Overview
NELE DL-10100 Cryogenic coolant circulating pump is a cryogenic liquid circulation equipment using mechanical refrigeration technology, capable of providing cryogenic liquid and refrigerating circulator environment. It is suitable for circulating refrigeration of Rotary Evaporator, vacuum freeze drying oven, circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer and other instruments, supporting multi-functional low temperature chemical and biological reactions.
Features
1. Digital display resolution is 0.01 ° C, Temperature Fluctuation is +/- 0.05, Temperature range can be controlled at -120~ room temperature.
2. Adopt fully enclosed environmentally friendly Compressor refrigeration system, optional imported brands such as Japan's Panasonic or France's Taikang.
3. Microcomputer Intelligent Control system, support 0~ 9999 minutes timing shutdown, large screen LCD display, with microcomputer software lock function.
4. The domestic circulation function adopts a non-heat centrifugal circulation pump to avoid the traditional water pump heat generation affecting the temperature field of the tank body, and to achieve a high degree of uniformity in the flow field and temperature field.
5. The fuselage shell adopts anti-aging electrostatic spraying technology, the liner and countertop are made of S304 brushed stainless steel, and the humanized R rounded corner design avoids operator injury.
6. Safety protection devices include 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.
7. The capacity range can be selected from 5L to 100L, and non-standard customization is supported.
Principle
The product realizes cryogenic liquid circulation through a fully enclosed Compressor refrigeration system, and adopts a microcomputer intelligent Control system and a PID automatic temperature control program to ensure accurate and stable temperature. The domestic circulation system is based on the principle of porous U-shaped return circulation, and uses a heat-free centrifugal circulation pump to avoid its own heat generation affecting the temperature field of the tank, so as to achieve uniform distribution of the flow field and temperature field in the tank.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
Steps
1. Set up the Microcomputer Control system, including temperature parameters and regular shutdown time.
2. Start the device and perform all operations by touching the soft key.
3. Monitor the large-screen LCD display to ensure that the temperature is stable within the set range.
4. Use the drainage system for liquid exchange operation.
Notice
• Avoid operating the heating device at low water levels to prevent dry burning.
• Regularly check the water level to ensure that the low water level protection function is normal.
• Pay attention to Compressor overheating and overcurrent protection to avoid long-term overload operation.
• Pay attention to the edges and corners of the equipment during operation, and use humanized R rounded corner design to reduce the risk of injury.
• Ensure that the drainage system is unblocked to meet the needs of fluid exchange.
