Overview
The NELE DL-3030 Cryogenic coolant circulating pump is a mechanically refrigerated cryogenic liquid circulation device with the function of providing cryogenic liquids and refrigerating circulators. It can provide circulating refrigeration for instruments such as Rotary Evaporator, vacuum freeze drying oven, circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, etc., and supports multi-functional chemical and biological reactions at low temperatures.
Features
1. Digital display resolution of 0.01 ° C
2. Temperature Fluctuation of +/- 0.05 ° C
3. Temperature range can be controlled at -30~ room temperature
4. Adopt fully enclosed environmentally friendly Compressor refrigeration system, imported brand (Japan Panasonic or France Taikang)
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 due to its own heat production
6. The fuselage shell adopts anti-aging electrostatic spray technology, and the liner and countertop are made of S304 brushed stainless steel
7. With a humanized R-rounded design structure, operators can avoid being injured by edges and corners
8. Safety protection device, including power-off protection, temperature alarm, low water level protection, temperature control protection, anti-dry burning and explosion-proof function and Compressor multiple protection
Principle
The equipment realizes low temperature control through a fully enclosed Compressor refrigeration system, adopts an integrated PID automatic temperature control program, and is equipped with a large-screen LCD screen to ensure accurate and stable temperature. The domestic circulation system is designed based on the principle of porous U-shaped reflux circulation to achieve high uniformity 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 the microcomputer intelligent Control system, can be set to shut down at 0~ 9999 minutes
2. All operations are performed by touching the soft keys of the microcomputer
3. Select pure water, ethylene glycol or alcohol as medium according to Temperature range
4. Start the domestic circulation system to ensure uniform flow field and temperature field
5. Use the drainage system for liquid change operation
Notice
• Safety protection equipment to ensure normal operation
• Avoid low water level operation to prevent dry burning and damage
• Regularly check Compressor status to prevent overheating or overcurrent
• Pay attention to avoid being injured by the edges and corners of the equipment during operation, and use R rounded corner design
• Use a special drainage system when changing the liquid to ensure safe operation
