Selection Guidelines

The metal-sheath type heater is easily installed and may be operated in any position. The units may be mounted to form banks, tunnels or oven sections. Chromalox offers heaters in two standard intensities. 1.83 kW per sq. ft. — type RAD. Adequate intensity for about 80% of all applications including finish curing.

3.66 kW per sq. ft. — type RADD, U-RAD and U-RAD-LT speed up webfed and conveyorized operations in which excessive temperatures will not cause damage. Examples are water dry-off, shrink fitting and weld preheating.

Liquid-tight housings are available for single and double hairpin designs where moisture resistance is desired.

Quartz lamp and Quartz tube have faster heat and cool down cycles for higher speed process applications.

Wide area panels can give a wide, flat infrared radiation pattern where needed.
