Overview
NELE DL-3010 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 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 chemical and biological reactions in multi-functional low temperature environments.
Features
1. Digital display resolution of 0.01 ° C
2. Temperature Fluctuation of +/- 0.05 ° C
3. Temperature range can be controlled at -30 ℃ to room temperature
4. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
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 function adopts a non-heat centrifugal circulation pump to avoid the traditional pump's own heat generation affecting the temperature field of the tank
8. The domestic circulation system is designed with the principle of porous U-shaped reflux circulation to achieve a high degree of uniformity in the 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. The drainage system meets the needs of various laboratories and enterprises for production fluid replacement
12. 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 equipment adopts mechanical form refrigeration, and realizes low-temperature liquid circulation through a fully enclosed Compressor refrigeration system. The domestic circulation system is based on the principle of porous U-shaped return circulation, and uses a heat-free centrifugal circulation pump to promote liquid flow to ensure uniform distribution of the flow field and temperature field in the tank. The microcomputer intelligent Control system integrates PID automatic temperature control program to precisely adjust the temperature and keep the equipment running stably.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
Steps
1. Set Microcomputer Control system parameters, including temperature and timed shutdown time
2. Start the equipment and perform cryogenic liquid circulation
3. Monitor the operating status to ensure stable temperature
4. After use, turn off the device according to the procedure
Notice
• Ensure that the equipment operates in a safe environment to avoid abnormal operation
• Regularly check the water level to prevent equipment damage due to low water levels
• Pay attention to Compressor status to avoid overheating or overcurrent
• Use compliant media (e.g. pure water, ethylene glycol, alcohol)
• Follow equipment maintenance procedures to extend service life
