Car Bottom Furnaces

ITS designs, builds and installs car bottom furnaces for companies in the aerospace, oil drilling, steel, automotive, military and other industries.

The design of a Car Bottom Furnace incorporates a rail mounted product car to transfer parts into and out of the furnace. Our car bottom furnaces deliver unparalleled results for processing large and heavy industrial materials, from welded fabrications and forgings to spun products and plates. We have earned a reputation for excellence in heat-treatment of large and heavy welded fabrications such as gear blanks, oil drill pipe, drive shafts, and similar type products.

Why ITS?

Our clients that have built a new facility, upgraded or replaced a unit with an ITS car bottom solution have found that ITS’ engineering expertise, attention to detail, and “just right” pricing is a winning combination.

From executive offices concerned about return on investment and customer satisfaction, to operations and floor managers seeking durability, minimal down time and multiple applications, the ITS TruTemp™ Car Bottom Furnace delivers more than just promises. We deliver results.
