Overview
The NELE DL-1005 Cryogenic coolant circulating pump is a mechanically refrigerated cryogenic liquid circulation device with the function of providing cryogenic liquid and refrigerating circulator. The product is suitable 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 up to 0.01 ° C, Temperature Fluctuation of +/- 0.05 ° C, Temperature range -10~ 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 supports 0~ 9999 minutes of regular shutdown, equipped with large-screen LCD display and microcomputer software lock function.
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 body due to its own heat production, 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, and the liner and countertop are made of S304 brushed stainless steel, with humanized R rounded corner design.
6. Provide a variety of Safety protection devices, including power-off protection, upper and lower limit temperature alarm, low water level protection, temperature loss protection, heating device anti-dry burning and explosion-proof, Compressor overheating and overcurrent multiple protection.
7. Capacity optional 5L, 10L, 15L, 20L, 30L, 50L, 100L, support non-standard customization.
Principle
The product uses a fully enclosed Compressor refrigeration system, adopts mechanical refrigeration, and combines microcomputer intelligent control technology to achieve precise control of cryogenic liquid circulation and temperature. The domestic circulation system is based on the principle of porous U-shaped return circulation to ensure 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 equipment and perform cryogenic liquid circulation operations.
3. Monitor the operating status to ensure that the Safety protection function is normal.
Notice
• Check the water level before use to avoid low water level operation.
• Maintain Compressor and circulatory system regularly to prevent overheating or overcurrent.
• Pay attention to the edges and corners of the equipment during operation to avoid accidental injuries.
• Use a water discharge system when changing the liquid to ensure safe operation.
