HE-Tubular Sheathed Tubular Heater
Industrial tubular heaters for immersion, air, and process fluid heating.
SAWHEAT tubular heaters consist of a NiCr resistance coil packed inside a metallic sheath with compacted MgO powder insulation. The sheath material is selected to match the medium — incoloy for high-temperature air, stainless steel for liquid immersion, and copper for non-corrosive liquids.
