SF & SFA Heaters

Anderson Thermal Devices, type SF/SFA, infrared SFA Infrared Heater
heaters, are highly efficient, fast response, medium wavelength heaters for a wide variety of industrial process heating applications.

Rugged stamped foil element strips are mounted on a high temperature insulation board. The energy freely radiates to the product without any quartz or ceramic to block the energy. This allows a 90% conversion of electrical power input to useable radiant output, eliminates thermal lag for very tight process control, and minimizes stored heat which causes damage to products on shutdown.

Type SFA heaters include 100 air jets per square foot which provide air impingement to assist in drying and provide instant cooling shutdown.

* Nominal size indicates the actual case width and actual heated element length. As an example:
12 x 24 is 12 inches wide and a 24 inch heated length element.

** Actual size indicates the actual outside dimensions of the heater case.
