Overview
The NELE DL-1030 Cryogenic coolant circulating pump is a cryogenic liquid circulation device using mechanical refrigeration, capable of providing cryogenic liquid and refrigerating circulator functions. 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 chemical and biological reactions in multi-functional low temperature environments.
Features
Digital display resolution of 0.01 ° C ensures accurate temperature display
2. Temperature Fluctuation is +/- 0.05 ° C, providing stable temperature control
3. Temperature range can be controlled from -120 ° C to room temperature, suitable for a variety of needs
4. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brands such as Japan Panasonic or France Taikang
5. Built-in integrated PID automatic temperature control program, equipped with a large-screen highlight LCD screen, Chinese and English display
6. Capacity optional 5L to 100L, support non-standard customization
7. The domestic circulation adopts a non-heat centrifugal circulation pump to avoid its own heat generation affecting the temperature field, and the porous U-shaped return design realizes a uniform flow field and temperature field
8. The fuselage shell is anti-aging static spray, and the liner and countertop are made of S304 brushed stainless steel
9. Humanized R rounded corner design to avoid operator injuries
10. The drainage system is convenient for laboratory and enterprise fluid exchange
11. 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 environment through fully enclosed Compressor refrigeration system, and adopts mechanical form refrigeration. The domestic circulation system uses the principle of non-heat centrifugal circulation pump and porous U-shaped return to ensure uniform distribution of flow field and temperature field in the tank. The microcomputer intelligent Control system integrates PID automatic temperature control program, and realizes accurate temperature adjustment and timing functions through large-screen LCD display and touch soft key operation.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
Steps
1. Set the temperature and control parameters by touching the soft keys of the microcomputer
2. Start the equipment and perform cryogenic liquid circulation
3. Monitor the temperature and status of the large-screen LCD display
4. After use, change the liquid or shut down through the water discharge system
Notice
• Ensure that the equipment is operating under normal Safety protection function
• Avoid low water level operation to prevent dry burning and damage
• Regularly check the Compressor and circulation system to prevent overheating or overcurrent
• Pay attention to the edges and corners of the fuselage during operation, and use R rounded corner design to reduce the risk of injury
• Use the water discharge system when changing the liquid to ensure the operation specifications
