Maneurop Hermetic Reciprocating Compressor | MT28-4VM | 3-Phase | R22
Product Description: The MT28-4VM is a core model in the Danfoss Maneurop MT range, specifically engineered for use with R22 refrigerant and 160P Mineral Oil. In the UAE market—where R22 remains a common standard for existing infrastructures—this compressor is a primary choice for maintaining walk-in chillers, supermarket racks, and small industrial cooling systems. The “-4VM” designation indicates it operates on a 380-400V 3-Phase (50Hz) power supply, providing the high starting torque and balanced electrical efficiency required for professional installations in Dubai and Abu Dhabi.
This compressor features Maneurop’s signature large internal free volume and a 100% suction-gas cooled motor. This specialized design provides a critical safety buffer against liquid slugging and ensures the motor stays cool even when ambient temperatures reach extreme levels during the UAE summer.
Key Features & Benefits:
- Industrial 3-Phase Performance: Offers superior electrical balance and high starting torque, making it ideal for continuous-duty commercial refrigeration.
- Legendary Liquid Handling: The large internal shell volume acts as a built-in accumulator, protecting valve plates from damage caused by liquid refrigerant migration.
- T3 Climate Resilience: Specifically designed to perform under the high-pressure conditions and extreme temperatures typical of the Middle East.
- Rotolock Serviceability: Equipped with Rotolock suction and discharge ports for fast, clean installation and easier maintenance in the field.
- Rugged Industrial Build: Built with heavy-duty internal bearings and high-precision valves for a long service life in demanding environments.

FAQs:
- Q: Can I use this MT28 (Mineral Oil) with R404A?
- A: No. For R404A or other HFCs, you must use the MTZ28 series, which contains POE oil. The MT series is strictly for R22 using mineral oil.
- Q: Is this compressor suitable for a walk-in chiller in Dubai?
- A: Yes, the MT28 is an excellent choice for medium-temperature (MBP) applications like small cold rooms and beverage cooling systems.
- Q: Does it include an oil sight glass?
- A: Yes, the MT28-4VM features a built-in oil sight glass for easy monitoring of oil levels during routine maintenance.
