Features of screw Chillers:

compressor

Adopting German Bizel/Taiwan Fusheng/Hanzhong semi enclosed screw compressors and twin screw series compressors. Twin screw 5:6 teeth ratio and linear design, energy-saving.

Efficient active valve energy control, achieving graded or stepless control. Balanced design, stable and stable operation.

Strict handling of moving parts, design of exhaust oil balance block, long maintenance cycle, and trouble-free operation for over 40000 hours.

Oil separator, with exhaust carrying less than 1.5% of oil.

New evaporator

Internally threaded copper tube, achieving heat transfer effect and good energy conservation.

Using CAD/CAM design and processing technology, the CNC machining center is completed, with a compact structure and compact volume. The U-shaped heat exchange tube bundle can be pulled out as a whole to clean internal scale, facilitating maintenance and repair.

Dry evaporator facilitates oil return, ensuring compressor life and system stability.

Water-cooled condenser

Made of threaded copper pipes, with large heat dissipation and compact size.

Using CAD/CAM design and processing technology, combined with CNC machining center production, the structure is compact and the performance is good. Beautiful appearance and energy-saving.

Microprocessing control system

The centralized control of the PLC unit, combined with the adjustable system of the compressor, can timely and accurately control the matching of the refrigeration capacity and cooling load of the unit, ensuring efficient operation of the unit and reducing operating costs. Internal integration of water interruption, low temperature, high and low pressure, antifreeze, phase loss, and extension

Multiple safety protection and handling functions such as startup, reverse phase, overload, motor overheating, and oil pressure difference. Full Chinese operation interface (can be converted between Chinese and English), menu style prompt, and the operation status of the unit can be set arbitrarily, providing a home appliance operating environment.

Easy to install

1) Balanced and safe operation, low vibration, and easy installation;

2) The unit has a compact structure, small footprint, light weight, and is easy to handle;

3) Complete various performance tests and wiring before leaving the factory to reduce installation time and costs.

Reliable operation

1) The unit adopts multiple refrigeration circuits;

2) Implement interlocking control between the water system and the unit;

3) Compressor unloading and depressurization start, with low starting current;

4) The motor adopts PTC thermal protection.
