Introduction of low temperature and screw compressor parallel unit:

1.Save investment,to reduce first-time equipment cost;

2.Save power,supply ref.capacity according to need,save 20% power compared to equipping condensing unit with single compressor;

3.Safe processing ,momently monitoring and controlling processing data,with damage warning function to insure processing security;

4.Compact structure,multi compressors concentrate installed,save space and construction period;

5.Full automation,equip with Italian Carel advanced controller for multi-compressor condensing unit;

6.Full protecting function,together with multi-time warning- to -lock function,function of showing failure code,to advanced reliability and maintainability;

7.Multi classes of power adjustment,can adjust power supply by change ref-loading,can efficiently save power cost.

8.Automatic processing balances,rapidly en-long the general service period of the whole unit;

9.Equipped with new type of screw compressor,high efficient,long service life,little noise and little shake.
