Structure of magnetic centrifugal chiller with VFD:

Features of Water-cooled magnetic centrifugal chiller with VFD:

1) COP up to 6.7 (GB condition)
2) IPLV up to 11.6 (AHRI condition)
3) The operating noise of the unit is less than 74dB(A)
4) Patented high-efficiency falling film evaporator
5) Oil-free design of the system, more efficient and energy-saving
6) Adopt Hanbell two-stage maglev centrifugal compressor
7) High-efficiency liquid-cooled inverter cabinet, small size and high efficiency
8) M-Smart intelligent control system realizes quick start, stop and restart


Advantages of magnetic centrifugal chiller with VFD:

1) High-efficiency
It can save 350,000 yuan in one year of operation and 700,000 yuan in two years. Running for 2 years can save a Mercedes Benz, 2 years payback period.

2) Safe & reliable
Magnetic centrifugal compressor;
Active magnetic levitation bearing &intelligent judgment of surge area;
Timely adjustment of speed and IGV to avoid surge;

3) Environmentally-friendly
Using the world's mainstream environmentally friendly refrigerant R134a, it has good comprehensive performance, and the ozone depletion value (ODP) is 0.

4)Condensation heat energy recovery, free and practical (optional)
Has a patent for heat recovery. Using the patented heat recovery device, the waste heat generated in the refrigeration process is recovered. That is, while providing customers with cold water, a large amount of hot water can also be supplied free of charge.

5)High efficiency heat exchanger with excellent performance
The high-efficiency heat exchanger independently developed and produced is used, and the liquid level is controlled by the electronic expansion valve combined with the liquid level sensor to ensure that the evaporator is always in a high-efficiency heat exchange state.
IPLV reaches 10.7, part load energy efficiency value exceeds 13

6)Magnetic oil-free technology, energy saving and noise reduction
No mechanical friction, noise less than 74dB(A)
Magnetic bearing, reducing energy consumption by 10%
The system is oil-free, reducing the heat exchange loss of the heat exchanger, improving the performance of the heat exchanger, eliminating the complicated oil circuit system and simple maintenance.
