APPLICATIONS
The AHP series in-line air heaters are used to heat clean, dry air or gas for baking, drying, laminating, metal working, packaging, plastic welding, preheating, sealing, soldering, shrink fitting and synthetic fabric sewing. AHP series air process heaters provide hot air and gas up to 1000°F (540°C) with infinite control by varying the voltage and/or the air flow. Closed loop control can also be achieved with temperature controllers (section P) and "T" fittings to mount thermocouples.
*These air heaters can be operated on either 120 or 240 Volts. Specifications are shown for operation on both 120 and 240 Volts.
†Indicates Watts per inch of heated length. Use the table above to determine minimum required flow rates. The Watts per inch of heated length
can be changed by reducing the operating voltage or by ordering a custom made heater.
