Display funcation
The Refrigeration system's multi – image displays various information
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.
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 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.
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.
Security
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.
Connecting Pipe
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 temperature control system, channel, and external circulation equipments.
