Overview
NELE DL-2015 Cryogenic coolant circulating pump is a cryogenic liquid circulation device that uses mechanical refrigeration, with the function of providing cryogenic liquid and refrigerating circulator. The product 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 chemical and biological reactions in multi-functional low temperature environments.
Features
1. Digital display resolution up to 0.01 ° C
2. Temperature Fluctuation +/- 0.05 ℃
3. Temperature range can be controlled -120 ℃ to room temperature
4. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
5. Microcomputer Intelligent Control system, equipped with large screen highlight LCD screen, Chinese and English display
6. The domestic circulation function adopts a non-heat centrifugal circulation pump to avoid the traditional pump's own heat generation affecting the tank body temperature field
7. The domestic circulation system is designed with the principle of porous U-shaped reflux circulation to achieve a high uniformity of the flow field and temperature field in the tank
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. The drainage system meets the needs of various laboratories and enterprises for production fluid replacement
11. Multiple Safety protection devices include power-off protection, upper and lower limit temperature alarm, low water level protection, temperature runaway protection, heating device anti-dry burning and explosion-proof, Compressor overheating and overcurrent protection
Principle
The product 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. Microcomputer intelligent Control system integrates PID automatic temperature control program to precisely adjust temperature.
