Kleenair provide some of the best and most dependable batch furnaces on the market today. Exclusive, proprietary features give them unrivaled performance and usability for easy and reliable operation in even the most challenging applications. All our batch furnaces meet NFPA 86 and OSHA requirements.

High Performance Door Components

We manufacture the industry’s best door seals, door hinges, and door actuators. These components play a huge role in the performance and temperature uniformity of a batch furnace, and, while our door components are often imitated, they’ve never been duplicated. For reliable thermal seals, durability, and fast, easy action, Kleenair’s furnace door components can’t be beat.

Advanced Controls Systems & HMIs

All of our custom batch furnaces include advance control systems for outstanding ease of use. Customized HMIs (human-machine interfaces) provide all the control capabilities your process requires, with no extraneous features that you’ll never need or use. Engineered for intuitive operation, our control systems can also be connected to your facility’s computer network for remote use.

Automated load manipulators and other material handling systems can be included in your custom batch furnace for improved usability, productivity, and versatility.

Reliable Temperature Uniformity

Our batch furnaces provide high temperature capabilities, up to 3,250°F (1,800°C). As your application requires, they can be engineered for Class 1 through Class 5 temperature uniformity.

  • Class 1: temperature uniformity of ±5°F
  • Class 2: temperature uniformity of ±10°F
  • Class 3: temperature uniformity of ±15°F
  • Class 4: temperature uniformity of ±20°F
  • Class 5: temperature uniformity of ±25°F

Types of Custom Batch Furnaces and Ovens

Custom Car Bottom Furnaces

Car Bottom Furnace

Car bottom furnaces are ideal for processing very large/heavy parts that are loaded via overhead crane. A wheeled car (or cars), riding on floor-mounted or embedded rails carries the load into and out of the furnace.


Custom Box Furnaces & Box Ovens

Small Gas Fired Box Furnace

Box furnaces offer versatility for processing materials of all shapes and sizes. Single or double overhead lift doors make it easy to load and unload materials for processing. 


Custom Clamshell/Tip-Up Furnaces

Tip-Up Heat Treat Batch Furnace

With a lid that tips back for very fast loading and unloading, tip-up furnaces are a perfect solution for high temp quenching applications. Our proprietary high speed actuators provide some of the fastest opening times available.

Custom Drop Bottom Furnaces

Automated Drop Bottom Furnace with Quench

Our drop bottom furnaces are specially designed for solution heat treating of aluminum and other similar processes. High speed sliding doors and powerful, self-contained elevator systems allow treated materials to be fully lowered into the quenching bath in as little as 10 seconds.
