Product introduction:
With the rapid development of refrigeration equipment market, large fresh cold storage, low temperature cold storage, ice-making equipment, such as more and more, for freon piston compressor has been very difficult to meet the needs of the equipment, the company developed the HLG series of semi-closed medium temperature screw condensing units, respectively satisfied - 5 '~ 5' C, C - 2 (TC ~ - 15 'C's need, can be widely used in large fresh, cold storage, ice, frozen water cooling equipment etc.
This series of products has the following characteristics:
Lai fukang semi-hermetic screw compressor is adopted, it has high efficiency, long life, ð « selections of small, low noise
It has multi-level energy regulation, which can adjust energy according to the change of cold load and reduce energy consumption effectively.
The unit has the compressor coil temperature protection, exhaust temperature protection, low oil level, oil pressure difference and system high and low pressure protection.
