Immersion Heaters – Screw Plug Industrial Immersion Heaters
Immersion heaters are one of the most efficient technologies for industrial liquid heating. By transferring heat directly into the liquid, industrial immersion heaters provide fast heating, high energy efficiency, and precise temperature control in tanks and process systems.
At Dirac Industries, we supply high-performance screw plug immersion heaters designed for demanding industrial environments. Our electric immersion heaters can heat water, water with additives, glycol mixtures, oils, and chemical solutions.
Our range of industrial immersion heaters is categorized according to three main criteria:
- The type of liquid heated by the immersion heaters
- The shape and configuration of the immersion heater
- Whether the immersion heaters are ATEX approved according to the European ATEX114 directive
What Are Immersion Heaters?
Immersion heaters are electric heating elements that are installed directly inside a liquid. Because the heating elements are immersed in the fluid, electric immersion heaters can transfer heat efficiently through direct thermal conduction.
Compared with external heating systems such as heat exchangers or steam heating, industrial immersion heaters offer important advantages:
- Efficient direct heat transfer
- Fast liquid heating performance
- Compact installation inside tanks
- Easy integration in industrial process systems
For these reasons, tank immersion heaters are widely used in industrial manufacturing and process heating installations.
Screw Plug Immersion Heaters
Screw plug immersion heaters are one of the most common types of industrial immersion heaters. In this configuration, heating elements are mounted inside a threaded plug that can be installed directly into a tank wall or pipeline connection.
Once installed, the immersion heaters are fully submerged in the liquid, allowing efficient and uniform heating. Screw plug immersion heaters provide reliable heating performance while maintaining a compact design.
These electric immersion heaters are easy to install, easy to maintain, and suitable for both new industrial systems and existing installations.
Applications of Industrial Immersion Heaters
Industrial immersion heaters are used in many industries where controlled liquid heating is required. The versatility of electric immersion heaters allows them to heat a wide variety of industrial liquids.
Immersion Heater for Water
An immersion heater for water is commonly used in industrial systems for process water heating, cleaning systems, and industrial washing installations.
Glycol Immersion Heater
A glycol immersion heater is used in heating or cooling circuits where glycol-water mixtures act as heat transfer fluids. These systems are widely used in HVAC and industrial heat transfer applications.
Oil Immersion Heater
An oil immersion heater is used to heat lubricating oils, hydraulic oils, and fuel oils. Heating oil improves viscosity and ensures reliable flow in industrial equipment.
Chemical Immersion Heaters
Chemical immersion heaters are designed to heat aggressive or corrosive liquids used in industrial chemical processes. Special sheath materials may be required to ensure compatibility with the chemical solution.
ATEX Immersion Heaters
Certain industrial environments contain flammable gases, vapors, or dust that can create explosive atmospheres. In these situations, specialized ATEX immersion heaters must be used.
ATEX immersion heaters comply with the European ATEX114 directive and are designed to operate safely in hazardous environments.
- Explosion-safe immersion heater construction
- Certified surface temperature limits
- Protected electrical terminal enclosures
- Compliance with European industrial safety standards
ATEX immersion heaters are commonly used in chemical plants, petrochemical facilities, and oil and gas installations.
