Series F

PROTHERM, LLC™ series F heaters are highly efficient, fast response, medium wavelength, electric infrared heaters designed for use in general industrial process heating applications where critical product temperatures and uniformity are demanded.

Series F corrugated foil elements respond slightly faster than series FS elements due to the thinner material thickness. However having limited resistance options and requiring longer element circuit length limits the design options we can offer. In most applications, we recommend using the PROTHERM series FS as an alternative. Please contact a PROTHERM heater design specialist to see if Series F can be a good option for your application.
