Dynamic Temperature Control System

SUNDI Serise

Typical Applications

1.Dynamic Constant Temperature Control Of High Pressure Reactor Cold And Heat Source/Double-Layer Glass Reactor/Double-Layer Reactor Cold And Heat Source;
2.Constant Temperature Of Microchannel Reactor Control;
3.Steaming System Temperature Control;
4.Material Low Temperature High Temperature Aging Test;
5.Semiconductor Equipment Cooling Heating;
6.Vacuum Chamber Cooling Heating Constant Temperature Control.


The method of changing the control setting value can respond to the system lag in the process as soon as possible and get a small system overshoot.

Through three-point sampling (material temperature point, outlet temperature of temperature control system, inlet temperature of temperature control system), through the combination of our company’s self created model free recommendation algorithm and general anti lag cascade algorithm.

    SUNDI adopts fully enclosed pipeline design, high-efficiency plate heat exchanger.   Reduces the need for thermal fluid utilization while providing the system with a   rapid rise and fall in temperature.

    The heat transfer medium is in a closed liquid circulation system with an expansion   vessel, and the liquid cycle is adiabatic and does not participate in the cycle, only   mechanical connection. No matter the temperature is high or low, the temperature   of the expansion tank is kept at room temperature to 60 °C, which effectively reduces   the risk of moisture absorption and volatilization of the heat transfer medium during   operation.

    SUNDI Series Dynamic Temperature Control System Can Be Either Air-Cooled Chiller   Or Water-Cooled Chiller. The Choice Of Air Cooling Or Water Cooling Depends On   Your On-Site Process Conditions And Requirements, You Can Explain To Us At The   First Time, So As To Better Choose The SUNDI Model.

Application Field

Customer Case

From laboratory benchmarks to large factories

    In chemical and biological processes, the transformation of substances usually takes place in reactors, which can create consistent conditions and a safe space for the reactions. Dynamic compensation of exothermic or endothermic chemical reactions presents a greater challenge to temperature control systems. Especially if the reaction takes place in extreme temperature ranges, the temperature control system must provide fast compensation.

    Therefore, a temperature control system is used that reacts highly dynamically to temperature changes inside the reactor, compensates quickly and reliably, and automatically adjusts back to the optimal range. This not only ensures efficient, consistent results, but also the safety of the process.

Advantages of SUNDI system

● Working temperatures from -120°C to +350°C
● Previously unachievable performance
●Intelligent temperature control
● Maximum process stability and reproducibility
● Adop plate heat exchager, Pipeline heating, the fastest
heating and cooling rates.
● High cooling power from 0.5 to 1200kW
● Large temperature range without fluid change
● Closed system, extend thermal fluid lifetime
● Incredibly compact
● 7-inch, 10-inch color TFT touch screen display
● Comprehensive warning and safety functions
● Rapid cooling down from high temperature (from 300 °C)
● Use magnetic drive pump, solve the circulation pump leakage

The temperature of each curve is controlled, the inlet temperature of the heat transfer oil and the temperature of the material can be independent (set the temperature difference), and the temperature difference can be controlled.

    ● Only the heat conduction medium in the expansion container touches the oxygen in the air. (Container temperature is limited to 60°C).
    ● 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: -90°C~195°C, -70°C~220°C,-55°C~250°C, -25°C~300°C.
