Delta-Tube - Mica Band Heaters

This thin profile construction allows high watt densities up to 55 watts per square inch and quick heat transfer from the element to the sheath for efficient operation up to 800 degF sheath temperature. A stainless steel sheath encases a compressed mineral refractory which surrounds a helical or sinuated resistance element. We also offer band heaters up to 200 WSI. Contact us. With SCR or SSR power control output, watt densities can be increased up to 30%. Mica band heaters are economical, thin, efficient heaters up to 800 deg F.
