Process Heaters

Thermocouples and RTDs can become damaged and incorrectly read the current and temperature of your heating products. If you have unusual temperature fluctuations or temperature differences between multiple heater bundles, a replaced or repaired sensor can restore your heating process to optimal performance.

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.

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.
