They are robust and highly durable equipment, used on a large scale in industrial refrigeration systems. Its maintenance is more centralized and simple.
Compressors are normally Scroll and Screw. Since, those with Scroll compressors are found in equipment ranging from 12 Tons of refrigeration to 150 Tons of refrigeration on average.
And those with Screw compressors are found in equipment ranging from 100TR to 350 Ton of refrigeration on average. The main difference between the scroll compressor and the screw compressor is in its robustness and the cost of the equipment.
Screw compressors are more robust, have fewer moving parts, which results in greater system reliability. They are widely used in industrial applications. On the other hand, they have a higher initial investment cost.
