The 1-inch SUS304 flange provides a compact installation solution for oil tanks where available mounting space is limited.
The Φ6.6 mm Incoloy 840 tube provides good resistance to high-temperature oxidation and is suitable for tubular heating applications requiring durable heating elements.
Available in 150 W, 300 W, and 450 W at 230 V, allowing the heater to be selected according to tank size, oil volume, and required heating performance.
The terminal box provides a protected connection area for wiring and helps simplify installation compared with an exposed electrical connection.
The heating tubes transfer heat directly to the surrounding oil or liquid, providing a compact and efficient heating method without requiring an external heating chamber.
For OEM applications, dimensions, power, voltage, flange configuration, lead connection, and other construction details can be reviewed according to the customer's tank design and installation requirements.

This flange heater is mainly used for oil tank heating and liquid temperature maintenance.
Typical applications include:
For oil tank heating, a flange-mounted tubular heater offers a relatively simple structure compared with external heating methods. The compact 1-inch flange, Φ6.6 mm Incoloy 840 tube, 230 V power supply, and terminal box make this configuration suitable for small industrial oil tanks and equipment requiring direct immersion heating.
For custom projects, Jaye Heater can review the tank dimensions, oil type, required temperature, heating power, installation position, and available mounting space to determine a suitable heater configuration.
