Elements Manufactured from 80/20 NiCr resistance wire with high purity compacted magnesium oxide powder sheathed within corrosion / erosion resistant tube, eg:

Incoloy 800/825
316/316L stainless steel
Inconel 600/625
321 stainless steel
Titanium
Monel

Element sheath available in welded or seamless tube up to 1.6mm thick
Internals Elements are supported in a segmental or rod type baffle assembly to prevent flow-induced vibration and hot spots, generally complying with TEMA standards
Element to Tubesheet Generally, elements are sealed into the flange by ‘Bite’ type couplings which provide a 100% seal at pressures up to 400 barg and give the opportunity to replace individual elements on site; elements can be welded to the tubesheet, in stand-off and non-stand-off configurations
Terminal Box Manufactured from either iron or stainless steel
Voltage Suitable for voltages up to 690V
