1. Energy-saving 

◆ Bitzer Hanbell Compressor Water Screw Chiller meets the national energy-saving standards, reduce energy consumption, reduce user operating costs.

◆ Bitzer Hanbell Compressor Water Screw Chiller meets the needs of different users.


2. Compact structure, easy installation and maintenance

◆ Compact structure design, small occupation area.

The evaporator and condenser are arranged in parallel to reduce the center of gravity of the unit and ensure transportation safety.

The whole machine has been filled with sufficient refrigerant and frozen oil before leaving the factory, without on-site perfusion.

◆ The whole machine has been tested in accordance with the national standard and user specified conditions before leaving the factory. Only water pipe and power supply can be connected to the site.


3. Double machine parallel system, higher comprehensive energy efficiency ratio

◆ When the chiller is running all the year round, more than 90% of the time is running at partial load. The double compressor system shares a refrigerant loop, which is more efficient in partial load operation.

◆ Compressor suction and exhaust isolation valves are set for the multi-head units. When one compressor needs maintenance, it will not affect the operation of other compressors.


4. High efficiency oil return system

◆ Patented high efficiency oil separator, injection return oil and multi-system oil balance technology, can reliably return oil under harsh conditions.

◆ Specially designed for full liquid chiller system, set low oil level protection control, completely eliminate the possibility of less oil damage compressor.

Installation is simple

1) Safe operation balance, small vibration, simple installation;

2) Bitzer Hanbell Compressor Water Screw Chiller has the advantages of compact structure, small footprint, light weight and easy handling;

3) Complete various performance tests before delivery, complete wiring, reduce installation time and cost.


Reliable operation

1) Bitzer Hanbell Compressor Water Screw Chiller adopts multiple refrigeration loops;

2) Realize interlocking control of water system and unit;

3) Compressor unloading step-down start, starting current is small;

4) The motor adopts the world's advanced Japanese PTC thermal protection, more sensitive and reliable protection.
