F & FBA series heaters use a quartz composite cloth face, our most economical and largest selling model.
F and FBA Series Face Options
Quartz composite is the standard face on the F-Series heater. They are produced by a patented process that uses a high temperature material and special cement to bond the quartz fabric with a ceramic fibre coil support. The end result is a unique, highly durable, quartz composite face heater.
The F-Series heater gives a tremendous amount of flexibility. Its shape can be manufactured:
- rectangular (most common)
- square
- round
- C-shaped
To provide uniformity across wide web applications, heat can be aimed in a single direction (most common) or in dual directions.
The maximum watt density of 25 watts/in² (wsi) provides a sufficient amount of power for the majority of applications.
The proven design of the F-Series heater requires no external reflector, therefore maintaining a consistently high radiant efficiency throughout its life. The use of an external reflector in most infrared heaters results in a dramatic loss of radiant efficiency over time
F-Series heaters are used in most process heating applications and consistently prove to be the perfect heater for nearly all infrared heating, drying, and curing applications.
The only applications where it might not be used are vacuum applications and those in which materials could possibly damage the heater's face. F-Series Specifications
F-Series heaters can be manufactured as wide as 30" (762 mm) and as long as 84" (2133 mm), although not that width and length in the same heater. For example, an 84" (2133 mm) long heater is commonly not wider than 12" (305 mm).
This heater is very flexible in size and watt density options. It has a maximum watt density of 25 watts/in²(39 kW/m²) and a durability defined by a typical life expectancy of 25,000 hours.
The heater has a high radiant efficiency of 78.5%. Because its design does not depend on an external reflector, the heater maintains a high radiant efficiency over time.
The F-Series heat transfer rate for 25 watts/in2(39 kW/m2) is 2.4 Btu/ft2/sec. delivered to the product and for 12.5 watts/in² (19.4 kW/m²) is 1.15 Btu/ft2./sec. delivered to the product.
FBA-Series Specifications
The FBA series have holes drilled in the face in order to enable forced air to flow through the heater.
The purpose of the airflow can be either to protect sensitive material or components from being damaged by infrared heating, improve the drying process by gently sweeping moisture away, or to provide an infrared/convection heating combination.
The FBA model is manufactured with either 1/8" (3.2 mm) or 1/4" (6.4 mm) holes usually located 1" (25.4 mm) from the center.
The heater has no internal insulation in order to accommodate a 2"-5" (50.8-127 mm) typical plenum area in its cavity. It commonly has a back-mounted 3" (76.2 mm) hole for airflow. Smaller heaters have one hole, whereas larger heaters can have multiple holes.
The airflow can also be directed through the side or end of the heater casing in some applications. Individual high-temperature fans can be attached directly to these holes, or a centrifugal fan can be used with ductwork to supply the air to multiple heaters.
The airflow construction commonly has 20 to 50 cfm/ft².
Applications for the FBA model include:
- removing moisture
- operation in a secondary stage powder coating oven
- screen printing
- electronics
FBA-Series heater can be manufactured as wide as 24" (610 mm) and as long as 72" (1829 mm), although not that width and length in the same heater. For example a 72" (1829 mm) long heater is commonly not wider than 12" (305 mm).
This heater is very flexible in size and watt density options. It has a maximum watt density of 25 watts/in²(39 kW/m²) and a durability defined by a typical life expectancy of 25,000 hours.
The heater has a high radiant efficiency of 78.5%. Because its design does not depend on an external reflector, the heater maintains a high radiant efficiency over time. F-Series Panel Heater (Models: FB & FBA)
Heaters in the F-Series line of infared panel heaters have a very durable emitter surface constructed using a patented manufacturing process. The FB model has a solid flat uniform surface. Because the FBA heater has air holes drilled throughout its face, its insulation is removed in order to accommodate an air delivery plenum.

F-Series Warm-up Curve
The warm-up curves are measured from heaters running facedown in open air. The thermocouple is located in a standard location inside a thermowell behind the coil. The curves will change depending on the environment and thermocouple location.
