Semi-Hermetic Reciprocating Refrigeration Compressor
Model: YBF6J-16.2DS ~ YBF6F-30.2DS
The YBF6J-16.2DS to YBF6F-30.2DS series are large-capacity semi-hermetic 6-cylinder reciprocating refrigeration compressors, engineered for high-load, continuous-duty industrial refrigeration systems. Featuring a precision cast iron body, large-bore suction/discharge pipe connections, and an integrated motor protection module, this series delivers stable, efficient performance across a wide range of industrial cooling and freezing applications.
6-Cylinder Heavy-Duty Configuration | The six-cylinder reciprocating mechanism delivers high volumetric efficiency and sustained refrigeration capacity, making it ideal for large cold storage, blast freezing, and industrial process cooling with demanding continuous-duty requirements.
Large-Bore Pipe Connection | Oversized suction and discharge ports with large-bore flexible rubber hose fittings minimize flow resistance, support high refrigerant throughput, and allow flexible piping layout to suit complex system configurations.
Precision Cast Iron Body | The heavy-duty cast iron cylinder block ensures exceptional mechanical rigidity, vibration damping, and thermal stability, delivering long-term durability under extreme operating pressures and temperatures.
Integrated Motor Protection | The built-in blue control and protection module continuously monitors motor status, providing overload and over-temperature protection to prevent unexpected shutdowns and extend compressor service life.
Anti-Vibration Mounting Base | Reinforced mounting feet with vibration-damping design ensure stable installation, reduce structure-borne noise, and protect connected pipework from mechanical fatigue.

Semi-Hermetic Reciprocating Refrigeration Compressor
Brand: Blait
01 · Product Overview
The Blait YBF6J-16.2DS to YBF6F-30.2DS series are large-capacity semi-hermetic 6-cylinder reciprocating refrigeration compressors, purpose-built for high-load, continuous-duty industrial refrigeration and freezing systems.
Unlike conventional open-type compressors, the semi-hermetic design integrates the motor and compressor within a single precision cast iron housing — permanently eliminating the shaft seal and its associated leakage risk. The result is a compressor that runs cleaner, longer, and with significantly lower maintenance overhead across thousands of operating hours.
02 · Core Features
Semi-Hermetic Sealed Construction |Motor and compressor are fully enclosed within a single cast iron housing. No shaft seal means no leakage path — refrigerant stays in the system, reducing environmental impact and eliminating the most common maintenance failure mode in open-type compressors.
⚙️ 6-Cylinder Heavy-Duty Configuration |The six-cylinder reciprocating mechanism delivers high volumetric efficiency and sustained refrigeration output under continuous heavy-load conditions — ideal for blast freezing, large cold storage, and industrial process cooling where downtime is not an option.
️ Precision Cast Iron Body |Heavy-duty cast iron cylinder block and crankcase deliver superior mechanical rigidity, vibration damping, and thermal stability. Engineered to withstand extreme operating pressures and temperatures — meeting the GB/T 10079-2018 national standard's "extended service life" requirements, with noise and cooling capacity variation both staying within 3dB(A) and 5% throughout the compressor's service life.
Integrated Motor Protection Module |Built-in overload and over-temperature protection continuously monitors motor operating status. Automatic fault response prevents unexpected shutdowns and protects the compressor under abnormal operating conditions.
Large-Bore Flexible Pipe Connections |Oversized suction and discharge ports with large-bore rubber hose fittings minimize flow resistance, maximize refrigerant throughput, and support flexible piping layouts for complex system configurations.
Anti-Vibration Mounting Base |Four reinforced mounting feet with vibration-damping design ensure stable installation, minimize structure-borne noise, and reduce mechanical stress on connected pipework — extending the life of the entire refrigeration system.
