Maneurop Hermetic Reciprocating Compressor | MT28JE4AVE (MT28-4VM) | 3-Phase | R22
Product Description: The MT28JE4AVE (often referred to by its configuration code MT28-4VM) is a core model in the Danfoss Maneurop MT range. It is specifically engineered for use with R22 refrigerant and 160P Mineral Oil, making it the primary choice for maintaining and servicing existing R22 infrastructures in supermarket cold rooms, small chillers, and milk tanks across Dubai and Abu Dhabi.
The “4AVE” designation indicates it operates on a 380-400V 3-Phase (50Hz) power supply, offering the balanced electrical load and high starting torque required for professional installations. Like all Maneurop “Blue” compressors, it features a massive internal free volume and a 100% suction-gas cooled motor, providing critical protection against liquid slugging—a common issue during the intense heat of the Middle Eastern summer.
Key Features & Benefits:
- Industrial 3-Phase Efficiency: Delivers superior energy efficiency and more stable operation for continuous-duty commercial cooling compared to single-phase versions.
- Legendary Liquid Handling: The large internal shell volume acts as a built-in accumulator, protecting valve plates from damage caused by liquid refrigerant return.
- T3 Climate Resilience: Specifically designed to perform under the high-pressure conditions and extreme temperatures typical of the UAE.
- Rotolock Serviceability: Equipped with Rotolock suction and discharge ports to allow for fast, clean, and flexible installation in the field.
- Robust Reciprocating Design: Built with heavy-duty internal bearings and high-precision valves for an extended service life in demanding environments.

FAQs:
- Q: Can I use this MT28JE4AVE (Mineral Oil) with R404A?
- A: No. For R404A or other HFCs, you must use the MTZ28 series which contains POE oil. This MT model is strictly for R22 systems.
- Q: Is this compressor suitable for a walk-in chiller?
- A: Yes, the MT28 is widely used in medium-temperature (MBP) applications like small cold rooms and beverage cooling systems in the UAE.
- Q: Does it include an oil sight glass?
- A: Yes, the MT28JE4AVE features a built-in oil sight glass for easy monitoring of oil levels during routine maintenance.
