BSI – Boiler and Steam Installations
High-temperature heat transfer systems delivering stable, efficient heating without high pressure.
Thermal Oil Boilers
Thermal oil boilers, also known as thermal fluid heaters, are industrial heating systems designed to transfer heat using a specialised thermal oil instead of water or steam. The thermal fluid circulates through a heat exchange body where it absorbs energy generated through combustion of various fuel sources.
At Boiler and Steam Installations (BSI), our thermal oil boiler systems deliver high-temperature heat safely and efficiently while operating at low system pressures.
How Thermal Oil Boilers Work
Industrial thermal oil boilers consist of one or more coils through which the thermal oil circulates. Combustion gases pass around these coils, transferring heat directly to the thermal fluid.
Thermal oil circulates through coils designed for direct, efficient heat absorption.
Combustion gases pass around coils, transferring heat directly to the thermal fluid.
A pump moves heated oil to the process, maintaining stable flow and temperature.
After heat transfer, oil returns to be reheated—continuous, efficient operation.
This continuous closed-loop system ensures consistent temperature control and efficient operation throughout your process.
Applications
Thermal oil boilers are widely used where stable, high-temperature heat—up to approximately 400°C—is required without the high pressures associated with steam systems. Typical applications include:
Fuel Flexibility
BSI thermal oil boilers can be engineered to operate efficiently using a wide range of fuels:
This flexibility allows clients to select the most cost-effective and sustainable fuel option for their operation.
Advantages
Thermal oil systems offer key advantages over traditional steam systems:
