Frequently Asked Questions (FAQ) about Vertical Three-Pass Oil & Gas Fired Thermic Fluid Heater
A three-pass design forces the hot combustion gases to travel through the heater three times before exiting. This maximizes the heat absorbed by the thermal oil, resulting in much higher fuel efficiency and lower exhaust temperatures.
The THERMPAC is designed for multi-fuel flexibility. Depending on the burner installed, you can use Heavy Oil (FO), Light Diesel Oil (LDO), Diesel, Natural Gas, or LPG. This allows you to choose the most cost-effective fuel available.
Thermic fluid heaters can reach 300°C at very low pressures (often below 2-3 Kg/cm²), whereas a steam boiler would require extremely high pressure (over 85 Kg/cm²) to reach that same temperature. This makes thermic fluid systems safer and cheaper to maintain.
The vertical layout is ideal for factories with limited floor space. It also provides better thermal circulation for the oil and simplifies the burner maintenance, as the burner is easily accessible.
The system includes several safety interlocks, such as low oil flow switches, high-temperature cut-offs, flame failure sensors (for gas/oil), and pressure relief valves, ensuring the heater operates safely 24/7.
