Overview
The LT-20-80 ultra-low temperature circulating chill down device is a device produced by GREATWALL, which is mainly used to provide ultra-low temperature circulating chill down liquid for cooling equipment to meet the requirements of low temperature reaction conditions. The device can be used with 20L, 50L, 100L and other Reaction Kettles to chill down the materials in the Reaction Kettle to -70 ℃, -80 ℃, -100 ℃.
Features
1. Using microcomputer control, full digitalization Chinese display, easy to operate, temperature using high luminance LED display.
2. With high and low voltage protection, overload protection, overcurrent protection, ground fault protection and other protection functions.
3. Environmentally friendly refrigerant without fluorine, in line with European Union and national standards.
4. Refrigeration system Compressor, oil separator, solenoid valve, expansion valve, etc. are imported brands.
5. The evaporator is a fully brazed plate heat exchanger.
6. Special circulating pump for low temperature resistance, no leakage and no blocking under low temperature conditions.
7. The circulatory system is closed and non-volatile, protecting the health of the experimenter.
8. The liquid storage tank and circulation pipeline are made of 304 stainless steel, which has good corrosion resistance.
9. The whole machine is stable and reliable, capable of continuous operation for a long time.
10. The host Cooling mode adopts Air-Cooled.
11. The shell adopts electrostatic spraying SPCC, which has good anti-corrosion effect.
Principle
The equipment generates cooling capacity through its refrigeration system (using imported Compressors and other components and environmentally friendly refrigerants), and transfers the cooling capacity to the refrigerant in the closed circulation system through heat exchange by a fully brazed plate evaporator. The cryogenic special circulating pump drives the chilled down liquid to circulate between the equipment reservoir and external cooling equipment (such as Reaction Kettle), thus providing continuous low temperature chilling down conditions for external equipment. The microcomputer Control system ensures accurate and stable temperature.
Applications
It is necessary to provide various types of Reaction Kettles and low temperature chemical reactions for ultra-low temperature circulating chilled down liquids
