An Oil/Gas Fired Thermic Fluid Heater is an advanced and efficient industrial heating system designed to provide indirect heat for process applications without the limitations of direct steam heating. Instead of water or steam, the system uses thermic fluid (heat transfer oil) as the heating medium, which allows operation at high temperatures (up to 300–350°C) at atmospheric pressure. This eliminates the need for high-pressure boilers, ensuring safety, reliability, and low maintenance costs.
These heaters are widely used in textile, chemical, pharmaceutical, food processing, rubber, plywood, and petrochemical industries, where precise temperature control, continuous heating, and energy efficiency are critical.
The oil/gas-fired burner ensures clean combustion and consistent heating, while the system is engineered with high thermal efficiency, minimal heat loss, and environment-friendly operation.
