SIBERIA Compressor For Refrigerator

Low back pressure characteristics: The R134a compressor produced by our company stands out for its low back pressure design and has a wide evaporation temperature range (-35℃ to 0℃), which can not only fully meet the use requirements of low back pressure refrigeration equipment (-35℃ to -15℃) such as household refrigerators and freezers, but also pay special attention to the stringent requirements of light commercial refrigeration equipment (such as commercial freezers, order cabinets, display cabinets, etc.) in the range of -20℃ to 0℃.

SIBERIA hermetic refrigerator compressor supports R134a and R600a refrigerants with evaporation temperature 35℃~0℃. Featuring lowvoltage startup and hightemperature resistance, it fits regions with unstable power supply and hot climate. It delivers high startingtorque and quick restart performance. R600a model reaches COP 1.51.7 with low noise. Suitable for household fridges, freezers and lightcommercial display cabinets for OEM and replacement service.

Core Advantages

Low voltage startup: normal operation down to 165V for unstablegrid areas Hightemperature endurance: works under ambient temp up to 43℃, can reach 50℃ with proper system matching Wide evaporation range 35℃~0℃, for household & lightcommercial refrigeration High startingtorque & quick restart for frequent onoff cycles R600a variant with high COP and low noise

Notes

Use matched refrigerant and voltage. Cool compressor during welding to avoid internal damage. Ensure good ventilation for heat dissipation. Store in dry place; protect tube ports against moisture ingress.

Low-voltage starting capability: The compressor can start and operate normally at a power supply voltage as low as 165V. Compared with the 187V to 242V voltage range required by general compressors, this feature makes it particularly suitable for countries and regions with unstable or low power supply voltage.
High-temperature environment resistance: At an ambient temperature of up to 43℃, the condensing pressure of the compressor can reach 18Kgf/cm² and continue to work, far exceeding the 16Kgf/cm² limit of general compressors. Through reasonable matching of the refrigeration system (such as increasing air circulation, adding condensers, etc.), its working environment temperature can be further increased to 50°C, which is especially suitable for use in countries with high-temperature environments.
High starting torque motor (HST): The use of large-size silicon steel sheets, high stacking thickness design, and aluminum alloy motors gives the compressor a strong starting torque. Although this leads to a larger compressor housing size and increased costs, it ensures good performance.
Fast restart mechanism (hammer starter): With the ability to restart repeatedly within a short interval, it is very suitable for commercial refrigeration equipment that requires frequent switching on and off, such as refrigerators and freezers, and scenarios in the medical field that have strict requirements on room temperature fluctuations.
R600a refrigeration compressor: Known for its good low-temperature performance, low noise level, and energy efficiency ratio (COP) of up to 1.5~1.7 (W/W), it provides an efficient and quiet solution for refrigeration systems.
