Cryocooler Cryogenic Refrigeration System -150℃～-20℃

Microcomputer control, cascade temperature controller, digital temperature display, the regulation of unit 0.1℃, inside the temperature range -20 ℃ ~ -125 ℃ adjustable. Multi-safety protection, more reliable operation. France TECUMSEH compressor, Germany DANFOSS compressor, EMERSON compressor, automatic cascade refrigeration technology. With self-diagnosis function, freezer overload protection, high-pressure switches, overload relays, thermal protection device and other security functions, and fully guarantee the use of safety. Three sealed mold layer of insulation, Extra-thick high-density polyurethane foam insulation layer, the effect of good insulation; Inline vacuum insulation panels. Human design, more convenient and flexible. Suitable for mechanical producing plant use. If the low temperature refrigeration system has been frosted, believing that some enterprises have met, then how should we deal with such situation? Are there any methods can solve this problem. Today, let's know something about it with Guanya refrigeration company. 1. First turn off the suction valve of the low temperature box compressor and unload to the minimum number of cylinders to operate. 2. Then close the liquid supply valve of the intermediate cooler and close the suction valve of the small high pressure cylinder. 3. After the high pressure cylinder is returned to normal, open the suction valve of the large and low pressure cylinder again. When the normal operation has been resumed, then supply the liquid to the intermediate cooler. 4. If the frosting of high pressure cylinder is severe, the operation of the unit must be stopped. 5. Drain the intermediate cooler.
