Thermal Oil Boilers
ENEVA thermal oil heaters are high-efficiency heat generation systems designed for industrial processes requiring high temperatures at low operating pressures. They provide a safe and long-lasting alternative in applications where steam is not technically or economically suitable.
- Oil outlet temperature up to 350 °C
- High temperature advantage at low pressure
- Stable, corrosion-free, and homogeneous heat transfer
- Suitable for chemical, textile, food, and process industries
- Lower maintenance requirements and long service life
In ENEVA thermal oil heaters, heat is transferred to the thermal oil circulating within a closed loop system. After releasing heat to the process, the oil returns to the heater, creating a continuous cycle.
- Smooth and continuous flow with helical coil design
- Oil film temperature maintained within safe limits
- Optimized pressure drop for low pump energy consumption
- Efficient and safe operation
- Chemical and petrochemical plants
- Textile and finishing lines
- Food processes (frying, roasting, etc.)
- Packaging and plastic production
- Asphalt and bitumen plants
- Sludge drying and special process applications
