Overview
NELE DL-2050 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, and supports experimental processes such as chemical reactions 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 -20~ room temperature
4. Adopt fully enclosed environmentally friendly Compressor refrigeration system (Japanese Panasonic or French Taikang brand)
5. Microcomputer Intelligent Control system, can be set to shut down regularly for 0~ 9999 minutes
6. Large-screen LCD display with microcomputer software lock function
7. 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
8. Design of porous U-shaped reflux circulation principle to achieve highly uniform flow field and temperature field in the tank
9. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel
10. Humanized R rounded corner design structure to avoid operators being injured by edges and corners
11. 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 realizes a low temperature environment through a fully enclosed Compressor refrigeration system, and integrates a new generation of PID automatic temperature control program with a microcomputer intelligent Control system. Through a heat-free centrifugal circulation pump for domestic circulation, based on the principle of porous U-shaped return circulation, it ensures that the flow field and temperature field in the tank realize turbulence and highly uniform distribution.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
