Fast Heat's versatile Tubular heaters are custom-formed in a wide range of shapes to correspond to your requirements.

Incoloy stainless steel or steel sheath materials are available, as well as a large selection of termination styles. Magnesium Oxide insulation ensures superior heat transfer and the resistance wire is precision-wound for long heater life.

Tubular heaters can be used in almost any application. Straight tubulars can be clamped to metal surfaces or inserted in machined groves for conductive heat transfer. Or use a formed Tubular to provide consistent heat in any type of special application.
