Overview
The NELE DL-3015 Cryogenic coolant circulating pump is a mechanically refrigerated cryogenic liquid circulation device with the function of providing cryogenic liquid and refrigerating circulator. It 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 display resolution up to 0.01 ° C, Temperature Fluctuation +/- 0.05 ° C, Temperature range can be controlled -30~ 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, operation by touching the soft key.
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 spray technology, the liner and countertop are made of S304 brushed stainless steel, and the 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.
Principle
The product realizes low temperature control 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 heat generation and 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 and time parameters.
2. Start the device and operate it 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 domestic circulation function to keep the temperature of the tank uniform.
5. The regular shutdown function can be automatically turned off within 0 to 9999 minutes.
Notice
• Check the water level before use to avoid low water level operation to prevent dry burning.
• Maintain Compressor and circulatory system regularly to prevent overheating or overcurrent.
• Pay attention to the edges and corners of the equipment when operating, and use R rounded corner design to reduce the risk of injury.
• Ensure that the drainage system is normal and meets the needs of fluid exchange.
• Follow Safety protection function settings such as temperature alarm and power outage protection.
