It is mainly supply cryogenic cooling liquid for the user, which can meet the need to maintain working under low temperature conditions of low temperature reaction; With 50 , 100 , 20 , such as the reaction kettle, can be in the reaction kettle materials cooled to - 70 ℃,- 80 ℃.
1) The whole machine adopts microcomputer control, digital display, easy to operate, safe, reliable; temperature display adopts high brightness LED, and also has the high and low voltage protection, hydraulic protection, leakage protection, overload protection, overheating protection function;
2) Environmental protection cfc-free refrigerants suit for international environment refrigerating national standards GB/T7778-2008;
3) The compressor, oil separator, solenoid valve, expansion valve, such as adopt imported famous brand product, to ensure the stability of the refrigeration system;
4) Evaporator is full welded plate heat exchanger, which is small volume, high in thermal efficiency;
5) Low temperature resistant special circulation pump, no leakage, no holding shaft under different temperature conditions.
6) Closed circulating system can avoid refrigerating medium evaporation and pollution, save energy.
7) Bath and circulating system adopts stainless steel SUS304, which can prevent corrosion.
8) The machine is stable and reliable ,which can meet more than 24h of continuous production process of cold source of demand.
9) Air-cooled design can save the water resources.
10)The casing adopts SPCC, antiseptic property better.
