Mainly used to provide ultra-low temperature circulating cooling liquid for cold equipment and maintain low temperature reactions working under low temperature conditions; it can be combined with 20 L、50L、100L Wait for the use of the reactor to cool the materials in the reactor to -70 ℃、-80℃、-100℃。

● It adopts microcomputer control, fully digital Chinese display, easy to operate. High brightness of temperature display LED。 High and low voltage protection, overload protection, overcurrent protection functions.

● Environmentally friendly, fluorine-free refrigerant, complies with EU and national standards.

● Refrigeration system compressors, oil separators, solenoid valves, expansion valves, etc. all adopt imported brands.

● The evaporator is a fully brazed plate heat exchanger.

● Special circulating pump for low temperature resistance, no leakage or blockage under low temperature operating conditions.

● The circulation system adopts a closed circulation system. No volatile protection for the health of experimental personnel.

● The liquid storage tank and cooling medium are all made of 304 stainless steel, which has good corrosion resistance.

● The whole machine is stable and reliable, and can meet 24 h The above requirements for process cold sources for continuous production.

● The cooling mode of the host is air-cooled.

● The shell is electrostatically sprayed SPCC， Good anti-corrosion effect.
