Selas Heat Technology, Streetsboro, Ohio, USA, has introduced the new Red-Ray™ High Intensity Gas-fired Infrared Emitter, designed exclusively for paper drying. Using less energy than current emitters on the market, Selas’ latest innovation reduces energy costs, lowers emissions, and increases production.  

This new technology uses a unique 3D printed Siliconized Silicon-Carbide (Si-SiC) lattice design that enables the emitter to reach an industry leading maximum temperature of 2,450 °F (1,350 °C), giving mill operators the flexibility to increase throughput or decrease energy usage. The emitter’s rated capacity is 40,950 BTU/hr (12 kW). The structure and increased surface area of the lattice, combined with the near perfect "black body" emissivity of Si-SiC, provides a best in class radiating surface resulting in higher radiant energy.

Complete combustion within the cell structure of the lattice results in no open flames, producing the lowest NOx profile for emitters in the industry.

The Red-Ray High Intensity Infrared Emitter provides unmatched start up performance reaching operational temperatures in approximately 60 seconds and cooling down to below the ignition point of paper in 10 seconds.

This durable emitter is constructed without a metal screen for high tensile strength and is resistant to water and coating splashes. The Red-Ray High Intensity Infrared Emitter is designed to mount directly to the existing mixing tubes of all leading infrared systems. Common applications include paper drying and coating drying.
