Industry Interest in Electric Heaters Continues to Heat Up
November 06, 2023
Process electric heaters are an intriguing alternative to fuel burning heaters like the shell-and-tube exchangers commonly used in industrial plant settings. Electric heating elements, rather than heated fluid in tubes, provide constant heat flux. Electric heaters can thus control duty more precisely and produce higher heat fluxes than steam condensers. Since...
