Danfoss Oil Differential Pressure Control

Danfoss MP Oil Differential controller

HVAC Danfoss Oil Differential Pressure Control

 

MP54 and MP55 oil differential pressure controls are used as safety switches to protect refrigeration compressors against low lubricating oil pressure.

 

If the oil pressure fails the oil differential pressure controls stops the compressor after a certain time period.

 

MP 54 and 55 are used in refrigerating systems using fluorinated refrigerants.

 

MP 55A is used in refrigerating systems with R717 (NH3), MP 55A can also be used in systems with fluorinated refrigerant.

 

MP 54 has fixed differential pressure setting. It also incorporates a thermal time relay with a fixed release time setting.

 

MP 55 and 55A have adjustable differential pressure and are available both with and without thermal time delay.
