Refcomp SP4L1500 AC Semi Hermetically Sealed Compressor

The SP4L1500 features RefComp's custom-engineered dynamic crankshaft integrated with precision counterweights to ensure exceptionally balanced, low-vibration operation. Constructed with high-strength forged materials, the connecting rod and piston mechanism utilizes advanced gas-flow and friction-reduction technologies to minimize mechanical power losses. The wrist pin interface is equipped with durable wear-resistant bushings, ensuring smooth force transmission and extended mechanical lifespan during continuous heavy-load freezing duty.

To maintain structural alignment and operational stability under severe compression ratios, the drive mechanism incorporates a combination of high-precision floating sleeve bearingsand heavy-duty thrust washers. Tailored lubrication grooves deliver a constant oil film across all friction surfaces, preventing metal-to-metal contact during startup and providing the drive train with an engineered design operating life of 50000 to 80000 hours.

Equipped with solenoid-driven capacity control, the 4-cylinder compression block can step down from 100% full output to 50% partial load. This flexible power regulation enables multi-compressor racks and commercial freezing units to match fluctuating thermal loads precisely, curbing electrical consumption and preventing erratic compressor cycling during off-peak refrigeration demands.
