We have 50+ years of experience as a manufacturer of custom-designed heat exchangers and industrial heaters. Armstrong Engineering Associates produce radiant heaters, sheathed-element-type electric heaters, Electrofin finned element heaters and impedance heaters (direct electric heaters).
A heating element is a material or device that directly converts electrical energy into heat or thermal energy through a principle known as Joule heating. Joule heating is the phenomenon where a conductor generates heat due to the flow of electric current...
A cartridge heater is a cylindrical tubular heating device that provides concise and precise heating for various forms of materials, machinery, and equipment. Unlike an immersion heater, a cartridge heater is inserted into a hole in the item to be heated to furnish internal radiant heat...
Ceramic heaters are electric heaters that utilize a positive temperature coefficient (PTC) ceramic heating element and generate heat through the principle of resistive heating. Ceramic materials possess sufficient electrical resistance and...
Electric heating is produced by using a known resistance in an electric circuit. This placed resistance has very few free electrons in it so it does not conduct electric current easily through it. When there is resistance in...
An immersion heater is a fast, economical, and efficient method for heating liquids in tanks, vats, or equipment. Known as bayonet heaters, they have heating elements that can be directly inserted into a container of water, oil, or other material in order to heat the entire contents...
Infrared heating is a heating method used to warm surrounding bodies by infrared radiation. Thermal energy is transferred directly to a body with a lower temperature through electromagnetic waves in the infrared region...
