Screw Plug Heater
Screw plug heaters are compact, high-efficiency immersion heaters designed for direct heating of liquids and gases in tanks, vessels, and pipelines. The heating elements are brazed or welded into a threaded plug, allowing easy installation into standard NPT or BSP threaded openings.
These heaters offer rapid heat-up, uniform temperature distribution, and minimal heat loss, making them ideal for applications ranging from water and oil heating to chemical processing. Available in a variety of sheath and plug materials, screw plug heaters can be configured for safe operation in hazardous or corrosive environments.
Advantages
- Compact & Efficient – Direct immersion ensures minimal heat lossI.
- Easy Replacement – Elements can be changed without draining the vessel.
- Versatile Material Options – Sheath and plug alloys for water, oils, and chemicals.
- Hazardous-Area Ready – Explosion-proof and flameproof designs available.
- Fast Heat-Up – High watt density for rapid thermal response.
- Durable & Low Maintenance – Long service life with robust construction.
Applications
- Water Heating – Process tanks, storage vessels, and cleaning baths.
- Oil Heating – Lubrication oil, hydraulic oil, and thermal fluids.
- Chemical Processing – Vessels, baths, and reactors.
- Steam Generation – Boilers and steam-producing systems.
- Grease & Solvent Heating – Industrial cleaning and processing systems.
Features
- Direct Immersion Design – Maximizes heat transfer efficiency.
- Replaceable Elements – Service without full system shutdown.
- Corrosion Resistance – Alloy options to match process fluid chemistry.
- Safety Options – Explosion-proof and flameproof variants available.
- Rapid Heat-Up – Uniform heating with high watt density.
- Long Service Life – Built for demanding industrial environments.
