Overview
The NELE DL-4005 Cryogenic coolant circulating pump is a cryogenic liquid circulation device that uses mechanical refrigeration to provide cryogenic liquids and refrigerating circulators. 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 and other applications.
Features
1. Digital display resolution is 0.01 ° C, large screen LCD display, Temperature Fluctuation is +/- 0.05 ° C.
Temperature range can be controlled at -120 ° C to room temperature, optional -50 ° C to room temperature, medium according to Temperature range selection of pure water, ethylene glycol or alcohol.
3. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brands such as Japan's Panasonic or France's Taikang.
4. Microcomputer Intelligent Control system, can be set to shut down regularly for 0~ 9999 minutes, with microcomputer software lock function, all operations are carried out by microcomputer touch soft keys.
5. 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 generation, and to achieve a high degree of uniformity in the flow field and temperature field in the tank body.
6. The fuselage shell adopts anti-aging electrostatic spraying technology, and the liner and countertop are made of S304 brushed stainless steel. The humanized R rounded corner structure is designed to avoid operator injury.
7. Safety protection devices include 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 heating device, Compressor overheating and overcurrent multiple protection.
Principle
The product uses a fully enclosed and environmentally friendly Compressor for refrigeration through a mechanical form refrigeration system to provide low temperature liquid circulation. The domestic circulation system adopts the principle of porous U-shaped return circulation, combined with a heat-free centrifugal circulation pump, to ensure the flow field and temperature field in the tank are highly uniform. Microcomputer Intelligent Control system integrates PID automatic temperature control program to achieve accurate temperature regulation and stable operation.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
Notice
1. Make sure the equipment is in a safe condition before use, and avoid running the heating device at a low water level to prevent dry burning and explosion.
2. Regularly check the water level to prevent low water levels from alarming or damaging the equipment.
3. Pay attention to the temperature setting of the equipment during operation to avoid triggering an alarm beyond the upper and lower limits.
4. Ensure that the Compressor is not overheated or overcurrent, and stop the machine in time if there is any abnormality.
5. The equipment shell and liner are made of stainless steel and anti-aging spray to avoid scratches from hard objects.
6. The drainage system can be used for laboratory fluid exchange, and safety procedures are followed during operation.
