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

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

Maximum Operating Temperature: Sheath material:

304 SS, 1200°F (650°C), fin material; aluminized steel;

1100°F (600°C)

Heater Length: 11 to 120 in. (280 to 3050 mm)

No-Heat Length: 1 in. (25 mm) min.,

12 in. (305 mm) max.

Voltages: Up to 240VAC

Phase: 1-phase parallel or 3-phase wye

Resistance Coils: 1 or 3

Terminations: Flexible lead wires, quick connect

(spade), screw lug (plate) and threaded stud

Seal Material: Lavacone, rated to 221°F (105°C)

Single-End Configuration: Slotted

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.

Grieve Walk-In Ovens for Industrial Applications

Grieve Ovens, in business for over 50 years, is in the business of manufacturing the best industrial ovens in the USA.  Build in Illinois and completed tested, the Grieve oven will meet the test of time for your application for years to come.

Ovens and furnaces for which there simply are no equals...Grieve.

Walk In Ovens are used for paint baking, drying, preheating, annealing or any other heat processing of large or numerous parts at temperatures to 750°F. Oven size conveniently accommodates materials handling equipment. Choice of either combination or full horizontal air flow in either rear or top mounted heat chamber configurations. Designed and constructed for long, hard, continuous use.

• Every oven fully assembled and individually factory tested 

STANDARD FEATURES

Combination Air Flow

Heated air is provided from full coverage supply duct work at each side of the work space and sweeps upward through the load to a return duct at the top of the work space. Used in most shelf truck loading applications where sufficient shelf area is left open to allow vertical air movement upward through the loaded truck. Ideal for large parts placed directly on oven floor or loaded on a flat bed truck. 

Horizontal Air Flow

Heated air is blown horizontally across the work space between full coverage duct work. For shelf truck loading applications with densely loaded shelves, solid bottom trays, or flat sheets where heated air can only pass sideways above and below each level. Also used on oven floor or loaded on a flat bed truck. 

• Electric Models Each features completely wired, side access UL listed control panel enclosing terminals for incoming power, temperature controllers, push buttons and pilot lights. Motor starter and heating element contactors electrically interlocked to shut off heaters if power to blower is interrupted and to permit operation of blower without heat for cooling. Incoloy sheathed tubular heating elements.

• Gas Models

— 1,000 BTU natural gas at 6" water column pressure: 1" NPT inlet to 350,000 BTU/HR; 1-1/4" NPT to 1,200,000 BTU/HR
