Description
The Caloritech™ A29 FS Series Finned Strip Heaters are industrial-grade electric resistance heaters engineered for efficient air heating applications. The heating element assembly is encased in an aluminized steel sheath, compressed under high pressure to enhance mechanical strength, corrosion resistance, and thermal conductivity. Steel fins are mechanically bonded to the sheath to increase surface area and improve convective heat transfer, making these heaters suitable for duct heating, oven heating, enclosures, and process air systems. The standard maximum sheath temperature is 1000°F (538°C). Units are available in multiple watt densities, voltages, and lengths, with optional accessories for enhanced electrical safety and installation flexibility.
