Product Description
Refcomp SP4LF0600 SP4LF060E Low Temp Semi Hermetic Compressor
Product Overview
Heavy-duty semi-hermetic compressor engineered for low-temperature applications with robust construction and advanced performance features.
- Direct Gas Flow & Pressure Shell: Heavy-duty housing rated up to 28 bar with direct-path gas suction channels to minimize pressure losses and maintain high volumetric efficiency in low-temperature conditions.
- Balanced Heavy-Duty Drive Mechanism: Features dynamically balanced crankshaft, wear-resistant sleeve bearings, optimized connecting rods, and internal safety valve for low vibration and stable long-term operation.
- Broad System & Grid Adaptability: Engineered for multi-refrigerant operation (R22, R134a, R404A, R407C, R507) with compatibility for both 400V/50Hz and 460V/60Hz industrial power networks.
- Accessible Components & Protection Package:
- Factory 230V / 220W crankcase heater for oil protection during off-cycles
- INT69B2 motor thermal overload protection module
- 360° rotatable suction (28 mm) and exhaust (22 mm) shut-off valves
- Accessible internal suction gas filter

Frequently Asked Questions
What technical data should be provided to verify selection for this semi hermetic type compressor?
Technical evaluation requires providing target evaporating and condensing temperatures, required cooling capacity, operating refrigerant type, power supply specifications, and application details.
What piping insulation and layout practices are recommended during system integration?
Ensure suction lines connected to the 28 mm valve are properly insulated to minimize superheat gain, and install line traps to guarantee efficient oil return during part-load (50%) operation.
What diagnostic steps should be taken if the INT69B2 module trips during operation?
Inspect motor winding connections, measure supply voltage phase balance, confirm current does not exceed the 16 A maximum limit, and check for proper suction gas cooling.
Can additional head cooling or oil protection accessories be specified for this model?
Yes, supplementary cylinder head cooling fans and oil differential pressure switches can be integrated depending on the specific low-temperature evaporating range.
