The C-SBN353H8D and C-SBN353H8H are high-performance semi-hermetic piston compressors under the SANYO brand. This series utilizes a mature and stable four-cylinder piston design, specifically engineered for medium-to-large commercial and industrial refrigeration systems. Renowned for exceptional reliability, a broad operating range, and high refrigeration efficiency, they serve as the ideal power source for cold storage rooms, freezer displays, ice makers, and similar equipment.
Core Features & Advantages
1. Powerful Refrigeration & Efficient Operation
Large Displacement Design: Approximately 35.3 cm³ displacement ensures strong refrigerant throughput, capable of meeting high cooling load demands.
Optimized Scroll Technology: Features an asymmetric scroll profile design, enabling a continuous and smooth compression process with minimal internal leakage. Volumetric efficiency exceeds 95%, resulting in an excellent Energy Efficiency Ratio.
2. Rock-Solid Reliability
Robust Mechanical Structure: The core scroll set is made from high-strength special cast iron, precision-machined and treated to ensure long-term structural integrity under high pressure differentials and harsh operating conditions.
Exceptional Lubrication System: An efficient forced-feed oil circulation system ensures critical friction surfaces (bearings, scrolls) receive adequate lubrication in any operating orientation, significantly extending service life.
Excellent System Tolerance: Possesses good resistance to liquid slugging and reliable oil return, effectively mitigating shocks from system fluctuations and protecting core compressor components.
3. Low Noise & Vibration
Smooth Operation: The inherent balance of scroll compressors results in minimal torque variation and very low vibration. Operating noise is significantly reduced compared to reciprocating compressors, contributing to a better installation environment and reduced stress on system piping.
4. Wide Applicability & Easy Maintenance
Broad Operating Range: Capable of stable operation across a wide range of evaporation temperatures, from medium-temperature cold storage to low-temperature freezing, offering high application flexibility.
Simplified Maintenance: Fewer moving parts and the absence of vulnerable suction/discharge valve plates greatly reduce routine maintenance workload and costs. Built-in protection devices provide core motor protection.
