Overview
NELE DL-4050 Cryogenic coolant circulating pump is a cryogenic liquid circulation device that uses mechanical refrigeration, with the function of providing cryogenic liquid and refrigerating circulator. It 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 at low temperatures.
Features
1. Digital display resolution up to 0.01 ° C, Temperature Fluctuation +/- 0.05 ° C, Temperature range controllable -120~ room temperature.
2. Adopt fully enclosed environmentally friendly Compressor refrigeration system, optional imported brands such as Japan's Panasonic or France's Taikang.
3. Microcomputer Intelligent Control system, equipped with large screen highlight LCD screen, support Chinese and English display and 0~ 9999 minutes timing shutdown.
4. The capacity range can be selected from 5L to 100L, and non-standard customization is supported.
5. The domestic circulation function adopts a non-heat centrifugal circulation pump to avoid the traditional water pump heat generation affecting the temperature field of the tank body.
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 design structure to avoid operator injuries.
8. The drainage system meets the needs of various laboratories and enterprises for production fluid replacement.
9. Multiple Safety protection devices: power-off protection, upper and lower limit temperature alarm, low water level protection and alarm, temperature runaway protection and alarm, low water level anti-dry burning and explosion-proof heating device, Compressor overheating and overcurrent protection.
Principle
The product is cooled by a fully enclosed Compressor refrigeration system using mechanical form to realize the circulation of cryogenic liquids. The domestic circulation system is designed based on the principle of porous U-shaped return circulation, and uses a heat-free centrifugal circulation pump to ensure the flow field and temperature field in the tank are highly uniform. Microcomputer intelligent Control system integrates PID automatic temperature control program to precisely adjust the temperature.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
