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 a expansion of container, expansion of the container and the liquid circulation is adiabatic, it will not in liquid circulation, only mechanical connection, regardless of the temperature is a high temperature or low temperature, the tank temperature is limited to 60°C. The advantages by this design:

  1. Only the heat conduction medium in the expansion container touches the oxygen in the air. (The container temperature is limited to 60°C), therefore, during the process the risk of imbibing and volatilization of the heat conducting medium is reduced.
  2. No volatilization of the heat conducting medium at high temperature.
  3. No need to change the heat conducting medium. Continuous control the temperature range to -80°C~190°C, -70°C~220°C, -88°C~170°C, -55°C~250°C, -30°C~300°C without rising the pressure.

Display function

  1. All the kind of process control temperatures.
  2. Liquid level of the heat conducting medium in the expansion vessel.
  3. Indication working status of refrigeration system.
  4. Indication working status of heater.
  5. Indication working status of circulation pump.
  6. Temperature control mode (materials and heat transfer medium).
  7. Temperature upper limit and lower limit can be set.
  8. Temperature difference between jacket & reactor material can be set.
  9. Alarm when liquid is empty.
  10. Refrigeration compressor can be set to operate manually or automatically.
  11. Clear temperature curve displayed, it can be zoom and exported to computer.
  12. Recipe procedure set display
  13. Alarm note display

Principle of process control
Change the control settings of the method, the response as soon as possible in the process of the system lags behind, be the smallest system overshoot. Controlled by two PID (PID is a variable in each group) control loop structure, known as the two sets of control loops: the main circuit and from the circuit, the main control loop from the loop output as the settings. System with feed forward with PV, the master PID loop operation results of the PV output and feed forward signals as the composite of the settings from the control loop, through such control of the temperature gradient to ensure the accuracy of temperature control system.

Safety protection
Phase sequence, leakage protection, high and low pressure cooling system protection, pump overload, compressor overload, high and low level, two separate over-temperature protection, water protection, circulation line shut protection.
Note: air-cooled model and temperature below -45°C fitted up with a water-cooled auxiliary heat exchanger to ensure superior cooling effect in high environment temperature.
