How to Choose a Recirculating Heater/Chiller?

Recirculating Heater/Chiller is a refrigeration, heating and temperature control equipment that provides cold and heat sources for reactors in the pharmaceutical and chemical industry. In order to ensure the success of the chemical reaction process, it is necessary to choose a Recirculating Heater/Chiller that suits you.

1. Understand the temperature requirements of the reactor

The reaction temperature is usually determined by the physical and chemical properties of the desired product, as well as the reaction rate and other factors. In some cases, the reaction temperature has to be kept within a very narrow range in order to obtain suitable product properties. Therefore, when choosing a Recirculating Heater/Chiller, make sure that the equipment can provide the required temperature range and accuracy.

2. Understand heating and cooling methods

Recirculating Heater/Chiller uses heating method to heat the reactor and keep the temperature within the required temperature range. Traditional heating methods include electric heating wire, heating oil and steam. However, for some reactors, it may be necessary to use refrigeration to bring the temperature down to the desired range. Refrigeration methods generally include liquid cycle refrigeration, refrigeration based on compressors or absorption machines, and refrigeration methods based on solid-state refrigeration technology. When choosing a Recirculating Heater/Chiller, please ensure that the selected equipment can provide the required cooling method and refrigerant to ensure the success of the reaction.

3. Understand the size and material of the reactor

The size and material of the reactor are also important considerations for choosing a Recirculating Heater/Chiller. The size of the reactor reflects the volume and the amount of heat required. The selected equipment must be able to meet the reaction volume requirements to ensure that the temperature can be maintained stably and rapidly during the reaction. Material selection is also important. Reactors are often made of different materials including glass, stainless steel, plastic and corrosion resistant materials. Each material has its advantages and disadvantages. Therefore, when selecting a Recirculating Heater/Chiller, factors such as thermal conductivity and heat capacity of the selected material must be considered.

4. Understand the operation of Recirculating Heater/Chiller

It is also very important to consider operating and control requirements when selecting a Recirculating Heater/Chiller. The operation of the equipment needs to be convenient so that the temperature can be monitored and adjusted in time during the reaction. At the same time, the controller of the equipment must be very sensitive and reliable to ensure accurate temperature control.

It is very important to select the appropriate Recirculating Heater/Chiller for the production process of the chemical and pharmaceutical industry. When selecting, refer to the temperature requirements of the reactor, heating and cooling methods, the size and material of the reactor, and the operation and control requirements.
