Because the air being heated passes directly over the resistance wire, maximum heat transfer efficiency is achieved. Bluewater Heater brand air heaters are used for heat staking, plastic welding, laminating, drying, heat sealing, and any other operation where air needs to be heated up 1000°F. OPTIONAL THREADED INLET AND OUTLET CONNECTIONS ARE AVAILABLE - PLEASE INQUIRE OTHER TYPES OF AIR HEATERS ARE AVAILABLE WITH MORE HEATING CAPACITY - PLEASE INQUIRE -
Watlow® duct heaters are constructed of sturdy 0.430 in. (11 mm) diameter WATROD™ heating elements mounted to a 1⁄4 in. (6 mm) thick steel flange. These air duct heaters are easily adapted to many non-pressurized air-heating systems. Duct heaters are easily installed in applications requiring a wide range of temperature versus air flow combinations. -
The Watlow Finbar heater combines a one inch single-ended Watlow FIREBAR® flat tubular heating element press-fitted together with aluminized steel fins. The steel fins effectively increase surface area to approximately 16 square inches for every linear inch of element length drastically improving heat transfer to the air. Improved heat transfer allows the Watlow Finbar heater to put more heating power in tighter spaces - like forced air ducts, dryers, ovens, and load bank resistors.
