Air Cooled Two Stage Screw Condensing Unit

Air Cooled Two Stage Screw Condensing Unit

Advantages:

With the rapid development of refrigeration market, there are more and more large-size refrigeration storages, ice making equipment and quick-frozen devices. Freon piston compressor has been difficult to meet the needs of these devices. Our SLLG Series semi-hermetic low temperature condensing unit can meet the refrigeration of -50~-30℃, and can be widely used in large-scale refrigeration equipment.

Details

Features:

◆ The unit equipped with Taiwan Fusheng semi-hermetic two-stage screw compressor, which is with high efficiency, long life, less vibration and less noise;
◆ The unit equipped with complete configuration, which are world well-known refrigeration parts and accessories with high reliability.
◆ The unit has multi-protection for compressor counter rotation, over heat, over load, exhaust temperature, low oil level, oil flow and high-low pressure of the system.
◆ Economizer is integrated which enhance the cooling capacity during low temperature running.
◆ With multi-level energy regulation, energy can be adjusted according to the change of cooling load, which can effectively reduce energy consumption;
