Thermal oil heaters: design and functioning

Forced circulation (or "coil", “serpentine”) Thermal oil heaters are used for heat generation in thermal energy transfer systems operated by circulation of a high-temperature diathermic fluid (oil).
These indirect heat transfer systems have several advantages over direct heating:

  • Accuracy in temperature control.
  • Uniformity of heating by avoiding local overheating.
  • Maximum safety: separation between user machine and heat source.

In a Gavardo Caldaie Thermal oil heater, a pump provides the forced circulation of oil inside a variable-section coil (also called “serpentine”), heated by the flame and combustion fumes of a burner. Sensors monitor the flow and temperature of the oil to avoid overheating.

Advantages in the use of thermal oil

Thermal oils currently used by industry are characterized by:

  • Wide operating range (up to 280 - 300 °C).
  • Possibility of operating at atmospheric pressure, resulting in simplified installations.
  • Non-toxicity and non-corrosiveness.
  • High lubricity and protection of plants from rust.
  • Low freezing point (possibility of outdoor installation even in cold regions).

A Gavardo Caldaie heater provides further advantages:

  • Excellent value for money
  • Maximum efficiency, safety and reliability
  • Thousands of applications in operation, across multiple sectors
  • Ease of use thanks to simple and intuitive operation
  • Consolidated experience over 60 years
