FINBAR™ Single-Ended Heaters
Composed of aluminized steel fins press fitted to a
one-inch single-ended FIREBAR element. The FINBAR™
is designed to improve heat transfer to the air and
permits putting more power in tighter spaces—like forced
air ducts, dryers, ovens and load bank resistors.
Heat transfer, lower sheath temperature and element life
are all maximized by its finned construction. Installation
is simplified by terminations exiting at one end and
mounting accommodations on both ends.
Watlow FINBAR™ Tubular Finned Air Heater |
Performance Capabilities
• Watt densities up to 50 W/in2 (7.7 W/cm2)
• 304 stainless steel sheath temperatures up to
1200°F (650°C)
• Voltages up to 480VAC
• Amperages up to 48 amperes per heater or
16 amperes per coil
Features and Benefits
Rugged aluminized steel fins
• Provides an increase in surface area to approximately
16 square inches for every linear inch of element
length. Fins press fitted to the heating element
improve heat transfer to the air
Single-ended termination
• Simplifies wiring and installation
Stainless steel mounting bracket, welded to the
terminal end, supplied with a slotted end
• Allows ease of installation
Lavacone seals
• Provides protection against humid storage
conditions, moisture retardant to 221°F (105°C)

Typical Applications
• Forced air heating for dryers, ovens, ducts
• Still air heating for ovens, comfort heating
• Incubators
• Ink drying
• Load bank resistors
Application Hints
• Avoid deteriorating the fins by not exceeding the
recommended maximum fin temperature of
1100°F (600°C).
• Ensure proper air flow to prevent premature
heater failure.
• Locate the temperature sensor downstream from
heater(s) for process temperature sensing.
The following mounting parameters are recommended:
• Air flow over element must be parallel with the
flat side.
• Element center line to element center line spacing
must be a minimum of 11/2 in. (38 mm).
Part numbers range from 10.25 inches to 47.75 inches in length.
Wattage range from 300 Watts to 4000 Watts with two watt densities.
20 W/in2 and 40 W/in2
Watlow FINBAR elements are rated in both 120 volt or 240 volt versions.
