Low Temperature Cooling Circulator

Description

Description

• 1. TOPTION Brand DL series low-temperature coolant circulation pump is totally enclosed air-cooled refrigeration compressor and microprocessor based control system to provide low-temperature cooling water (liquid) flow or low temperature water (liquid) flow.

  
  

  2. In order to satisfy the cooling water and low-temperature liquid to temperature or constant temperature equipment, 

  
  

  such as evaporation, fermentation, electron microscopy, low temperature chemical reactors, electron spectroscopy, mass spectrometry, densitometer, freeze-drying apparatus, vacuum coating apparatus, the reactor,etc. 

  
  

  3. DL series cooling circulator Can also make a variety of low temperature volume directly in the tank experiment. 

  
  

• 

• 1. Air-cooled completely closed refrigeration compressor, refrigeration system, intelligent control computer automatically open, refrigeration systems with delays, overheating, over-current protection devices such as multiple.

  
  

  2. Circulating pump liquid output can be cold tank, cooling or constant temperature machine outside the experimental container or a second temperature field.

  
  

  3. Microcomputer equipped with timer off function, this feature can be turned from 0 to 100 hours to set the time off any time.

   

  4. Uses the double window, red, green and two color LED display temperature settings and temperature measurement, digital resolution of 0.1 ℃, the temperature measurements may be amended computer error, so the number was 0.1 ℃ accuracy.

   

  5. With computer software lock function, lock the system parameter setting, independent of staff can not change the configuration parameters.

  
  

  6. All of the above operations were based intelligent controller on the completion of pressing the touch pad, easy to operate. 

  
  

  7. Products easy to use, can work.

• 
• 

• 4. Guarantee rapidly cooling under high temperature condition, could come true continuously temperature control between -50℃ ~ 250℃.

  
  

  5. Circulation management use airtight method, no oil mist and water vapor absorption situation, so as to guarantee the safe of your research and the lifetime of conduction liquid.

  
  

  6. Chiller unit use emerson copeland compressor, circulation pump, stable performance and reliable quality.

  
  

  7. Self-diagnosis function, freezer overload protection, high pressure switch, overload relay, thermal protection device, liquid low level protection, high temperature protection and temperature fault protection,etc, security protection function.

  
  

  8. Control heat-conducting medium temperature, whole heating and cooling process use the same kind heat-conducting medium.

  
  

  9. High-lift design, meet the need of heat-conduction medium long distance transmission.

  
  

  10. Adopt R404A environment protection type refrigerant, meet environment protection request.
