FORMED TUBULAR HEATERS
Durex Industries manufactures formed tubular heating elements for applications which require a uniform heat source over a distributed area. Tubular heaters can be designed with wide range diameters, lengths, sheath materials and voltage ratings. The flexibility of these heating elements is said to allow them to be formed into virtually any shape, including precision forming for a tight fit into milled grooves of manifold surfaces. Multiple termination options are available depending on application requirements.
These options include threaded stud terminals, flexible lead wire or bulkhead fittings. Customized terminations are available for harsh or high-moisture environments. The sheath of the tubular heater is available in many materials and surface treatments, such as passivation or electro-polishing for increased corrosion resistance.
