Overview
NELE DL-20100 Cryogenic coolant circulating pump is a cryogenic liquid circulation equipment that uses mechanical refrigeration, with the function of providing cryogenic liquid and refrigerating circulator. The equipment 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 the experimental needs of chemical reactions and biological reactions in multi-functional low temperature environments.
Features
1. Digital display resolution of 0.01 ° C, large LCD display
2. Temperature Fluctuation of +/- 0.05 ° C
3. Temperature range can be controlled at -20 ℃ to room temperature
4. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
5. Equipped with a new generation of PID automatic temperature control program
6. The domestic circulation adopts a non-heat centrifugal circulation pump to avoid the traditional pump's own heat generation affecting the temperature field of the tank
7. The domestic circulation system is designed for the principle of porous U-shaped reflux circulation to achieve a high degree of uniformity in the flow field and temperature field
8. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel
9. Humanized R rounded corner design structure to avoid operators being injured by edges and corners
10. Safety protection device: power-off protection, upper and lower limit temperature alarm, low water level protection and alarm, temperature loss protection and alarm, heating device low water level anti-dry burning and explosion-proof, Compressor overheating and overcurrent multiple protection
Principle
The equipment adopts mechanical form refrigeration system, and realizes low temperature liquid circulation through fully enclosed Compressor. The domestic circulation system adopts the principle of non-heat centrifugal circulation pump and porous U-shaped return circulation to ensure uniform distribution of flow field and temperature field in the tank. The microcomputer intelligent Control system is equipped with PID automatic temperature control program to achieve accurate temperature regulation and stable operation.
