One of the most common failures in electric process heaters used in various industrial applications involves electrical terminations and not the heating elements. Engineers at Watlow® believe designers across the industry are underestimating the temperature profile from the heater flange to terminal enclosure in these thermal systems.

Companies in liquified natural gas (LNG) and other industries have been taking bold steps to reduce their carbon footprint. The overall strategy of these companies is to tackle carbon emissions not only through alternative energy investment and increased efficiency, but also through converting key industrial processes (like process heating) to electric (rather than fuel-fired). This paper explores pressures to electrify process heating, as well as the role that electric heat exchangers are playing, particularly in light of innovations in the design of these heaters.
