Features of Cooling and Heating Systems

  • It is specially designed and developed for the characteristics of small liquid holding capacity, strong heat exchange capacity, and large pressure drop in the circulation system of the microchannel reactor.
  • Optimize temperature sampling and response speed, specially design control algorithm, can respond quickly to stable temperature control.
  • Enhance the design of the circulating pump capacity to meet the high pressure drop requirements of the reactor.
  • Continuous high temperature cooling technology to meet the requirement of stable operation when the temperature control is required for high temperature exothermic reaction.

Structure Design

A fully closed piping design, high efficiency plate heat exchanger used to reduce the demand for the thermal fluid utilization while providing the system to achieve the rapid ups and downs in temperature.

The whole system is a closed liquid circulation system with the expansion of container, expansion of the container and the liquid circulation is adiabatic, and do not participate in liquid circulation, only mechanical connection, regardless of the temperature is a high temperature or low temperature, the tank temperature is limited to 60℃.

Display Function

  1. Display all the kind of process control temperatures.
  2. Shows the liquid level of the heat conducting medium in the expansion vessel.
  3. Shows indication for refrigeration system working.
  4. Shows indication for heater working.
  5. Shows indication for circulation pump working.
  6. Display the temperature control.
  7. The temperature upper limit, lower limit control can be set.
  8. The temperature difference between jacket & reactor material can be set.
  9. Shows the alarm to add the liquid when it is empty.
  10. The refrigeration compressor can be set to operate manually or automatically.
