PTC Technology


In today’s heating technology marketplace, there is a growing  demand for conductive polymer materials. Unlike traditional surface heaters with resistance wires that can break and cause heater failure, conductive polymer materials have a structural integrity and flexibility that makes it the most versatile surface heating product available.

STEP® Heating Element has all the properties and applications of existing conductive materials. In addition of being the most advanced in quality, usage and durability, the product has a superior and unique technology advantage – it is self-regulating. The heating elements of STEP® systems are based on nanotechnology. The nanomaterial modifies its behavior of condition when electrically charged. A function of the structural homogeneous blend with other materials makes the element naturally self-regulating and inherently safe.

STEP® Heating Elements use only the energy necessary to maintain an even temperature. They cannot overheat. When the ambient temperature increases, the morphology of the polymer structure changes and the particles separate reducing the points of contact between each other. As the electrical resistance increases less current can circulate and the emission of heat decreases.

STEP® Heating Element can be adapted to fit specific applications. The heat generated by the elements is obtained by altering either: a) the voltage; b) the width; c) the thickness; d) the distance between bus braids; e) the composition of the conductive compound.

STEP® Heating Element is covered by U.S. and international Patents and patents pending.

Low voltage

STEP® is the safest electric system on the market. The STEP® heating elements operate at an extra-low voltage (24 volts, AC or DC). Using safety extra-low voltage (SELV) is one of several means to protect against electrical shock. The safety of a SELV circuit is provided by the extra-low voltage (under 30 volts) and the risk of accidental contact with a higher voltage.

STEP® heating elements should not be grounded. The safety of a SELV circuit lacks a return path through a ground source so that an electric current cannot come in contact with a human body. Using direct current (DC) produces a static field, which does not induce electric currents in humans. STEP® has a low electric magnetic field.

STEP® heating elements are normally connected to a 24 volt transformer, and can also be powered by solar or wind sources.
