As technical researchers, no matter you work in chemistry, biology, pharmaceutical, environment analysis, food or
academic research,ect, some conventional laboratory instruments you must have used, such as reactor system autoclaves,
pilot systems, mini plant systems,scale up for operational development, double wall reactors, advanced-flow reactors,
distillation systems, material testing, combinational chemistry, semicoductor industry and vacuum chambers,etc.
For all these applications, dynamic temperature control system is very important for you and your efficient research. At the
same time, there's so many kinds temperature control system sales in market, which one is most suitable for you? Or,
which one is more practical for your research?
1. Structure design of TOPTION Dynamic Temperature Control System
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.
Your benefits from TOPTION temperature control system structure design:
1) Only the heat conduction medium in the expansion container touches the oxygen in the air. ( The container
temperature is limited to 60℃ ).
2) No volatilization of the heat conducting medium at high temperature.
3) No need to change the heat conducting medium,
4) Continuous control of the temperature of the below range, can be done without rising the pressure : -80℃ ~ 190℃,
-70℃ ~ 220℃, -80℃ ~ 170℃, -55℃ ~ 250℃, -30℃ ~ 300℃.
2. Display function of TOPTION dynamic temperature control system:
Cooling heating temperature control system display - The refrigeration system's multi-image display displays various
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) Display 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 regrigeration compressor can be set to operate manually or automatically.
11) Simple Menu to use.
Display Clear Curves Simple way to Set Temperature Profiles Show detail information of Alarm Record
3. Process control of TOPTION dynamic temperature control system
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.
4. High repeatability of results control of temperature control system
5. Circulation pump of dynamic temperature control system
High temperature resistant low temperature magnetic drive pump or a leak-free high and low temperature shield-driven pump,
reduce the risk of system leakage. At the same time the system has the advantages of low noise and big traffic flow.
Circulation pump Electronic expansion valve
6. Electronic expansion valve of temperature control system
Wide temperature range of dynamic temperature control system with electronic expansion valve produced by Emersin
company. It can monitor and adjust the number of steps (0~750 Steps / minute) into the motor, precise control the liquid
volume from the refrigerant, Improve control accuracy.
7. Configuration software (Optioanl) of temperature control system
All dynamic temperature control system SUNDI-Series can be connected with the computer. You can install and record
the picture of display on the computer via the configuration software.
Advantages: Communication distance less than 200m, Easily temperature setting, Real time control screen, Curve
Records, Program selection, Alarm screen recording.
8. Security of TOPTION dynamic temperature control system
Many additional features to ensure the safe operation of the system. For the operation to run not normally appear in
the alarm in time and displayed on the touch screen. Phase sequence, leakage protection, refrigeration system high
and low voltage protection, overload the pump, compressor overload, high and low level, two independent over-
temperature protection, water protection, protection of the circulation line shut.
