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,
no matter 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℃.
The Refrigeration system displays various information on the touch screen.
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 Schematic diagram
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.
High repetative of tempeature control effect
Each cycle curve slope is consistent and greatly improve the consistency of production thermostatically control environment.
Circulation Pump
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.

LNEYA Dynamic Temperature Control systems in practice
In comparison to other thermal control systems, Dynamic Temperature Control systems
differ sometimes considerably in their thermodynamic characteristics. In practice Dynamic Temperature Control systems offer definite advantages in your work: noticeably shorther heating and cooling times, better stability and reproducibility through the entire process
chain, greater safety for expensive glass reactors and the contained substances, together
with simple and easy operation.
Heat Conduction Medium
It is important to choose the suitable heat conduction medium, to make sure that
system works stably.To choose the suitable medium according to the working
temperature of the system is essential.
The package kinds of LNEYA heat conduction medium are 10L, 25L, 30L, 200L.
when ordering the heat conduction medium, the heat conduction medium for constant
temp control system, channel, and external circulation equipments.
