This series of high efficiency electric infrared heaters emit infrared energy across a broad band of medium to long wavelengths. Such wavelengths are easily absorbed by most products and accomplish predrying, drying, curing, preheating and other process heating tasks. Radplane® industrial infrared heaters offer a high conversion efficiency of electrical power input to usable infrared energy, saving operating costs. Resistive metal infrared heating elements are mounted on high temperature insulation backings and radiate directly at the product for efficient radiation heat transfer. Our infrared heating elements are made of corrugated ribbon foil, expanded metal or sinuated wire (Series 8038), depending on the electrical configuration and energy requirements of your application. Our open element heater design, without ceramic, quartz or glass faces inhibiting the transfer of energy to your products, deliver rapid starts using less energy. The heater elements heat and cool very rapidly; reaching typical operating temperatures in just a few seconds and dropping below any destructive surface temperature just as quickly when power is shut off- thus the name "Rapid Response". Often our heater designs include integral air flow (Series 82/85) to assist in drying applications. For wider products, flexible element spacing and the ability to form edge and center zones (Series 81) assure uniform heating across machine direction. When coupled with closed loop feedback controls, the heater element or product temperature is precisely controlled to give consistent and high quality results.
