3. Temperature range can be controlled -120~ room temperature
4. The fully enclosed environmentally friendly Compressor refrigeration system adopts imported brands
5. Microcomputer Intelligent Control system supports 0~ 9999 minutes timed shutdown
6. Large-screen LCD display and Chinese-English display
7. domestic circulation without heat centrifugal circulation pump
8. Design of porous U-shaped reflux circulation principle to achieve uniform flow field and temperature field
9. The fuselage shell adopts anti-aging electrostatic spraying technology
10. The liner and countertop are made of S304 brushed stainless steel
11. Humanized R rounded corner design to avoid operator injury
12. Safety protection device
Principle
The equipment realizes the low temperature environment through the fully enclosed Compressor refrigeration system, and adopts the microcomputer intelligent Control system and the integrated PID automatic temperature control program to precisely adjust the temperature. The domestic circulation system ensures the uniform distribution of the flow field and temperature field in the tank through the principle of non-heat centrifugal circulation pump and porous U-shaped return circulation, and avoids the traditional water pump from affecting the temperature field Stability due to its own heat production.
Applications
Rotary Evaporator, Vacuum freeze drying oven, Circulating water vacuum pump, UV spectrophotometer, Magnetic Stirrer, Chemical reaction, Biological reaction
Steps
1. Connect the required refrigeration equipment
2. Choose the right cooling down medium according to the temperature requirements
3. Set the target temperature and working parameters by touching the soft key of the microcomputer
4. Set the scheduled shutdown time (0~ 9999 minutes)
5. Start the equipment to start circulating refrigeration
6. Monitor the temperature data of the large-screen LCD display
7. Shut down according to the program after use
Notice
Temperature range: Choose the right chilling down medium (pure water, ethylene glycol or alcohol)
• Pay attention to the low water level protection function of the equipment to avoid dry burning
• Regularly check the operating status of the Compressor
• Pay attention to safety protection during operation and avoid contact with low temperature surfaces
• Ensure stable power supply to prevent sudden power failure
• Regularly clean and maintain the inner and outer surfaces of the equipment
