| Vessel Materials | Carbon steel Duplex Monel Low temperature steel Titanium Nickel alloys Stainless steel Super austenitic |
| 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 |
