With 20 years experience, Hongtai Alloy is your trusted source for quality 220v industrial screw plug immersion heater with thermowell as one of the leading suppliers of various heaters in China. Providing you with the most competitive price, we welcome you to buy the heater from our factory.
Product Description
The 220V Industrial Screw Plug Immersion Heater With Thermowell is a highly efficient, direct-contact thermal solution engineered by Yancheng Hongtai Alloy Electric Apparatus Co., Ltd for heating liquids in tanks, vats, and pressurized vessels. Designed for seamless installation, this heater features a robust threaded hex head (screw plug) that mounts directly through a tank wall, immersing the tubular heating elements directly into the fluid for nearly 100% heat transfer efficiency.
The defining technological advantage of this specific model is its integrated thermowell-a dedicated, sealed central tube positioned alongside the heating elements. This allows operators to insert a temperature sensor, thermocouple, or thermostat probe deep into the fluid for highly accurate, real-time temperature monitoring without exposing the sensor to the fluid or requiring the tank to be drained during sensor replacement. Manufactured with premium stainless steel, imported NiCr 80/20 resistance wire, and compacted Magnesium Oxide (MgO), this heater provides reliable, long-lasting performance for water, thermal oils, and chemical solutions

Features
- Integrated Precision Thermowell: The built-in sensor tube allows for exact temperature control and prevents fluid degradation or overheating, while enabling sensor replacement without draining the tank.
- Maximized Heat Transfer: Direct immersion into the liquid medium ensures that nearly 100% of the generated electrical energy is transferred as heat, significantly reducing energy consumption.
- Rapid Installation & Maintenance: The heavy-duty threaded hex plug allows for quick, wrench-tightened installation and easy removal from tank walls or pipe fittings.
- Custom Watt Densities: Elements can be engineered with specific watt densities to prevent carbonization (coking) when heating viscous fluids like heavy lubricating oils, or optimized for rapid water heating.
- Corrosion-Resistant Durability: Constructed from high-grade stainless steel or Incoloy, offering superior resistance to chemical corrosion and scaling in harsh industrial fluids.
- Secure Electrical Connection: Features an organized terminal block designed to withstand industrial vibration and ensure a secure, arcing-free power connection.
Applications
- Industrial Water Heating: Used in hot water storage tanks, boiler equipment, and commercial wash systems.
- Oil & Lubricant Reservoirs: Providing gentle, low-watt-density heat for hydraulic oils, lubricating oils, and thermal transfer fluids to maintain flow viscosity.
- Parts Cleaning & Degreasing Baths: Supplying continuous, controlled heat to aqueous cleaning solutions and alkaline baths in automotive and aerospace manufacturing.
- Chemical Processing Tanks: Heating mild corrosive solutions, anti-freeze (glycol) mixtures, and process chemicals requiring strict thermal regulation.
- Food & Beverage Processing: Food-grade stainless steel models are used for heating CIP (Clean-In-Place) liquids, brewing water, and edible oils.
