Band Heaters

Band Heaters

A band heater is a heating device that clamps onto objects to provide external heat using radiant and conductive heating. The different mounting methods of band heaters makes it possible to secure them tightly and firmly such that they do not shift or loosen...

Cartridge Heater

Cartridge Heater

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

Ceramic Heaters

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 Heaters

Electric Heaters

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...

Heating Element

Heating Element

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...

Immersion Heaters

Immersion Heaters

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

Infrared Heating

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...

Radiant Heaters

Radiant Heaters

Radiant heaters are systems that generate heat internally and then radiate it to the nearby objects and people. The sun is a basic example of a radiant heater. When we feel warm on our bodies on a sunny day...

Types of Electric Heaters

Cartridge Heater Inserted into a Plastic Mixing Block

The idea of an electric heater seems to be out of place in modern society since most buildings have a sophisticated central heating system. That may be true, but electric heaters can be a helpful way of saving energy while...

Thermocouples

Thermocouple

A thermocouple is a transducer that converts thermal energy into electrical energy and is constructed by joining wires made from dissimilar metals to form a junction. Voltage is produced when the temperature at the junction changes...

Heating Elements

Heating Elements

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...

Infrared Heaters

Industrial Infrared Heater

Infrared heating is a method for heating materials that uses electromagnetic waves to transfer energy from the infrared source to the product without heating the air in between. The emitted infrared energy is between 0.7 microns (µ) and 6 µ...
