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℃. Therefore,
during the process the risk of imbibing and volatilization of the heat conducting medium is reduced.
There following advantages for the user.
Only the heat conduction medium in the expansion container touches the oxygen in the air.
(The container temperature is limited to 60℃).
No volatilization of the heat conducting medium at high temperature.
No need to change the heat conducting medium. Continuous control of the temperature of the below
range can be done without rising the pressure: -80℃~190℃, -70℃~220℃, -88℃~170℃, -55℃~250℃,
-30℃~300℃.
Display function:
1. Displays 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. Displays the temperature control
(materials temperature control pattern, heat conducting medium 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.
11. Simple Menu to use.
Process Control Principle
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 feedforward
with PV, the master PID loop operation results of the PV output and feedforward 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.
