Different Types of Jacketed Tanks

Jacketed vessels play a vital role in maintaining temperature control and product quality in various industries. Without these jacketed vessels, companies could incur losses due to spoilage. There are multiple types of jacketed tanks you can use in your business or organization.

What Is a Jacketed Tank? 

A jacketed tank is a container or vessel that has a secondary outer shell. The outer shell is known as the jacket, and it surrounds the main tank and allows the circulation of temperature-controlled fluids. Through these fluids, the jacket maintains precise temperature control in the tank. It’s like a thermos that wraps a container in a second layer to regulate the temperature of the contents. The jackets are either strapped or welded to the container. 

Jacketed tanks typically use steam, liquid nitrogen and other chemicals to regulate temperature. They can be used for cooling, heating and mixing liquids. They can also be used for storing and transporting products. 

Jacketed vessels have multiple design variations to accommodate different applications and industries. For example, the food industry uses jacketed stainless steel tanks for tempering chocolate and sugary confections. 

Types of Jacketed Tanks 

As a chemical engineer, plant manager or any other professional directly involved in handling products that require temperature control measures, you should know the appropriate containers to use. Stainless steel jacketed tank manufacturers design different types of tanks to serve different purposes. You can identify and choose the type that best suits your needs. 

1. Dimpled

A dimple jacketed tank has spaced indentations on the outer jacket to circulate a cooling or heating liquid. The dimpled sections are welded to the inner tank wall. The undimpled sections of the tank create space for the heat exchange medium to flow through. The tank is well-known for its efficient heat transfer and is excellent for applications that don’t require drastic temperature changes. However, this tank cannot be used for processes involving thermal shock because of its thinner layers.

The pitted sides of a dimpled jacketed tank reduce pressure drop and weight. Consider these tanks when you want lower media flow in contact points, improved steam applications and better liquid distribution. Dimple jackets are affordable and available in a variety of shapes, sizes and pressure ratings.

2. Half-Pipe

This jacketed tank features a welded, semi-circular pipe that runs on the exterior of the vessel. The pipe is welded into the inner tank wall, allowing the heat exchange medium to flow through the pipe. The design allows for higher flow rate than dimple jackets. 

This configuration provides robust heat transfer, making this type of vessel ideal for high-temperature and liquid heat transfer applications. These jackets are more expensive than dimple jacks. 

3. Conventional 

Conventional jackets, also known as double-wall jackets, allow workers to adjust the tank’s cooling and heating. The jackets use fluids like oil and water as their medium of exchange and transfer heat between the container and jacket. The jackets are installed around the container to create an annular space, or an outer and inner wall for the tank. The space or wall later fills with the fluids.

Conventional jackets achieve the lowest pressure drops of all jacket types. This feature makes double-wall jackets ideal for low-pressure operations.

Each jacketed tank is designed for specific applications. Understanding the types and differences between jacketed tanks will help you make the right choice.

Why Businesses Use Jacketed Tanks 

Various production processes have multiple steps requiring tanks to adjust or maintain product temperatures. Jacketed tanks provide a convenient solution for these precise adjustments and controls. These consistent temperatures boost product quality and yields by preventing unwanted fluctuations during processes. 

Jacketed tanks keep the containers’ contents at consistent temperatures. The tank heater jacket keeps the reservoir’s content flowing without interaction with other composites. Your vessels need tank jackets because of temperature fluctuations from environmental changes. The tank sleeve prevents containments from leaking and improves moisture buildup. 

The jacketed vessels are also designed to handle high-temperature processes safely. The use of these vessels in industrial processes reduces the risk of large-scale accidents. 

Industries That Use Jacketed Vessels 

Jacketed tanks are widely used in the following industries. 

1. Food and Beverage Production

Jacketed vessels, such as stainless steel jacketed tanks, are used extensively in the food and beverage industry. The vessels are used in processes like fermentation, cooking and pasteurization. The jacketed tanks help maintain temperatures critical for product quality and safety in the industry.  

Jacketed tanks are used for fermentation and conditioning in the brewing industry. Brewers can control temperatures and optimize the fermentation process using the vessels. 

2. Oil and Gas

Jacketed tanks in the oil and gas industry keep the temperatures of the tanks’ contents consistent. They prevent the content inside from interacting with the outside. 

3. Chemical Processing

Jacketed vessels are vital in the chemical processing industry. They help control temperatures during chemical reactions and mixing processes. These controls enhance product safety and consistency. 

4. Health Care and Pharmaceuticals

The pharmaceutical industry relies on jacketed tanks for crystallization, reactions and sterilization processes. Precise temperature controls help maintain the integrity of pharmaceutical products.

5. Mining

Jacketed tanks in the mining industry help regulate containers’ contents and minimize the chance of insulated fires. 

Applications of Jacketed Tanks

Jacketed tanks have multiple applications, including:

• Cooling and storage: Overheating can cause products to expire, denature or spoil. You can prevent these conditions using jacketed vessels and extend the life span of the products. 
• Viscosity: Jacketed tanks are used to support homogeneous viscosity customized to your precise needs.
• Reaction temperatures: Different reactions have different optimum temperatures for productivity, whether endothermic or exothermic. You can set your vessels to these temperatures and effectively maintain them.
