Heat Transfer In Jacketed VesselsA jacketed vessel is a container that is designed to allow accurate control of the temperature of its content. The jacket that surrounds the container vessel is used to circulate fluid that either heats or cools the container and is designed to ensure a uniform exchange of heat between the circulating fluid, the vessel’s walls and the content that is being processed.

There are several types of jackets: Conventional Jackets, Half-Pipe Coil Jackets, Dimple Jackets and Plate Coils.

Jacketed vessels can also be employed as chemical reactors - to remove the elevated heat of reaction - or to reduce the viscosity of highly viscous fluids such as tar. Agitation can be also used in jacketed vessels to improve the homogeneity of the fluid’s properties (such as temperature or concentration).

Delta T Systems’ temperature control units are connected with pipes or hoses to a vessel’s jacket to form a closed loop; this ensures that the heat transfer fluid (water or oil depending on temperature requirements) never mixes with the ingredients being processed.

Many applications require both heating and cooling. A batch of product might be brought up to a temperature set point, i.e. 200°F, and then  a quick cool down might be required at the end of the process. In such cases, a chiller is connected to a temperature control unit to provide some cooling water for this final part of a process.

Jacketed Vessels are commonly used in the following industries:

Delta T Systems’ temperature control equipment is designed and tested for various applications that require temperatures ranging from 20°F to 650°F. With precise and consistent temperature control, manufacturers can produce higher quality and higher quantities per batch.
