Positive Temperature Coefficient

What are PTC Heaters?

Safety and Efficiency of PTC Heaters

Electrical heaters for industrial applications are typically better and more rugged than those for commercial applications. Industrial applications typically require higher heat output, more durability, and longer lifespan and are often used in harsher environments than commercial applications.

What you need to know about PTC heaters

PTC ceramic heaters, how they are made and used.

PTC ceramic heaters are an electrical heating element that uses the PTC (positive temperature coefficient) effect to control their temperature. In a PTC ceramic heater, the resistance of the heating element increases as its temperature rises, which limits the amount of power that can flow through it and helps to prevent overheating.

3 Phase Electric Duct Heater

What are 3 Phase Electric Duct Heaters? 

A three-phase electrical circuit can supply three times the power as a single-phase circuit at the same voltage with only one additional wire.

Commercial and Industrial duct heaters utilize 3 phase electrical power to produce more output wattage per square inch than single-phase electric heaters. Higher voltages result in higher currents and more heat output. With limited cross-section area in heating ducts, higher 3-phase voltage connections are more efficient.

Low Voltage Flexible Silicone Rubber Heaters

An etched foil heater is built by etching foil tracks that conduct electricity laminated between layers of silicone rubber and nylon for strength and durability.  Etched foil as a resistive element is much thinner than wire resistive elements with better heat distribution across the heater's surface.
