Product description
Parameters
Air-cooled screw chiller:
Air-cooled screw chillers (single/dual series) adopt internationally renowned brands (Hanbell., Bitzer, Germany) screw compressors, high-efficiency finned condensers, dry shell and tube evaporators, and (Danfoss, ALCO, American menson and other internationally renowned brand parts; equipped with German Siemens PLC control system + LCD touch screen display, which makes the unit compact and small in size, low in noise, stable in performance, safe, energy efficient, easy to operate, etc. A number of system safety devices, which can provide chilled water at 4 ° C to 10 ° C, can achieve the requirements of process cooling continuity for 24 hours.
Air-cooled screw chiller features:
1. Air-cooled screw machine cooling capacity range: 102500Kcal/h to 654800Kcal/h optional
2. In addition to the general characteristics of the water-cooled screw unit series, the air-cooled chiller has the greatest advantage of not requiring a water cooling system, as long as it is well ventilated and can be used.
3, air-cooled chillers do not need to be equipped with cooling water pumps, cooling towers and other ancillary equipment, can save a lot of material and engineering installation costs, and even do not need to set up the machine room.
Compressor features:
1. Internationally renowned brand asymmetric toothed high-efficiency compressors, which are 25%-35% higher than ordinary compressors, and US and European patented technologies.
2. the most advanced type of high efficiency 5:6 third generation asymmetric toothed screw
3. semi-closed design, only three moving parts, with fewer parts, low failure rate
4. It can realize three-stage (100%-75%-50%-25%) three-stage (100%-66%-33%) or stepless energy adjustment. The control is flexible and convenient, energy-saving and efficient, easy to maintain.
5. using the world-famous SKF and FAG zero-gap multiple thrust and radial bearings, precision structure, high reliability
6. three-stage oil separation filter, good oil filtering effect, effectively ensure the normal operation of the compressor and the efficient heat exchange of the heat exchanger
7. It adopts pumpless built-in differential pressure oil supply lubrication system, which is energy-saving, efficient and reliable.
8. special fluorine-resistant low iron loss motor design, equipped with reliable motor overheat protection device, effectively ensure the efficient and reliable operation of the motor
9. Equipped with liquid refrigerant injection system under low temperature and heat pump conditions, effectively reducing the working load and exhaust temperature of key components and improving the reliability of compressor operation.
10. Patented exhaust chamber design and continuous rotor gas transmission to ensure low vibration and low noise of the compressor
11. Install an exhaust check valve at the exhaust port to prevent the rotor from reversing during shutdown.
12. a variety of refrigerant selection In addition to R22 refrigerant, you can also choose R134A.R404A.R407C and other environmentally friendly refrigerant.
13. Easy to install and use The unit has completed the welding of the refrigerant pipeline in the factory, the air tightness leak test, the nitrogen filling pressure test, the vacuum test, the fluorine filling full load performance test, and the qualified products meeting the industry standard requirements.
