General Info

downloadDBK-USA specializes in manufacturing PTC (Positive Temperature Coefficient) heating elements. These heaters are made from a combination of two semiconductor materials–Titanium and Barium.  The chemical composition is designed to cause the material’s surface temperature to rise as electrical current flows through it. During this initial phase of applying electricity, the resistive nature of the compound’s crystal structure rises exponentially, causing the current’s flow to eventually slow to a trickle.  With no electrical current flowing, there is no additional heat generated within the semiconductor’s surface. This chemical structure produces a self-regulating PTC heater.

The crystalline structure of each compound within the heater is engineered to start generating resistance and heat again when the surface temperature falls below a specific minimum temperature level. The PTC heating elements are designed to achieve and regulate operating temperatures in 10 degree intervals with a minimum of 40 deg C/104 deg F and a maximum of 220 deg C/428 deg F.
