Custom Foil Heaters

Foil heaters can be fabricated to any shape and can be designed to vary the watt density so that the heat is delivered to precise locations. Foil heaters generally use low temperature coefficient foils; however, higher temperature coefficient can be used to provide current limiting. Heaters can be designed to be non-magnetic and/or non-inductive.

Foil heaters provide uniform heat distribution due to their low profile and intimate contact with the surface. This also contributes to faster heating and more reliable heater performance.
