Laboratory Heater/Chiller for Jacketed Reactor

 

The cooling and heating units of the jacketed reactor are key components of its temperature control. They ensure that the materials in the reactor react effectively within a specific temperature range. The working principles of these two units are as follows:

 

Laboratory Heater/Chiller for Jacketed Reactor

 

Heating unit

1. Steam heating: A common method is to heat the jacket by filling it with steam. This usually requires an external steam boiler as a steam source. The steam circulates in the jacket and transfers heat to the materials in the reactor. The heating efficiency is high, but the initial hardware investment is large.

2. Electric heating: In some small or low-speed applications, the reactor may be equipped with electric heating elements, which are directly embedded in the jacket or fixed to the outside of the reactor. Electric heating has a fast response and is easy to control, but the operating cost is relatively high.

3. Heat transfer oil circulation: Heating is achieved by circulating heat transfer oil through the coils in the jacket. Heat transfer oil has good thermal stability and can effectively transfer heat over a wide temperature range. This method is flexible to control and heats evenly.

Refrigeration unit

1. Cold water circulation: The refrigeration unit usually uses cold water or refrigerant to circulate in the jacket to absorb the heat inside the reactor to achieve a cooling effect. Cold water can be supplied by an external refrigerator or chiller, and the temperature is adjustable.

2. Refrigerant circulation: Similar to thermal oil circulation heating, but using low-temperature refrigerants, such as Freon or other environmentally friendly refrigerants, to circulate in the coil to extract heat and achieve rapid cooling.

3. All-in-one cooling and heating machine: Some high-end jacketed reactors are equipped with all-in-one cooling and heating machines, which can quickly switch between heating and cooling. Through advanced control systems, the temperature in the reactor can be accurately controlled to meet the complex requirements of temperature changes during the reaction process.

Temperature control system

Whether heating or cooling, jacketed reactors are usually equipped with temperature sensors and automatic control systems (such as PID controllers) to monitor the temperature in the reactor in real time and automatically adjust the working status of the heating or cooling unit to maintain the set temperature point to ensure the stability and repeatability of the reaction conditions. The selection of the control unit needs to consider factors such as control accuracy, response speed and ease of operation to meet different experimental or production requirements.
