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.

Display funcation

Displays various information on the touch screen.

Process Control Schematic diagram

High repetative of tempeature control effect

Each cycle curve slope is consistent and greatly improve the consistency of production thermostatically control environment.
