If you need a reliable and high-performance machine for cooling water flows, the rotary screw compressor chiller might be just what you’re looking for.
These machines are designed to operate using a compression refrigeration cycle, making them ideal for medium to high refrigeration power ranges. With cooling capacities ranging from 20 tons to 1,000 tons of refrigeration, there is a chiller available to suit your needs.
How do screw compressors work?
- A screw compressor is a machine that increases the pressure of refrigerant gas that has been evaporated in the chiller. This high-pressure refrigerant is then sent to the condenser, where it is turned back into a liquid.
- The screw compressor works by reducing its volume through the rotation of slotted helical screws within a tight tolerance housing.
- The double rotor screw compressor is the most commonly used compressor in larger refrigeration installations, where the rotors rotate in opposite directions to draw gas into the rotors through an inlet port.
- As the screws continue to turn, gas is trapped between the compressor housings and the rotors, and is released through an outlet port at a determined discharge pressure value.
What is the most common refrigerant used in screw chillers?
- The most commonly used refrigerant in screw chillers is R-134A. However, due to environmental restrictions, newer refrigerants such as R513A have also been introduced.
- Some screw chillers also use R410A, although this refrigerant has been replaced by more environmentally friendly options due to its high GWP value.
Which screw chiller is the best seller?
The best-selling chiller is the screw compressor with a water chiller in the range of 100 to 300 KW.
