SP4LF0600 Semi-Hermetic Compressor
,SP4LF060E High Efficiency Compressor
,Semi-Hermetic Refrigeration Compressor
- Optimized Compression Design: A custom crankshaft balance design and short gas passage reduce pressure drop and vibration, maximizing compression efficiency in low-temperature refrigeration applications.
- Reliable Bearing Structure: Precision sliding bearings and thrust washers deliver smooth operation, high wear resistance, and an estimated service life of 50000 to 80000 hours.
- Integrated Safety & Motor Protection: A built-in high-sensitivity internal relief valve prevents overpressure, while the INT69VS protection module safeguards the motor against electrical overload and overheating.
- Flexible Capacity Control: Supports 100% and 50% step capacity regulation to precisely balance system output with changing refrigeration loads.
