Electrical Heaters


         
AMETEK Airtechnology Group has developed a range of heaters and fan heaters for aerospace applications with a wide range of heating outputs. Heaters and fan heaters can be supplied to suit all standard and special duct configurations.

For our fan heaters, we use fans (from our fan range) that provide a very low noise signature while providing the desired flow and pressure. Our Mixed-Flow fans are often used in our designs as these provide the best noise, flow and pressure characteristics while also providing the non-stall characteristic inherent in the mixed flow design. According to your requirements, fan heaters can be configured for 28 VDC (brushless), or single/three phase 400 Hz supply.

Our newest heaters feature a robust, lightweight design, complete with complex controls and sensors to ensure they maintain the required temperature. What’s more, their multi-layered, fail-safe technologies meet the most stringent safety requirements (typical of modern-day commercial airliners).

Heater elements can be supplied with 28 VDC, 270 VDC, and 115/200 VAC supplies. Power ratings range from 125 W up to 6 kW and are fully protected by thermal switches that can interface with onboard aircraft systems to isolate the heater in the event of a malfunction.

                     

  • Heater Rods +


    This type of heater uses a cartridge type “heater rod” which is inserted into an aluminium heat-sink.

  • Silicone Mat +


    High-resistance wire is sandwiched between layers of glass reinforced silicone rubber. The mats are bonded on to aluminium tubes which are arranged in a “nested” configuration. This arrangement provides a very large area for heat transfer and a low pressure drop while minimizing the heater surface temperature.

  • Polyimide Etched +


    An etched foil heater track is sandwiched between layers of polyimide which is bonded to a flat plate or surface form. The plates are typically stacked together to form a heater core. Like silicone mat, this arrangement provides a very large area for heat transfer and a low pressure drop, while minimizing the heater surface temperature.
