TCU System
This is an introduction to the TCU (Temperature Control Unit) system of Wintech Co., Ltd.
What is a TCU?
A TCU is a device that precisely controls the temperature of target equipment
by circulating a heat transfer medium (water or oil). Unlike simple heating and cooling systems with large temperature control deviations,
ts key feature is the simultaneous control of heating
and cooling to accurately maintain the set-point temperature.
Main Components
Heat Transfer Circulation Pump: Equipment that circulates the heat transfer medium between the equipment and the TCU system.
Heating Source (Heater): Heats the heat transfer medium via an electric heater or a steam heat exchanger.
Cooling Source (Chiller/Cooler): Removes heat from the heat transfer medium using cooling water and a chiller.
Control Panel (PLC): A system that minimizes deviation by applying PID control logic.
Main Tank/Vessel: A vessel that stores the heat transfer medium where heating and cooling are performed.
Temperature Sensor: A sensor that measures the temperature of the heat transfer medium, reactor inlet/outlet, and process materials.
Expected Benefits
Enables Precise Temperature Control
It enables precise control at ±0.1°C without reaction runaway or cooling delays, making it essential for processes sensitive to minor temperature fluctuations such as polymer synthesis and pharmaceutical production.
Broad Operating Temperature Range
A single system is capable of continuous temperature control from -50°C low-temperature cooling to above 200°C high-temperature
heating.
Longer Equipment Lifespan
By gradually adjusting the temperature of the heat transfer medium before supplying it to the reactor jacket, rather than directly introducing steam or cooling water, thermal shock to the equipment is minimized.
