Reactor TCU Cooling and Heating Equipment

 

Overview of Reactor TCU (Temperature Control Unit) Refrigeration and Heating Equipment Reactor TCU (Temperature Control Unit) is a key device for accurately controlling the temperature in the reactor. It ensures that the temperature in the reactor is always kept within the set range through an efficient refrigeration and heating system, thereby providing ideal environmental conditions for chemical reactions.

The following is detailed information about the reactor TCU refrigeration and heating equipment:

1. System composition

Refrigeration part:

• Compressor: used to drive the refrigerant circulation to achieve cooling effect.

• Condenser: cools high-temperature and high-pressure gas into liquid.

• Evaporator: absorbs heat and reduces the temperature of the medium.

• Expansion valve: adjusts the refrigerant flow and controls the cooling speed.

Heating part:

• Electric heater: directly heats the medium through the principle of resistance heating.

• Oil bath heater: uses heat transfer oil for heating, suitable for high-temperature applications.

• Steam heater: uses steam to exchange heat with the medium, suitable for application scenarios that require rapid heating.

Control system:

• PLC controller: realizes automatic temperature control, and the programmable logic controller is responsible for monitoring and adjusting the temperature.

•Sensor: monitors the temperature changes inside and outside the reactor in real time and feeds back to the control system.

•Display: displays current temperature, set temperature and other parameters for easy monitoring by operators.

Pumping system:

•Centrifugal pump: used to circulate the medium to ensure uniform temperature distribution.

•Inverter: adjusts the speed of the pump to optimize energy consumption.

 

 

2. Working principle

•Refrigeration mode: When the temperature in the reactor is higher than the set value, the TCU starts the refrigeration system. The compressor compresses the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure gas, which becomes a liquid after being cooled by the condenser. Then it is throttled and reduced in pressure through the expansion valve, and enters the evaporator to absorb heat, thereby reducing the temperature in the reactor.

•Heating mode: When the temperature in the reactor is lower than the set value, the TCU starts the heating system. The electric heater, oil bath heater or steam heater heats the medium to the required temperature and circulates the medium through the pumping system to ensure uniform temperature distribution.

3. Features and advantages

•High-precision temperature control: It can achieve a temperature control accuracy of ±0.1℃ or even higher to ensure stable temperature in the reactor.

• Fast response: Advanced control systems can adjust temperature within seconds to adapt to changes in process requirements.

• Large flow circulation: With large flow of medium circulation capacity, ensure uniform temperature distribution.

• Energy saving and environmental protection: Adopt efficient compressor and heat exchanger design to reduce energy consumption and reduce operating costs.

• Multiple safety guarantees: Built-in over-temperature protection, leak detection and other safety mechanisms to ensure safe operation of equipment.

4. Application scenarios

• Drug synthesis: In the production of organic synthetic drugs, TCU is used to control the temperature in the reactor to ensure that the chemical reaction is carried out under optimal conditions and improve the yield and purity of the product.

• Catalyst activation: During the catalyst activation process, TCU can accurately control the temperature to ensure that the activity of the catalyst is maximized and the reaction efficiency is improved.

• Aseptic production: In the production of aseptic preparations such as injections and infusions, TCU provides precise temperature control to ensure a sterile environment and prevent contamination.

• Fine chemicals: TCU can be used for temperature control in fine chemical production to ensure that each step of the reaction is carried out at the optimal temperature and improve the quality and output of the product.

5. Selection considerations

• Temperature range: Select the appropriate temperature range according to the process requirements, usually covering -80°C to +200°C.

• Power requirements: Select the appropriate power according to the volume of the reactor and the required temperature change rate.

• Medium type: Select a suitable heat transfer medium, such as water, ethylene glycol, thermal oil, etc.

• Control system: Select a control system with high-precision control and remote monitoring functions.

• Safety: Ensure that the equipment has the necessary safety protection mechanisms, such as over-temperature protection, leak detection, etc.
