(PTFE) Teflon Immersion Heater is a tube-shaped, heavy-duty, industrial joule heating element (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Highly compacted they reach a surface watt density of up to 30 w/cm².
It may be used to heat any kind of substance or material, such as oil, air, or sugar. However, a common application is plastic pellets, which are melted in order to form molded plastic parts. An example of such a process is the “hot runner” process. (PTFE) Teflon Immersion Heater resemble tubular heaters structurally but tend to have higher watt densities.
Teflon Immersion Heater Features:
* Rugged construction prevents floating.
* Flame retardant, vapor tight, polypropylene terminal box.
* Stainless steel elements with TEFLON cladding.
* Internal metal ground.
* Heater element extends horizontally along tank bottom, providing superior heat distribution.
* Vertical portion above horizontal call is not heated.
* Longer vertical lengths available-consults factory.
* Single phase or three phase.
