Technical Data
   
   

High Density Strip Heaters are constructed with a highly compacted refractory insulation that quickly conducts heat from the resistance wire to the sheath resulting in low internal temperatures and long heater life in the most demanding applications. Precise placement of the resistance wire provides uniform sheath temperature across the width and along the entire heated length. HD strip heaters are 3/8” thick and provide a rigid sheath for secure clamping to flat surfaces. There are three terminal options to allow for easy installation wiring. This is an extremely rugged construction capable of high temperatures and high watt densities.

FINNED STRIP HEATERS

Finned HD Strip Heaters feature the same highly compressed, rugged design as HD Strip Heaters with the addition of 1-3/8" X 2" fins. Fins increase the heat transfer surface area to allow higher wattages than standard HD Strip Heaters. Rust resisting iron sheath items (HDA) are standard with aluminized steel fins. Stainless steel sheath items (HDS) are standard with stainless steel fins. These are intended to be operated with a substantial airflow and are typically used in heating tunnels, dryers or any application that requires a hot air source.
