Gas/Oil Fired Thermal Oil Boiler is also called thermic fluid heater or hot oil boiler, which is an safe and energy saving boiler with working characteristics of low working pressure (0.8 MPa) and high temperature (330℃). This thermic fluid heater uses gas or oil as fuel, thermic oil as medium, hot oil circulation pump to make the medium to forced circulation, deliver the heat to heating need equipments and then go back to the heating furnace.It can obtain a high operating temperature at low pressure and can do high-precision control on the medium. TaiGuo Boiler has a mature R&D and design team, could customize the boilers based on customers’ requirement.


Coil Type Structure: Multi-loop coil design ensures uniform heating and prevents oil degradation.
3-Pass Design: Three-pass flue gas structure maximizes heat absorption and thermal efficiency.
Forced Circulation: High-velocity pump ensures rapid, stable, and continuous heat transmission.
Low-Pressure & High-Temp: Delivers up to 330°C heating at a safe, low working pressure of 0.8 MPa.
Automatic Control: Smart instrumentation enables high-precision temperature control and safe operation.

Bitumen, Asphalt & Building Materials: Used for bitumen heating, asphalt melting and dissolution, storage tank heating, concrete heating tanks, and asphalt mixing plants. It also delivers stable heat for gypsum board production, waterproof material manufacturing, and felt production.
Lubricating Oil & Petroleum Refinery: Applied in lubricating oil production and blending, crude oil refining, waste oil recycling/refining, grease manufacturing, and petroleum distillation processes.
Chemical Industry: Delivers precise high-temperature heat for polymerization and condensation reactions, esterification, distillation, rectification, concentration, evaporation, fusion, and resin/plastic manufacturing.
Textile Printing & Dyeing Industry: Powers stenter machines, heat setting machines, textile printing, ageing processes, and industrial drying rooms or dyeing jigs requiring stable, continuous thermal energy.
Timber & Wood Processing: Provides constant temperature heating for plywood and timber factories, hot presses, wood drying kilns, and the forming and processing lines of beaver boards, shaving boards (particleboards), and laminated sheets.
Plastic & Rubber Industry: Provides uniform, high-precision temperature control for industrial processes including hot pressing, calendering, extrusion, vulcanization, and artificial leather processing.
