Product details
Maneurop Hermetic Reciprocating Compressor | MT22-4VM | 3-Phase | R22
Product Description:
The MT22-4VM is a core model in the Danfoss Maneurop MT series, specifically engineered for use with R22 refrigerant and 160P Mineral Oil. In the UAE’s maintenance and retrofit market, this compressor is a top choice for keeping existing R22 systems running efficiently. The “-4VM” designation indicates a 380-400V 3-Phase (50Hz) power supply, which offers the high starting torque and balanced electrical performance required for industrial and commercial environments in Dubai and Abu Dhabi.
Like all Maneurop reciprocating models, it features a massive internal free volume and a 100% suction-gas cooled motor. This specialized design provides a critical safety buffer against liquid slugging and motor overheating—common challenges during the intense heat of the Middle Eastern summer.
Key Features & Benefits:
- Industrial 3-Phase Performance: Provides superior starting torque and electrical efficiency for continuous-duty commercial applications compared to single-phase units.
- Legendary Liquid Handling: The large internal shell acts as a built-in accumulator, protecting the internal valve plates from damage caused by liquid refrigerant return.
- High Ambient Resilience: Specifically engineered to perform under the high-pressure conditions typical of the Middle Eastern climate.
- Rotolock Serviceability: Equipped with Rotolock suction and discharge ports for fast, clean installation and easy field maintenance.
- Robust Reciprocating Tech: Features high-precision internal components designed to withstand years of heavy cycling in commercial kitchens and cold stores.

FAQs:
- Q: Can I use R404A with this MT22-4VM compressor?
- A: No. This model is charged with Mineral Oil for R22. For R404A applications, you must use the MTZ22-4VM which is charged with POE oil.
- Q: Is a start capacitor required for this model?
- A: No, 3-phase compressors (4VM) do not require start or run capacitors, making the electrical setup simpler and more robust than single-phase versions.
- Q: Where is this compressor typically used in the UAE?
- A: It is widely used in medium-temperature walk-in chillers, beverage coolers, and small industrial process chillers in Sharjah and the Northern Emirates.
