The YINHUASHENG 600-II professional oil return separator is an exclusive matching core accessory for HUASHENG THERMO vehicle refrigeration units. It efficiently collects and recovers lubricating oil accumulated in high-pressure refrigeration pipelines, enabling stable automatic oil return to the compressor crankcase.

This maintains proper oil levels throughout the refrigeration system, preventing compressor dry grinding, oil shortage burnout, and abnormal wear failures while significantly extending the service life of truck cold chain units. Featuring standard inlet/outlet/oil return flow direction marks, it perfectly adapts to long-distance bumpy road conditions and harsh cold chain working environments.

• Exclusive customized matching for YINHUASHENG full series HT/EV/DZ/ZB/DTE transport refrigeration units, ensuring perfect fit and stable performance
• Precision internal separation structure efficiently recycles scattered refrigeration oil in system pipelines, reducing oil waste and maintaining system efficiency
• Standard clear flow direction marks completely avoid wrong pipeline reverse connection during installation, saving installation time and reducing maintenance costs
• Reinforced high-pressure cylinder body ensures stable operation under extreme high & low temperature cold chain environments, adapting to various harsh working conditions
• Built-in integrated fixing bracket requires no extra installation accessories for quick plug-and-play replacement, improving maintenance efficiency
• High-density anti-corrosion paint coating provides ultra-long service life in outdoor humid low-temperature vehicle working conditions, reducing replacement frequency

Suitable for roof-mounted non-independent engine-driven refrigeration units, EV electric parking backup cooling systems, HT series heavy-duty reefer maintenance replacement, and refrigerated van cold chain suction line oil recovery matching parts.
