Industrial Infrared Heaters

Radiant heat has become the preferred process heating method for a multitude of industrial applications due to the unique properties and significant advantages of infrared heaters. Infrared heaters create radiant energy to directly heat the product as opposed to a convection oven which is dependent on-air circulation as the heat transfer medium. By eliminating the air medium, radiant heating also reduces the losses associated with hot air ovens, and as a result, most products can be heated much more rapidly than in a convection oven.

Since infrared is not dependent on air as the heat transfer method, the air circulation in an infrared process is kept at a minimum. Powder coatings and light-weight materials can be heated rapidly due to low volume of air and low velocities. Because infrared heat can be easily controlled and directed, heaters can be "zoned" to provide a high heating zone in one zone and a lower heating rate in another.

Infrared heaters are very responsive to control changes; accurate and consistent product temperature control to within extremely close tolerances are possible.


Our Products Include

Metal Sheathed Radiant Heaters

These heaters are an extruded aluminum housing that contains one double hairpin-bent radiant heater in center, flanked by up to three (3)U-shaped elements. Movable mounting clamps and bolts are supplied to accommodate many mounting configurations such as banks, tunnels, and oven sections. Radiant heater output may be controlled with SCR Power Controllers, Percentage Timing Input Controls, and Non-Contact Temperature Sensors. Designed for long life, the element is more resistant to hard blows than quartz lamp or tube and open coil types and is also available in a hermetically sealed version.

Metal Sheathed Radiant Heaters

Radiant Panel Heaters

Wide area radiant heaters can be mounted to radiate in any direction and can reliably operate with no reduction in radiant output over the life of the heater. The lightweight building block approach allows for a modular installation, which is easily expandable.

Radiant Panel Heaters

XRM Series Heaters

Industrial stainless-steel infrared heaters provide fan-free warmth for permanent supplemental, spot heating where dependence on air movement is impractical. Best utilized in open areas like repair bays, walkways, assembly areas, foundries, and loading docks, these high-output heaters can be mounted in any orientation. High-watt density and industrial design provides a durable source of heat with optional safety grilles and a sealed wiring compartment that allows units for washdown.

XRM Series Heaters

High-Efficiency Gas Tube Infrared

Series KMI high-intensity infrared heater has a radiant factor up to 81%, which provides significant energy savings and high thermal comfort. The heater utilizes 100% insulated reflectors, which prevents convective heat loss along with "high-grid" technology that improves heat yield.
