Maneurop MLZ Series Scroll Compressors
The MLZ and LLZ series are purpose-engineered for applications in refrigeration with respectively medium and low temperatures.
They suit all operating conditions in different cooling systems.
Optimize your system with the scroll compressors for refrigeration. The combination of an energy efficient motor and an optimized scroll wrap for refrigeration applications delivers high efficiency in fixed-speed compressors. Optional vapor injection boosts the cooling capacity and efficiency by more than 20%.
Improve the sound environment with the lowest sound level in the industry Scroll technology is quiet by design: the scroll provides smooth continuous compression, the absence of suction
and discharge valves, and the unique disc check valve design ensure quiet, vibration-free operations.
Improve your system reliability to reduce your maintenance and warranty costs. Reliability is built into this compressor range, from the compliant scroll design and the engineered bearings to the simplified manufacturing process (30% fewer parts). The patented thermal fault protection also contributes to excellent reliability. A smart way to reduce your field service costs.
Footprint up to 30% smaller than alternative reduces the logistics costs and frees up space in the system.

Boost cooling capacity and efficiency with vapor injection in low temperatures
Danfoss proposes the optional activated economizer line kit to boost compressor efficiency and capacity with vapor injection. The system uses a liquid subcooler circuit. During the liquid subcooler process, some liquid refrigerant evaporates in the economizer and is injected into the scroll set at intermediate pressure. This provides additional cooling capacity thanks to subcooling in the economizer and increases efficiency of the system.
The effect of vapor injection increases together with the increase of the system pressure ratio.
