Overview
NELE DL-1505 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 resolution up to 0.01 ° C, Temperature Fluctuation +/- 0.05 ° C
2. Temperature range can be controlled at -15 ℃ to room temperature
3. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
4. Equipped with a large-screen high-brightness LCD screen, with Chinese and English display
5. The domestic circulation system 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 liner and countertop are made of S304 brushed stainless steel, and the shell is made of anti-aging static spray technology
7. With power-off protection, upper and lower limit temperature alarm, low water level protection, temperature runaway protection, heating device anti-dry burning and explosion-proof, Compressor overheating and overcurrent multiple protection functions
8. Capacity optional 5L, 10L, 15L, 20L, 30L, 50L, 100L, support non-standard customization
Principle
The product adopts mechanical form refrigeration, and realizes low temperature liquid circulation through fully enclosed Compressor refrigeration system. The domestic circulation system adopts the principle of non-heat centrifugal circulation pump and porous U-shaped return circulation to ensure the flow field and temperature field in the tank are highly uniform. The microcomputer intelligent Control system is equipped with PID automatic temperature control program to achieve accurate temperature control.
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. Set the scheduled shutdown time from 0 to 9999 minutes
2. All operations are performed by touching the soft keys of the microcomputer
3. Select the appropriate medium (pure water, ethylene glycol, alcohol) according to the Temperature range
4. Start the equipment for circulating refrigeration
Notice
• Please confirm that the device is in normal working condition before use
• Select the appropriate circulating medium according to the Temperature range
• Pay attention to the water level of the equipment and avoid low water level operation
• Regularly check whether the Safety protection function of the equipment is normal
