DC12V-24V COMPRESSOR R134a ZH45G

ZH45G DC 12V/24V R134a Compressor
1. Dual DC Voltage - 12V / 24V

The ZH45G DC compressor is designed to operate with both 12V and 24V DC power supplies, providing flexible compatibility with different refrigeration systems. It is suitable for vehicle refrigeration, battery-powered systems, mobile refrigeration equipment, RVs, boats and other DC-powered applications.

2. 4.5 cm Displacement & R134a Refrigerant

The ZH45G features a 4.5 cm displacement and is designed for use with R134a refrigerant. The larger displacement compared with the ZH25G and ZH35G provides higher refrigeration capacity, making it suitable for refrigeration systems requiring stronger cooling performance.

3. Variable Operating Speed - 2,000-3,500 RPM

The compressor supports operating speeds of 2,000, 2,500, 3,000 and 3,500 RPM, allowing the refrigeration system to match compressor output with different cooling requirements. Cooling capacity ranges from 74W at 2,000 RPM to 135W at 3,500 RPM.

4. High-Efficiency Refrigeration Performance

According to the supplied technical data, the ZH45G achieves a COP of 1.35 W/W. At 3,000 RPM, it provides approximately 118W cooling capacity (402.6 Btu/hr), with current consumption of approximately 7.1A at 12V or 3.5A at 24V.

5. Suitable for Mobile & Compact Refrigeration Systems

With its 4.5 cm displacement, 12V/24V DC operation, R134a refrigerant compatibility and FC (Forced Convection) cooling, the ZH45G is suitable for car refrigerators, portable refrigeration units, small freezers, RV refrigeration systems, marine refrigeration equipment, battery-powered refrigeration and other compact refrigeration applications.
