What is the role of the reactor refrigeration and heating circulator? How to choose?

The refrigeration and heating circulator is a device that can provide precise temperature control for the reactor. It can realize heating and cooling functions at the same time. It is suitable for chemical reaction processes that require precise temperature control over a wide temperature range.

The following are the basic principles and steps of the refrigeration and heating circulator for reactor temperature control:

Heating process:

• Heating medium: High and low temperature all-in-one machines usually use thermal oil or other heating media as heat transfer media.
• Heating cycle: The heating medium is first heated to the required temperature and then transported to the jacket or built-in heating coil of the reactor through a circulation pump.
• Temperature control: The temperature of the heating medium is precisely controlled by a PID controller or other advanced temperature control system to control the temperature in the reactor.
• Heat exchange: The heating medium exchanges heat with the reaction materials inside the reactor, so that the temperature in the reactor gradually increases to the set value.

Cooling process:

• Cooling medium: When the temperature in the reactor needs to be lowered, the high and low temperature all-in-one machine will use a cooling medium (usually water or a mixture of water and antifreeze).
  •Cooling cycle: The cooling medium is delivered to the jacket or built-in cooling coil of the reactor by a circulating pump.
  •Temperature control: The temperature of the cooling medium is precisely controlled by a PID controller or other temperature control system to control the temperature inside the reactor.
  •Heat exchange: The cooling medium exchanges heat with the reaction materials inside the reactor, so that the temperature inside the reactor gradually decreases to the set value.

The following are key factors to consider when selecting a reactor refrigeration and heating circulator:

1. Reactor capacity:

• Larger reactors generally require more powerful heating and cooling systems to ensure rapid and uniform temperature changes.
• Smaller reactors may require a less powerful system, but still need to ensure the accuracy and stability of temperature control.

2. Temperature control range:

• Determine the minimum and maximum temperatures required for the process to select a high and low temperature all-in-one machine that can cover this temperature range.
• For some special processes, extreme temperature changes may be required, and it is necessary to select equipment that can provide a wide temperature range.

3. Heating and cooling rate:

• According to the process requirements, select equipment that can provide the required heating and cooling rates to ensure fast response and efficient production.
• Fast heating and cooling rates help improve production efficiency, especially in processes that require frequent changes in temperature conditions.

4. Temperature control accuracy:

• Select equipment with high-precision temperature control capabilities to ensure process stability and product quality.
• Temperature control accuracy is usually between ±0.5°C and ±1°C. For processes that require higher accuracy, more precise control capabilities may be required.

Advantages of LNEYA’s reactor refrigeration and heating circulator:

1. Safety protection:

• Overtemperature protection: When the temperature in the reactor exceeds the set safety threshold, the equipment will automatically stop heating and start the cooling system to prevent overheating.
• Pressure protection: The equipment is equipped with a pressure protection device to prevent safety problems caused by excessive internal pressure in the system.
• Leak detection: The leak detection device ensures that the heating or cooling medium will not leak, ensuring the safe operation of the equipment.

2. Automation and remote control:
   •Programming control: The high and low temperature all-in-one machine supports the programming of temperature programs, and the temperature change curve can be set according to the process requirements.
   •Remote monitoring: The equipment supports remote monitoring and data recording functions, which is convenient for operators to monitor the reaction process and conduct data analysis.

3. Temperature regulation:
   •Precise control: The high and low temperature all-in-one machine can monitor the temperature in the reactor in real time through the temperature sensor, and automatically adjust the temperature and flow of the heating or cooling medium through the temperature control system such as the PID controller to achieve precise temperature control.
   •Quick response: The equipment can quickly respond to the needs of temperature changes, quickly heat or cool the materials in the reactor to adapt to changes in the process.

In summary, the refrigeration and heating circulator provides precise temperature control for the reactor through the circulation of heating and cooling media, combined with advanced temperature control systems and safety protection measures, to ensure that chemical reactions are carried out under ideal temperature conditions. This equipment is widely used in chemical synthesis, pharmaceuticals, materials science and other fields, and is of great significance for improving reaction efficiency, product quality and production safety.
