Screw Plug Heater

The Screw Plug Heater is a compact immersion electric heating device, specially designed for direct heating of liquid, gas or semi-solid media. It is directly installed in the threaded holes of containers or pipes through threaded interfaces and is widely used in industrial, civil and special fields. The threaded heater adopts high-quality heating elements and corrosion-resistant materials, which can provide efficient and uniform heating effects, and is suitable for small containers or scenarios that require precise temperature control. The product, with its features of easy installation, high thermal efficiency and strong reliability, has become an ideal choice for a variety of heating applications.

Features

1. Threaded installation design: Standard NPT or BSP threads (1/2" to 3") are adopted, which are convenient for direct screwing into the threaded interfaces of containers or pipes, and the installation is simple.

2. High-performance heating element: Built-in nickel-chromium alloy heating wire, filled with high-purity magnesium oxide, ensuring efficient heat conduction and electrical insulation.

3. Diverse materials: The sheath material can be selected from stainless steel (SUS304/SUS316), copper or Incoloy, adapting to different media and environments.

4. Temperature control and safety devices: Supports built-in thermostats, thermocouples or RTD sensors, and is equipped with over-temperature protection and anti-dry burning functions.

5. Compact structure: Suitable for small containers or space-constrained scenarios, with single or multiple heating tubes designed to meet different power requirements.

6. Protection grade: Multiple electrical enclosure options such as NEMA 1 (universal), NEMA 4 (waterproof), and NEMA 7 (explosion-proof) are provided to adapt to harsh environments.

Advantages

1. Easy installation: The threaded design does not require complex fixing devices, making it easy to install and disassemble, and reducing maintenance costs.

2. High efficiency and energy saving: With a thermal efficiency of over 95%, it heats up rapidly and reduces energy waste.

3. Precise temperature control: When combined with a temperature control device, it can achieve a temperature control accuracy of ±1°C, making it suitable for high-precision applications.

4. Strong durability: Corrosion-resistant and high-temperature resistant materials extend service life and are suitable for harsh working conditions.

5. Flexible customization: Power, voltage, thread size, sheath material and immersion length can be customized according to requirements.

Application

1. Industrial heating

Liquid heating: It is used for heating water tanks, oil tanks, and chemical solution tanks, and is suitable for the chemical, petroleum, and food processing industries (such as hot water, hydraulic oil, and asphalt).

Gas heating: It is applied to the preheating or heat preservation of gases such as air, nitrogen, and CO2, and is commonly found in environmental protection equipment and industrial furnaces.

2. Civilian field:

Hot water supply: Suitable for household or commercial water heaters, dishwashers, and coffee machines, providing a fast and stable heat source.

Cleaning and disinfection: Used for high-temperature cleaning equipment, such as spray washing machines and steam generators, to ensure hygiene standards.

3. Food and Beverage Processing:

It is widely used in food processing plants and beverage production lines to heat edible oil, syrup and sauce, maintain the viscosity of the products or perform pasteurization.

Ensure that the containers for food are sterilized at high temperatures before canning to extend the shelf life of the food.

4. Special Applications:

Medical and pharmaceutical: It is used for equipment sterilization and process fluid heating, meeting strict hygiene and temperature control requirements.

Anti-freezing protection: It is used for anti-freezing of pipelines, water tanks or storage tanks in cold environments to ensure the normal operation of the system.
