Product Description

Excellent performance, high precision, intelligent temperature control, very wide temperature control range, from -120 °C ~ 350 °C, suitable for most enterprises temperature control needs. Product temperature control accuracy of ± 0.5 ° C, cooling power from 0.5 kW to 1200 kW can provide the corresponding products.

Temperature Process Control Principle

Through three-point sampling (material temperature point, temperature control system outlet temperature, temperature control system inlet temperature), and our own model-free self-built tree algorithm and general anti-lag cascade algorithm, solve the problem of large delay in pharmaceutical chemical temperature control.

Advantages of TCU:

  • Users can get a closed and repeatable temperature control in a wide temperature range, which can realize temperature control of - 120 ~ 300 ℃.
  • The built-in electric heating heat transfer oil auxiliary system can automatically start the auxiliary heating system according to the demand to reduce the steam pressure.
  • It can accurately match the heat demand through rapid operation to achieve the purpose of energy conservation.
  • The temperature of the whole reaction process is controlled by fast calculation, and the exothermic and endothermic reactions in the whole reaction process are controlled by fast response.
  • A standardized interface is reserved, and the cold and heat source heat exchange module can be added according to the actual demand.
  • The reaction process temperature and single fluid temperature can be selectively controlled, and the temperature difference between the reaction process temperature and single fluid temperature can be set and controlled.
  • Fully enclosed pipeline design is adopted.
  • To ensure the safe operation of the system, the electric valves can be fully opened manually.
