VULCAN

VULCAN is a brand of industrial electric heating elements and process thermostats, widely specified for applications requiring controlled heat in manufacturing, processing, and maintenance environments. The product line includes cartridge heaters, immersion heaters, strip heaters, finned tubular elements, and direct-insertion thermostats, all designed for integration into OEM equipment or replacement in existing systems. VULCAN heaters are available in a range of wattages (200 W to 5,000 W), voltages (120V and 240V AC), and watt densities (21 W/sq in to 57 W/sq in), with sheath materials including copper and steel. The cartridge heaters are swaged for compact installation, while screw-plug immersion heaters feature NPT fittings for tank or pipe mounting. Strip heaters come in rigid and finned configurations, with offset terminals and mounting dimensions from 22 3/4 in to 23 3/4 in overall length. Finned tubular elements offer installation depths of 7 in for confined spaces. The Cal-Stat process thermostats provide adjustable screw control with a temperature range of -100°F to 600°F and a differential of 1/2°F, suitable for direct-insertion applications. Accessories such as thermostat knobs are available for field replacement. 3G Electric stocks VULCAN products for global distribution, supporting plant engineers and maintenance managers who need reliable heating components for process control, freeze protection, or thermal processing. The brand is commonly used in industrial ovens, packaging machinery, plastic processing, and fluid heating systems. All VULCAN heaters and thermostats are built to standard industrial specifications, with no proprietary certifications claimed beyond standard electrical ratings. 3G Electric provides technical specifications and part-number cross-references to facilitate replacement and new installations.

Common Applications

  • Industrial ovens — VULCAN rigid strip heaters (e.g., OS1423-1500B) for uniform heat distribution in drying and curing ovens.
  • Plastic processing — VULCAN swaged cartridge heaters (e.g., TB6025B) for injection molding and extrusion barrel heating.
  • Fluid heating — VULCAN screw-plug immersion heaters (e.g., AUO250B) for heating water, oils, or chemicals in tanks.
  • Packaging machinery — VULCAN finned strip heaters (e.g., OSF1517-1000B) for heat sealing and shrink wrapping equipment.
  • Process temperature control — VULCAN Cal-Stat thermostats (e.g., 1E1C9) for regulating temperature in pipelines or vessels.
  • Air heating — VULCAN finned tubular elements (e.g., RE8-1000B) for forced-air heaters and duct systems.

Frequently asked questions

Common questions about VULCAN from 3G Electric.

What types of VULCAN cartridge heaters are available through 3G Electric?

3G Electric supplies VULCAN swaged cartridge heaters in diameters such as 3/8 in and 5/8 in, with lengths up to 5 in and lead lengths of 10 in. Wattages range from 200 W to 500 W, with voltages of 120V or 240V AC. Watt densities vary from 38 W/sq in to 57 W/sq in. These heaters are designed for insertion into drilled holes for direct contact heating in platens, dies, and molds.

What is the temperature control range of VULCAN Cal-Stat process thermostats?

VULCAN Cal-Stat direct-insertion process thermostats have an adjustable temperature control range of -100°F to 600°F, with a differential of 1/2°F. They feature an open-on-rise switch action and an adjustable screw control type. The thermostat is designed for coupling pipe thread mounting, making it suitable for process piping or tank applications.

Are VULCAN screw-plug immersion heaters available with different sheath materials?

Yes, VULCAN screw-plug immersion heaters are available with a copper sheath and steel screw plug material. For example, the AUO250B model has a copper sheath and steel plug, rated at 5,000 W, 240V AC, with a 2 in NPT fitting and a watt density of 23 W/sq in. The control range is 100°F to 550°F.

What are the mounting dimensions for VULCAN rigid strip heaters?

VULCAN rigid strip heaters, such as the OS1423-1500B, have an overall length of 23 3/4 in and a mounting dimension of 22 3/4 in. They are rated at 1,500 W and 240V, with a watt density of 21 W/sq in and offset terminals. These heaters are designed for surface mounting in ovens or ductwork.

Can VULCAN finned tubular heating elements be used in confined spaces?

Yes, VULCAN finned tubular heating elements, such as the RE8-1000B, have an overall length of 8 in and an installation depth of 7 in, making them suitable for confined spaces. They operate at 240V and 1,000 W, with fins to increase surface area for heat transfer in air or gas applications.

What accessories are available for VULCAN process thermostats?

3G Electric stocks VULCAN thermostat knobs, such as the N15/4000-9, which are compatible with models like the N15/3015-3. These knobs are replacement accessories for field adjustment of temperature setpoints on direct-insertion process thermostats.
