Custom Continuous Furnaces & Ovens

Continuous furnaces are primarily used for heating metal billets before they are rolled, forged, or stamped. Within the inner structure of continuous ovens and furnaces the billets are arranged crosswise and move in the opposite direction of the area of fuel combustion. This type of design allows the heat within the furnace to be used more effectively and efficiently.

Engineered Heavy Duty Design, Built to your Exact Specifications.

Kleenair Products Co. are the proven experts in custom continuous furnaces and continuous ovens. For more than 50 years, we have been engineering and manufacturing high performance, high capacity continuous furnaces and ovens for numerous types of industrial applications. All of our continuous furnaces are completely custom-designed and –built to meet our customers’ unique performance requirements.

Contact us for more information on the custom continuous furnace or oven system that best suits your specification requirements or call us at 800-275-5152 and we will be happy to assist you with your continuous oven and furnace questions. We are the world’s foremost industrial oven manufacturers.

Continuous Oven & Furnace Operational Qualities

A continuous oven or furnace functions by utilizing three heat-treatment zones. The billets consecutively pass through each of these zones, allowing for proper preheating, heating, and soaking. Each section contributes to the overall heating success of the continuous furnace or oven. The temperature in continuous furnaces is constant over time and variable over the length of the furnace. In the heating and soaking zones, the temperature is almost constant; in the holding zone it decreases toward the front of the furnace.

Continuous Furnace Advanced Features & Controls for Enhanced Usability

Kleenair’s continuous furnaces and ovens are among the best and most dependable on the market. With a host of exclusive, proprietary features, these furnaces deliver unparalleled performance and usability in even the most demanding applications. All of our continuous ovens and furnaces meet NFPA 86 and OSHA requirements.

Robust Conveying Systems & Support Structures for Continous Ovens and Furnaces

The conveying systems and related support structures of our continuous furnaces/ovens feature heavy duty design and construction. These systems incorporate sturdy bearings, rollers, and supports for reliable loading and unloading of materials.

As needed, Kleenair can also provide automated material handling systems for the load and/or unload side of your furnace or oven. We can incorporate custom robotic material handling solutions that are designed to meet your specific requirements, or provide off-the-shelf modules from Fanuc, Siemens, and other top robotics manufacturers.

Premium Quality Door Components for Continous Furnaces 

A continuous furnace’s door seals, door hinges, and door actuators play a key role in its performance and temperature uniformity. Kleenair manufactures the industry’s best furnace door systems. All our continuous furnaces and ovens benefit from the reliable thermal seals, durability, and fast, easy action of our often-imitated, never-duplicated door technology.

Innovative Controls & HMIs for Continous Furnaces and Oven Furnaces 

Every Kleenair continuous furnace and oven features an advanced control system for unmatched ease of use. Our customized HMIs (human-machine interfaces) provide all the control capabilities your process requires, with no unnecessary features that you won’t use cluttering up the control panel. Engineered for intuitive operation, our control systems can also be integrated with your facility’s computer network for remote use.

Material- and part-tracking systems can be incorporated into your custom continuous furnace, as needed. Our tracking technology lets you follow the workpiece through the entire process, while providing recordable and verifiable process information for every piece that exits your furnace.

State-of-the-Art Combustion Systems & Reliable Temperature Uniformity

Because a continuous furnace is always firing, fuel and energy savings are important. Kleenair’s advanced combustion systems reduce the cost of heating your furnace, while proven insulation techniques minimize heat loss and help maintain a consistent internal temperature. Our continuous ovens and furnaces conform to AMS 2750 standards for temperature uniformity.

Continuous Furnace & Oven Applications

Continuous ovens and furnaces can be used for several different types of applications. They are specifically designed to adjust to your exact design specifications. Some of the applicable uses for continuous furnace and ovens, include:

  • Metal injection molding 
  • Atmospheric controls 
  • Glass 
  • Annealing 
  • Brazing 
  • Metallizing


Types of Custom Continuous Furnaces and Ovens

Rotary Hearth FurnaceCustom Rotary Hearth Furnaces

A rotary hearth furnace features a rotating worktable inside that carries workpieces from the load door the unload door (a single door can be used for load/unload, if preferred). Temperature and rotational speed can be modified to match your process requirements.


Roller Hearth FurnacesCustom Roller Hearth Furnaces

In a roller hearth furnace, motor-driven rollers for a “conveyor belt” to transport workpieces from the load door to the unload door, at the ideal speed for your unique process. Kleenair’s heavy duty roller bearings are designed to minimize load for long working life.


Walking Beam FurnaceCustom Walking Beam Furnaces & Ovens

Kleenair walking beam furnaces and ovens use an automated, multi-rail “walking beam” system to move workpieces through the process area one step at a time. Robust designs and engineering ensure reliable, consistent movement and precise heat times.


Hydrogen Atmosphere Pusher Sintering FurnaceCustom Pusher Furnaces & Ovens

Our pusher furnaces and ovens are capable of operating at the highest temperatures of any of our continuous furnaces. Parts or materials are placed on trays, which are then pushed through the furnace on rails by hydraulic or pneumatic cylinders for reliable processing.


Kleenair Continuous Furnace Features

While each of our custom continuous furnaces and ovens is designed for a different application, they all provide the following advanced quality feature:

  • High capacity work envelopes
  • Refractories specially designed for extremely high operating temperatures
  • Heavy duty conveying systems and supports
  • The industry’s best door seals, door hinges, and door actuators
  • Natural gas or electric heat
  • State-of-the-art control systems/HMIs for enhanced usability
  • Heavy duty construction for durability and longevity
  • NFPA 86 and OSHA compliance
