Overview
The NELE DL-2020 Cryogenic coolant circulating pump is a mechanically refrigerated cryogenic liquid circulation device with the function of providing cryogenic liquid and refrigerating circulator. The device provides circulating cooling for instruments such as Rotary Evaporator, vacuum freeze drying oven, circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, etc., and supports 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 can be controlled -120~ room temperature
2. Adopt fully enclosed environmentally friendly Compressor refrigeration system, optional imported brands (Japan Panasonic or France Taikang)
3. Microcomputer Intelligent Control system, equipped with large screen highlight LCD screen, support 0~ 9999 minutes timing shutdown
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. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel
6. Humanized R rounded corner design structure to avoid operators being injured by edges and corners
7. Provide a variety of Safety protection devices: power-off protection, temperature alarm, low water level protection, temperature runaway protection, anti-dry burning and explosion-proof function, Compressor overheating and overcurrent multiple protection
Principle
The equipment realizes low temperature control through a fully enclosed Compressor refrigeration system, adopts a microcomputer intelligent Control system and an integrated PID automatic temperature control program to ensure accurate and stable temperature. The domestic circulation system is designed based on the principle of porous U-shaped reflux circulation, and realizes the flow field and temperature field in the tank.
