Thermal Oil Boilers – OH Model

Thermal Oil Boilers – OH Model

The OH series consists of thermal oil heaters built with concentric helical coils, featuring one or more passes and a three-pass smoke tube design.

The heated thermal oil can be used both as a direct heating fluid and as a heat transfer medium for the indirect production of steam, superheated water, etc. These generators can accommodate any market-available burner.

Available accessories: oil circulation pump, oil filling pump, expansion vessel, oil collection vessel, evaporator, three-way control valve…

Boiler Body Structure

Our heaters feature a multi-stage tube bundle heating system, constructed from high-quality ASTM A 106 Gr.B steel, with flanged collectors and temperature sensor ports. The thick-walled cylindrical casing is reinforced and insulated with mineral rock wool, covered with polished aluminum sheet, ensuring high thermal efficiency and durability.
