Overview
NELE DL-30100 Cryogenic coolant circulating pump is a mechanical form of refrigeration cryogenic liquid circulation equipment, with the function of providing cryogenic liquid and refrigerating circulator. The product 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 the experimental needs of chemical reactions 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 -30 ℃ to room temperature
3. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
4. Equipped with a microcomputer intelligent Control system, support 0~ 9999 minutes of regular shutdown
5. Large-screen LCD display, Chinese and English, with microcomputer software lock function
6. The domestic circulation adopts a non-heat centrifugal circulation pump to avoid the traditional pump's own heat generation affecting the temperature field of the tank
7. The domestic circulation system is designed with the principle of porous U-shaped reflux circulation to achieve a high uniformity of the flow field and temperature field in the tank
8. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel
9. Humanized R rounded corner design structure to avoid operators being injured by edges and corners
10. The drainage system meets the needs of various laboratories and enterprises for production fluid replacement
11. Multiple Safety protection devices: 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 protection
Principle
The product realizes cryogenic liquid circulation through a fully enclosed Compressor refrigeration system, and integrates a new generation of PID automatic temperature control program with a microcomputer intelligent Control system. The domestic circulation system is based on the principle of non-heat centrifugal circulation pump and porous U-shaped return circulation to ensure uniform distribution of the flow field and temperature field in the tank, so as to achieve accurate temperature control and stable equipment operation.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
Standards
The product information does not mention specific compliance standards
Steps
1. Connect the power supply and turn on the device.
2. Set the required temperature parameters by touching the soft key of the microcomputer
3. Set the scheduled shutdown time (0~ 9999 minutes)
4. Start the domestic circulation system and start cooling
5. Monitor the temperature data of the large-screen LCD display
6. Shut down according to the program after use
Notice
• Make sure the power connection of the device is normal before use
• When setting the temperature, be careful not to exceed the rated range of the equipment (-30 ° C to room temperature)
• Regularly check the water level to avoid triggering the protection function during low water level operation
• Pay attention to the working state of the Compressor to prevent overheating or overcurrent
• Use a water discharge system when changing the liquid to avoid liquid spillage
• Pay attention to the edges and corners of the equipment when operating. Although there is a humanized design, caution is still required
• Immediately check the corresponding protection function and deal with it when an alarm occurs
