Overview
NELE DL-4020 Cryogenic coolant circulating pump is a mechanical form of refrigeration cryogenic liquid circulation equipment, with the function of providing cryogenic liquid and refrigerating circulator. The product 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 the experimental needs of chemical reactions and biological reactions in multi-functional low temperature environments.
Features
1. Digital resolution up to 0.01 ° C, Temperature Fluctuation +/- 0.05 ° C
2. Temperature range can be controlled between -120 ° C and room temperature
3. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
4. Microcomputer Intelligent Control system, equipped with large screen highlight LCD screen, support Chinese and English display
5. 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
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 corner design structure to avoid operators being injured by edges and corners
8. Provide a variety of capacity options: 5L, 10L, 15L, 20L, 30L, 50L, 100L, support non-standard customization
9. Perfect Safety protection device: 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 function of heating device, Compressor overheating and overcurrent multiple protection
Principle
The equipment realizes a low temperature environment through a fully enclosed Compressor refrigeration system, and 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 return circulation, and the flow field and temperature field in the tank are realized by a heat-free centrifugal circulation pump.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
Steps
1. Power on and start the device
2. Set the required temperature parameters by touching the soft key of the microcomputer
3. Set the scheduled shutdown time from 0 to 9999 minutes
4. Start the domestic circulation system to work
5. Monitor the temperature data of the large-screen LCD display
6. Shut down according to the program after use
Notice
Make sure the equipment is in a horizontal and stable position before use
• Regularly check the water level to avoid low water level operation
• Pay attention to the working state of the Compressor to prevent overheating and overcurrent
• Follow safe operating practices when replacing chilled down fluid
• Do not block the ventilating port during the operation of the equipment
• Non-professionals should not disassemble and repair
