Bayonet Heaters

Efficient & Cost Effective

The engineers at Enerquip know it’s crucial to properly heat your process liquids. Using the wrong method could result in ruined product and wasted energy, time and money. This is why we work with our customers to find the best solution for their heating needs. In addition to the many styles of shell and tube heat exchangers Enerquip offers, we also provide a line of bayonet heaters. Designed to efficiently heat entire tanks of fluid, our bayonet heaters efficiently transfer heat to large quantities of liquids, making them cost-effective for temperature regulation of process solutions, oils, and more.

Unlike our shell and tube exchangers, which are designed to heat liquids as they are pumped through the exchanger, bayonet heaters are designed to efficiently heat entire tanks of fluid. The tube bundle is completely immersed in the tank and the heating coil is directly exposed to the fluid.

Enerquip’s bayonet heaters are easy to install and don’t take up any extra space. As immersion heaters, they are inserted directly into the liquid through a tank flange, resulting in space and energy efficiency. Sitting inside the tank holding the liquid and fastened to the tank itself, the only equipment needed for the installation is a utility hookup.

Bayonet style tank heaters are typically inserted from the side of the tank. They are made of a tubesheet, tube bundle and a bonnet with utility connections. Customers typically like using bayonet heaters because they can be easily removed for cleaning and inspection. Pre-existing flanges and manways on the tank are great for installation, eliminating the need to retrofit a tank or purchase a new one.

Enerquip prides itself on providing quality and cost-effective solutions to its customers. Our bayonet heaters reflect these points as they are a practical way to heat nearly all types of liquid. All of our bayonet heaters are fabricated with stainless steel, a material highly resistant to corrosion, giving our equipment a long lifespan.
In addition to our standard models, we can provide equipment customized to your specifications. Regardless of which option you choose, your equipment will arrive quickly and safely to your site.

All of our equipment is built according to industry standards. We will work with customers to make sure that the products they purchase meet the material and finish requirements needed by their particular industry.

A Case Study in Bayonet Heaters


For the past three years, Lamberti has worked with Enerquip to customize shell and tube exchangers for its operations. Looking to invest in an immersion heater, they called upon their friends at Enerquip upon hearing about our new line of bayonet heaters.

The liquid that Lamberti needed to heat was being stored in vessels. After talking to Enerquip, Ruder learned that the manways located at the top of the vessels were perfect for Enerquip’s bayonet heaters. The bayonet heater could be attached at the manways, which would allow for easy removal when needed. Ruder explained this is necessary because Lamberti’s policy states that equipment must be inspected periodically.
