Custom Heavy-Duty Continuous Furnaces and Ovens

Continuous heat treatment furnaces are primarily used to reheat semi-finished products, including slabs, blocks, billets, and other materials by utilizing three heat-treatment zones within the furnace. The semi-finished products 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.

At Kleenair Products, we have been engineering and manufacturing high performance, high capacity continuous furnaces and ovens for numerous types of industrial applications for over 50 years. All our continuous furnaces are completely custom-designed and –built to meet our customers’ unique performance requirements.
