Overview
The NELE DL-1020 Cryogenic coolant circulating pump is a mechanically refrigerated cryogenic liquid circulation device with the function of providing cryogenic liquids and refrigerating circulators. It can provide circulating cooling for instruments such as Rotary Evaporator, vacuum freeze drying oven, circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, etc., and supports chemical and biological reactions in multi-functional low temperature environments.
Features
1. Digital display resolution is 0.01 ° C, Temperature Fluctuation +/- 0.05 ° C, Temperature range can be controlled at -10 ° C to room temperature
2. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
3. Microcomputer Intelligent Control system, equipped with large-screen highlight LCD screen, Chinese and English display, can be set to shut down regularly for 0~ 9999 minutes
4. The domestic circulation function adopts a non-heat centrifugal circulation pump to avoid the traditional water pump from affecting the temperature field of the tank due to its own heat production
5. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel
6. With power-off protection, upper and lower limit temperature alarm, low water level protection and alarm, temperature runaway protection and alarm, heating device anti-dry burning and explosion-proof, Compressor overheating and overcurrent multiple protection functions
7. Capacity optional 5L to 100L, support non-standard customization, pump maximum Flow rate 13L/min
Principle
The equipment realizes low temperature control through a fully enclosed Compressor refrigeration system, and adopts a microcomputer intelligent PID automatic temperature control program to ensure temperature stability. The domestic circulation system is designed based on the principle of porous U-shaped reflux circulation to achieve a high uniformity of the flow field and temperature field in the tank and avoid heat interference.
Applications
Rotary Evaporator, vacuum drying oven, circulating water vacuum pump, ultraviolet spectrophotometer, Magnetic Stirrer and other instruments of circulating refrigeration, chemical reaction, biological reaction
Steps
1. Connect the power supply and turn on the device.
2. Set the required temperature and control parameters by touching the soft key of the microcomputer
3. Start the domestic circulation pump to ensure normal liquid circulation
4. Monitor the temperature display, and the device automatically runs to the set conditions
5. After use, shut down or manually turn off the device according to the setting timing
6. Drain liquids as needed for cleaning and maintenance
Notice
• Check the water level before use to avoid equipment damage caused by low water level operation
• Ensure stable power supply and prevent power failure from affecting equipment performance
• Regularly clean liners and circulatory systems to maintain hygiene and efficiency
• Pay attention to safety during operation and avoid contact with high temperature or sharp parts
• Follow the equipment alarm prompts and deal with abnormal situations in time
• Non-professionals should not disassemble or modify the internal structure of the equipment
