5 Key Advantages of Horizontal Steel Storage Tanks

Steel tanks aren’t one-size-fits-all. Oftentimes, this means having to spend time researching tanks to determine what shape and size is right for your storage and transportation needs.

Horizontal steel storage tanks offer many advantages, including being more efficient and more affordable to transport.

Horizontal tanks are often used within the agricultural and beverage industries because they are best suited for storing liquids like water and chemicals. Thanks to their shape, horizontal steel storage tanks are much easier to transport and move than vertical tanks. This easy mobility makes horizontal tanks very appealing for those who need to house or transport liquids on a regular basis.

2. Height is No Longer a Factor

If you’re facing height restrictions in your plant, factory, or vehicle, a vertical tank may cause more trouble than it’s worth.… Read more

A production manager and her assistant evaluate the performance of used stainless steel tanks and equipment.

So, you’ve just landed a private label or contract manufacturing account for a new client who wants to ramp up quickly.

One of the most common questions we get at Zwirner Equipment is “which stainless steel tank do I need?”

In our last two blog posts, which are Part 1 & 2 of this 3-Part series, we discussed how to choose the right stainless steel tank for your application based on shape and space and heating and cooling. In this post, we are going to discuss how to choose the right tank based on agitation needs.

Do you need agitation?

Agitation is the action of stirring, mixing or moving a product within a vessel. It is used primarily to keep your product moving. Almost all products that use heating and/or cooling will need some form of agitation. Components of agitation always include a shafted blade, gearbox and motor, which can be customized to the speed you need to mix. These components must fit the RPM and horsepower that is required to achieve a higher or slower rate of speed and torque.… Read more
