Maneurop Hermetic Reciprocating Compressor | MTZ18-4VM | 3-Phase | R404A/R134a/R407C
Product Description: The MTZ18-4VM is the 3-phase counterpart to the MTZ18 series, optimized for stable and efficient performance in commercial settings. Designed to work with HFC refrigerants such as R404A, R134a, and R407C, it is perfectly suited for the UAE’s demanding high-ambient conditions. The “-4VM” designation indicates a 380-400V 3-Phase (50Hz) power supply, which is the standard for industrial zones and large commercial buildings in Dubai and Abu Dhabi. Like all “Blue” Maneurop compressors, it features a large internal volume and a 100% suction-gas cooled motor, providing exceptional durability and protection against liquid slugging.
Key Features & Benefits:
- 3-Phase Efficiency: Offers higher starting torque and better energy efficiency compared to single-phase models, ideal for continuous-duty commercial applications.
- Extreme Durability: Built with high-quality internal components and a large oil sump to ensure longevity even under heavy thermal loads.
- Rotolock Flexibility: Features Rotolock suction and discharge ports, allowing for easier maintenance and faster swap-outs in the field.
- High Ambient Resilience: Specifically engineered to maintain cooling capacity when outdoor temperatures in the Middle East exceed 45°C.
- Quiet and Smooth: Precision-engineered pistons and balanced internal components minimize vibration, protecting the system’s copper piping from stress cracks.

FAQs:
- Q: Can this 3-phase compressor run on a single-phase supply?
- A: No, this model requires a stable 3-phase 400V power supply. Attempting to run it on single-phase will damage the motor.
- Q: What is the main benefit of using the 4VM (3-phase) over the 5VM (1-phase)?
- A: 3-phase motors (4VM) are generally more reliable for industrial use, have fewer electrical components (no start capacitors required), and offer better electrical balance for the building’s power grid.
- Q: Is it compatible with R134a for a medium-temp chiller?
- A: Yes, the MTZ series is fully compatible with R134a, provided the system is designed for the corresponding pressures and the POE oil is maintained.
