High performance and reliability refrigeration Chillers with heat exchangers in medical industry to cool equipment


Chillers are machines that utilize a refrigeration cycle to remove heat from various liquids and release it into the atmosphere. The next step in the chilling process involves directing the chilled liquid, or coolant, to a heat exchanger to cool air, process equipment, or another liquid. Chillers come in a wide range of designs and sizes. For smaller applications, chillers may be manufactured as localized, small, or portable units. Alternatively, large chillers can be designed to keep entire facilities cool.


Feature


1. Air-cooled screw chillers Compressors using international brands(Bizter,Hanbell), new high-performance screw-rotor compressor, compressor performance than the average 20% -30%.

3. Capacity control can be four-stage (100% -75% -50% -25%) or three-stage (100-66% -33%) and stepless control system.

4. Air-cooled screw chiller with 11 bearings and axial thrust balance a-a combination of design, a substantial increase in bearing life 2.5-3.5 times.

5. The use of high-efficiency silicon steel sheet special groove design, and is equipped with internal and external omnidirectional design cooling flow to the compressor motor in any load can play a high efficiency.

6. Unique built-in hydraulic system, no need to ensure that the oil pump compressor lubrication to maintain oil separation using double-layer filter, oil filter effect is good, the heat exchanger can play.

7. High efficiency, low noise, low vibration.

8. A variety of refrigerants to choose from, in addition to R22 refrigerant, you can also use R134a, R407c and other environmentally friendly refrigerant.
