Thermal Oil Heaters

Precision High-Temperature Indirect Heating

Boilertronix supplies specialised diathermic oil heaters, the ideal solution for industrial processes requiring high, stable, and uniform temperatures at low pressure. Our range offers exceptional performance and safety for your most demanding applications.

High Temperature, Low Pressure.

The safe and efficient alternative to high-pressure steam.

Thermal oil heaters provide significant advantages over traditional steam systems for high-temperature applications. By using a specialised thermal fluid instead of water, these systems can achieve precise temperatures up to 350°C at very low pressures. This enhances operational safety, reduces system complexity, and completely eliminates issues like corrosion, scale, and the need for water treatment.

Frequently Asked Questions​

The primary advantage is the ability to reach very high temperatures (300°C+) at very low pressures, which is significantly safer than a high-pressure steam system. It also eliminates corrosion, scale, and the need for water treatment, resulting in lower maintenance costs.

They are widely used in manufacturing, chemical processing, textiles, food processing, and any industrial application that requires precise, stable, and high-temperature indirect heat.

Maintenance is generally low compared to steam boilers. It typically involves regular checks of the burner, pumps, and safety controls, as well as periodic testing of the thermal fluid to ensure its quality and longevity.
