Commercial Semi Hermetic Refrigeration Compressor 06DR820 for Cold Storage

The 06DR820 is a 6.5HP 4-cylinder semi hermetic refrigeration compressor engineered for commercial cold rooms, food storage facilities, and supermarket display systems. Featuring optimized gas flow passages and precision Swedish steel valve plates, it delivers high volumetric efficiency while maintaining steady evaporating temperatures. Cold chain operators can lower daily power consumption while maintaining strict temperature control for perishable inventory.

High ambient temperatures and heavy continuous loads can lead to premature motor burnout and lubrication failure during initial startup. To prevent these field issues, this semi hermetic refrigeration compressor incorporates a heavy-duty motor with high-grade electrical insulation and an automated bidirectional oil pump. Paired with an expanded crankcase oil sump, it ensures positive lubrication even during heavy refrigerant migration, protecting critical bearing journals against wear.

Furthermore, this semi hermetic refrigeration compressor features an integrated suction cutoff unloading system that provides 50% capacity modulation, running at significantly lower discharge temperatures than hot-gas bypass designs. Compatible with multiple HFC refrigerants including R404A and R134a, it offers system integrators a versatile and reliable solution for modern cooling projects.
