DHJF-1230 Low-temperature Stirring Reaction Bath

The Characteristics

The company has core technology.

National patent product

1,Leading single-stage compression segregation ultra-low temperature technology can meet

 low temperature need of -120 ℃ to -100 ℃ ..

2,Refrigeration compressors and other key parts adopt the products with famous 

 brands of the United States, Germany, and France and have high reliability, and high efficiency.

3,Digital setting and display of temperature, easy to operate.

4,Circulating system adapts SUS304, 316 and macromole anti corrosion substance, 

 which can resist rust, corrosion, and low temperature liquid pollution.

Advantage

No circulating system under -100 ℃.

The Characteristics of Technical

When the cooling temperature is below -100 ℃, common technology is the use of three cascade 

refrigeration system for cooling, which uses three compressors for cooling. The structure of this 

system is complex and three compressors cause the high cost of investment and running. Besides, 

too many running parts and welding bead bring it many leakage points and make it unreliable and

difficult to maintain. Our company has independently developed the single-stage compression 

refrigeration segregation heat exchanger of entire series combination, and based on which we 

have developed low temperature cooling fluid circulation pump of single compressors which 

can reach temperatures well below -100 ℃ . This model adopts evaporator of coil tube type and 

its coat is equipped with coil pipe structure heat exchanger in series of tandem type . This model

makes heat exchanger in series cascade composed of the evaporation outer tube and the multi-

stage condensation inner tube within the lumen to achieve one compressor form a multi-stage

 refrigeration system and to make the structure of overlay refrigerating system more simple, lower

 production costs, at the same time greatly reduce the craters . Therefore the reliability of the 

refrigeration is improved.
