valve plate inspection?
Thoroughly clean all gasket seating surfaces, apply a thin coat of clean refrigeration oil to replacement gaskets, and torque cylinder head bolts in a crisscross sequence to preserve the 28 bar housing seal.
