Air-cooled screw chillers:
The air-cooled screw chiller (single/double series) adopts internationally renowned brand (Hanbell., Hanbell., Germany) screw compressor, supporting high-efficiency finned condenser, dry shell and tube evaporator and (Danfoss, ALCO, Merson and other international well-known brand parts; Equipped with German Siemens PLC control system + LCD touch screen display, the unit has the advantages of compact structure, small size, low noise, stable performance, safety, energy saving and high efficiency, and easy operation; A number of system safety protection devices can provide 4°C to 10°C chilled water, which can achieve the requirements of continuous 24-hour operation of process cooling.
Concentrate:
1. The refrigeration capacity is measured under the following temperature conditions: the inlet/outlet temperature of chilled water is 12°C/7°C.0°C/-5°C.-5°C/-10°C.
2. Working range: outdoor dry bulb temperature is 33 °C, wet bulb temperature is 28 °C.
3. This series of units can have heat recovery: hot water temperature 35 °C ~ 50 °C
4. The above specifications are subject to change without notice, which helps our company to bring the latest scientific and technological achievements to customers at any time.

Features of air-cooled screw chiller:
1. Air-cooled screw mechanism cooling capacity range: 102500Kcal/h to 654800Kcal/h optional
2. In addition to the general characteristics of the water-cooled screw unit series in terms of assembly performance, the biggest advantage of the air-cooled chiller is that it does not require a water cooling system, as long as it is well ventilated, it can be used conveniently.
3. The air-cooled chiller does not need to be equipped with auxiliary equipment such as cooling water pump and cooling tower, which can save a lot of materials and engineering installation costs, and even does not need to set up a machine room.
Compressor features:
1. International famous brand asymmetric toothed high-efficiency compressor, 25%-35% higher energy efficiency than ordinary compressor, American and European patented technology
2. The most advanced profile line of efficient 5:6 third-generation asymmetrical tooth screw
3. Semi-closed design, only three moving parts, with the characteristics of small number of parts and low failure rate
4. It can realize graded 4-stage (100%-75%-50%-25%), three-stage (100%-66%-33%) or stepless capacity adjustment, flexible and convenient control, energy-saving and easy maintenance.
5. The world-famous SKF and FAG zero-clearance multiple thrust and radial bearings are selected, with precise structure and high reliability
6. Three-stage oil separation filter, good oil filtration effect, effectively ensure the normal operation of the compressor and the efficient heat exchange of the heat exchanger
7. Pump type built-in differential pressure oil supply lubrication system is adopted, which is energy-saving, efficient and reliable
8. Special fluorine-resistant low iron loss motor design, equipped with reliable motor overheating protection device, effectively ensure the efficient and reliable work of the motor
9. Equipped with liquid refrigerant injection system under low temperature and heat pump conditions, which effectively reduces the working load and exhaust temperature of key components and improves the working reliability of the compressor
10. The patented exhaust chamber design and continuous gas transmission of the rotor ensure low vibration and low noise of the compressor
11. Installation of exhaust check valve at the exhaust port can prevent the rotor from reversing when stopping
12. In addition to R22 refrigerant, R134A.R404A.R407C and other environmentally friendly refrigerants can also be selected.
13. Easy to install and use, the unit has completed the welding of refrigerant pipelines, air tightness leak detection test, nitrogen filling pressure holding test, vacuum test, fluorine full load performance test in the factory, and is a qualified product that meets the requirements of industry standards.
