YINHUASHENG 500H professional oil return separator is a core matching accessory for vehicle transport refrigeration units. It efficiently collects and recovers refrigeration lubricating oil accumulated in low-pressure pipelines, enabling stable automatic oil return to the compressor crankcase.
This system permanently maintains a reasonable oil level inside the refrigeration system, fundamentally preventing compressor oil shortage, dry grinding, and burnout failures while greatly extending the entire cold machine service life.
