Danfoss Pressure Oil Model MP55
MP 54 and MP 55 differential pressure switch oils are used for safety switches to protect cooling compressors against low pressure.
If the oil pressure is not good, the differential pressure switch will turn off the compressor after a certain time.
MP 54 and MP 55 are used in cooling systems that use non-flammable HCFC and HFC.
Used in MP 55A refrigeration systems with R717.
MP 55A can also be used in systems with HCFC and non-flammable HFC coolers.
The MP 54 has a fixed differential pressure setting.
It also has a fixed thermal relay that is activated by setting the time.
The MP 55 and MP 55A have adjustable differential pressure and are available in both modes with or without a thermal relay.
- Ability to adjust the wide range
- Can be used for defrosting, refrigeration and air conditioning
- Can be used for HCFC and non-flammable HFC refrigerants
- The power connection is made in front of the device.
- Suitable for both alternating and direct currents
- Coil input suitable for cables with a diameter of 6 to 14 mm
- Differential with small cross section.
CE mark according to LVD 2006/95 / EC EN 60947-1, EN 60947 4-1, EN 60947-5-1
Has the definitive certificate of China CCC
The pressure switch operation relies only on the differential pressure.
The pressure difference between the two shock-absorbing cylinders is such that both cylinders operate independently of absolute pressure.
MP 55 and 55A can be adjusted for different pressure differentials by disc (3).
Adjustable differential pressure can be read internally.
The MP 54 has a fixed differential and no pressure regulating disc.
The factory-set differential pressure is stamped on the front panel of the switch
