Structure design
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℃,
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.
