Parallel compressor unit is mostly used to work together with cold rooms, walk in freezers, spiral freezers, tunnel freezers, plate freezers or other refrigeration projects. The compressors quantity on unit can be 2, 3, 4, 5, 6 or more. We use compressors mostly and other compressor brands will be also available according to customers requirement.
Screw Compressor Unit:
High-temperature Type: Evaporating temperature of 12.5°C~-10, and the nominal power of compressor motor is from 60HP to 600HP.
Intermediate-temperature Type: Evaporating temperature of -15°C~-30°C, and the nominal power of compressor motor is from 50HP to 540HP.
Low-temperature Type: Evaporating temperature of -35°C~-45°C, and the nominal power of compressor motor is from 50HP to 540HP.
Standard configuration of screw type parallel compressor refrigeration unit:
1.Low-temp type: screw compressor, liquid receiver, gauge panel,high and low pressure controller, electric cabinet, oil separator, water-cooling type oil cooler, economizer, liquid supply filter,suction line filter,injection components.
2.High-temp type: screw compressor, liquid receiver,gauge panel, high and low pressure controller, electric cabinet, oil separator,spray liquid cooling system, liquid supply filter,suction line filter.
1. Utilized Semi-Hermetic Refrigeration Compressors; Good Quality and Reliable Performance;
2. The products feature by their structures of muti semi-hermetic Compressors paralleled together to from one integrated systems. The discharge pipes, suction pipes are one shared by all the compressors for each units. The paralleled system is simpler for intergrated control and cap adjustment;
3. Structure is compacted to save installation space;
4. According to the change of cooling load,the multilevel energy regulation can be realized and also can reduce the equipment running cost.
5. Reduce the influence on operation that caused by machine failure so as to increase the realibity of the unit operation.
6. R404a, R22 units can be provided.
