Heavy Duty Strip Heaters

Chromalox High Density Strip Heaters are constructed using our own proprietary refractory cement and are highly compacted for excellent heat transfer. These are primarily used for convection type air heating and clamp on conductive heating. The strip heaters are available in a wide variety of widths and lengths. There are many different options for sheath material, terminations, mounting and electrical ratings. Depending upon sheath materials the compacted strip can obtain temperatures up to 1500°F (815°C). These heaters are highly suited for many industrial and commercial applications.

Strip heaters are used for heat transfer by conduction or convection to heat liquids, air, gases and surfaces. See guidelines in the Strip Heater Overview.
