The Refcomp SP2L0300 / SP2L030E is a 3HP (2KW) semi-hermetic reciprocating refrigeration compressor engineered for low-temperature applications. It combines integrated safety protection, a smooth-running crankshaft and connecting-rod assembly, and flexible rotatable shut-off valves to deliver dependable performance in demanding refrigeration systems.
The SP2L0300 semi-hermetic refrigeration compressor features an internal safety valve connecting the high- and low-pressure sides. Its precise opening and reset help maintain internal pressure within the intended safety range, providing additional protection against abnormal pressure conditions.
For this low-temperature reciprocating compressor, RefComp's crankshaft design promotes smooth mechanical movement, effective lubrication and reduced vibration. A wear-resistant bushing at the connecting rod's small end helps minimize friction and mechanical wear, supporting reliable operation over time.
The suction and discharge shut-off valves can rotate through 360°, allowing installers to adjust piping orientation according to actual installation requirements. This flexibility simplifies pipe alignment and makes installation more convenient, especially where equipment space is limited.
The built-in INT69B2 protection module helps protect the motor against burnout. This dedicated protection feature adds an important safeguard against abnormal operating conditions, helping reduce the risk of motor damage and unexpected downtime.

Q1: How do I select the right SP2L0300 for a low-temperature refrigeration system?
When selecting a semi-hermetic refrigeration compressor, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, ambient conditions and power supply. The SP2L0300 is a two-cylinder semi-hermetic piston compressor, and its suitability should be verified against the actual operating conditions.
Q2: What should be considered when installing the suction and discharge piping?
Check the pipe dimensions and connection directions against the refrigeration system design. The rotatable shut-off valves provide greater flexibility for pipe alignment, helping simplify installation and avoid unnecessary restrictions in piping layout.
Q3: What is the purpose of the PTC crankcase heater?
The built-in PTC crankcase heater helps maintain crankcase temperature during shutdown, reducing the risk of refrigerant migrating into the lubricating oil. Check its electrical connection and operation during installation and commissioning.
Q4: What should I do if the INT69B2 motor protection module trips?
If the semi-hermetic refrigeration compressor stops following a protection trip, inspect the power supply, phase condition, motor wiring and operating conditions. Identify and correct the underlying problem before restarting the compressor.
