High Intensity Heaters SWL

The SWL Unitube provides energy efficiencies of up to 85%, drastically reducing electrical power consumption over competitive tubular heaters.

Like all Casso Solar Infrared Heaters®, the SWL Unitube can be tuned to match the peak absorbtion point of the material being heated over the usable wavelength range of 0.76-4.0 microns, with emitter temperatures of up to 5000°F.

SWL Unitubes can be arranged to provide temperature profiling, or can be shut down to conserve energy with narrow products or when there is no product in the oven.

Shortwave energy penetrates into most products to provide uniform heating through the product’s thickness.
