Sugimat has designed, manufactured and installed oil and gas thermal oil heater for more than 40 years. With references in more than 28 countries, Sugimat is an international reference in hot oil heaters and uses first class oil and gas burners.

Quality and guarantee

The burner boilers manufactured by Sugimat meet the strictest quality standards, vertically integrated with the manufacturing in our workshops in Valencia.

In Sugimat, we are so sure of the quality of our boilers that we offer a 10-year guarantee on the pressure bodies manufactured for oil and gas fired thermal oil boilers.


Oil and gas thermal fluid boilers consist of two concentric coils inside of which combustion takes place and where energy is exchanged in the form of heat by means of radiation and convection.

Oil and gas thermal fluid heaters are designed for optimum efficiency and can be adapted to the requirements, and can include different features:

  • Vertical or horizontal execution.
  • Kit for efficiencies over 90% with dissociated burner and economizer.
  • System for low NOx.
  • Design for ATEX / IECEx zones.
  • Thermal oil economizers.
  • Application of API standard.


Thermal oil burner boilers can be operated with the following fuels:

  • Natural Gas
  • Synthetic gas
  • Light oil
  • Heavy Oil

In addition, they can work with different thermal fluids such as:

  • Diathermic oil
  • Synthetic oil
  • Medicinal oil
  • Biphenyl
