Overview
The NELE DL-3020 Cryogenic coolant circulating pump is a mechanically refrigerated cryogenic liquid circulation device with the function of providing cryogenic liquid and refrigerating circulator. The device can be used for circulating refrigeration of Rotary Evaporator, vacuum freeze drying oven, circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer and other instruments, supporting multi-functional chemical and biological reactions under low temperature conditions.
Features
1. Digital display resolution up to 0.01 ° C, Temperature Fluctuation +/- 0.05 ° C, Temperature range -30~ room temperature
2. Fully enclosed environmentally friendly Compressor refrigeration system, using imported brands (Japan Panasonic or France Taikang)
3. Microcomputer Intelligent Control system, equipped with large screen highlight LCD screen, support Chinese and English display
4. The domestic circulation function adopts a non-heat centrifugal circulation pump to avoid the traditional pump's own heat generation affecting the temperature field of the tank
5. Design of porous U-shaped reflux circulation principle to achieve highly uniform flow field and temperature field in the tank
6. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel
7. Humanized R rounded corner design structure to avoid operators being injured by edges and corners
8. Safety protection devices, including power-off protection, temperature alarm, low water level protection, etc
9. Capacity optional 5L to 100L, support non-standard customized production
Principle
The equipment realizes cryogenic liquid circulation through a fully enclosed Compressor refrigeration system, and integrates a new generation of PID automatic temperature control program with microcomputer intelligent control technology. The domestic circulation system is based on the principle of porous U-shaped reflux circulation, and uses a heat-free centrifugal circulation pump to drive liquid flow to ensure uniform distribution of temperature field and flow field in the tank, so as to achieve accurate temperature control and stable low temperature environment.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
