Series FSA

PROTHERM, LLC™ Series FSA heaters are highly efficient, fast response, medium wavelength, electric infrared heaters with air flow designed for use in general industrial process heating and drying applications for sensitive products such as coatings on webs or textiles.

Airflow is directed through holes between heating elements to help break up vapor barriers from evaporating moisture.  This increases the infrared drying efficiency and can help quickly cool the heater and product upon a line stop.  The air supply can be provided from a variety of sources that is appropriate for the application.
