Various Shaped Oven Bake Heating Tubular Electric Heaters High Pressure Resistance
1) Resistance For Electric Oven are the most versatile and widely used source of electric heat for industrial, commercial and scientific applications. They can be designed in a wide range of electrical ratings, diameters, lengths, terminations, and sheath materials.
2) Also screw plug immersion heaters, flanged immersion heaters, circulation heaters, and high temperature process air heaters are available.
3) GME is available to assist with the design and development of special heaters for particular requirements.
4) Electric Tubular Heater is a tube-shaped, heavy-duty, industrial joule heating element (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Highly compacted they reach a surface watt density of up to 30 w/cm².
