2. What is a Thermal Oil Boiler: System Overview & Key Terminology

A thermal oil boiler is a closed-loop heat transfer system utilizing organic heat transfer fluids (thermal oils) to supply consistent high temperatures up to 350°C at low system pressures. Unlike water-steam boilers, thermal oil system solutions operate with reduced risk of scaling and corrosion.
Boiler thermal oil heaters are essential for:

Indirect process heating in chemical & food industries
Heavy oil extraction & pipeline heating
Textile dyeing & finishing lines
Biomass, asphalt, and bitumen plants

System components typically include: a fired heat carrier heater, circulation pumps, expansion/compensation tanks, and safety/auxiliary controls.
