Energy Processes
Decarbonization efforts worldwide,led both by industry leaders and legislation, have increased efforts to shift fossil fuel use to renewables. One way many industrial o industrial organizations can embrace this- and already have- is by shifting process heaters systems from fuel-burning to electric.
Typical customer specifications for a direct electric heat exchanger (DEHE) in forced convection gas applications aim for efficiency and safety given the technology principles that have been in place for the last two decades. While the older specifications are conservative and safe, the design may be sub-optimal.
Electric process heaters that interface with flammable materials in explosive environments need to be properly evaluated to protect the equipment against catastrophic failures. A temperature class requirement will be provided by the user based on the explosive gases that may be present in the installation area. Click to read.
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.
By using HELIMX™ circulation heaters in its BPA processing, a manufacturer was able to widen its maintenance window by two to three times what it traditionally has been, saving both time and money. Read more
