Petrochemicals often require certain temperatures in order to maintain its viscosity in process applications as well as in harsh external environments.
Flanged heaters are often chosen in order to apply a relatively moderate heat source that can penetrate the heavy lubricant evenly across the containment. Bitumen often uses flanged heaters to help with the extraction process in the oil industry.
Circulation heaters are used when circuits of flowing liquid exist and users are looking for minimal heat applications. The liquid starts off at ambient temperatures but the residual heat that already exists in a well insulated circuit is assisted with bursts of gradual cyclical heat from a heat source: the flanged heater.
Using precise instrumentation such as a thermocouple or an RTD, users can often reach the temperature required with efficient use of clean energy while achieving their goals. Control panels are also used with high limit controllers to help prevent higher temperatures that could result from caking material that stick onto the heating elements. Low watt densities assist with the preservation of heating elements but a good control that shuts off the elements in the presence of high temperatures is an effective means to preserve both the heated medium as well as the heat source: your WATTCO flanged heaters.
