Water or steam are commonly used in heating systems as heat transfer medium.
But at high temperatures require correspondingly high working pressures.
A mineral thermal oil can be used at atmospheric pressure up to 300 ° C.
For comparison water or steam requires a pressure of 85 bar to obtain the same temperature.


With the use of thermo oil there will be no corrosion and sediments in the pipes and fittings of your system.
No expensive and complex water treatment necessary. No risk of freezing at low temperatures, therefore very suitable for combined heating-cooling systems.
GTS Thermo oil heating systems are generally build as closed systems. The Thermo oil in the expansion tank is blocked from the atmosphere by a Inert gas (Nitrogen). This increases the lifetime of the thermo oil extremely.


The advantages of a GTS Thermo oil plant summarized:

  • High temperatures, up to 300 ° C, at atmospheric pressure
  • No corrosion
  • No risk of damage by freezing
  • Low maintenance costs
  • High efficiency
  • Low investment costs
  • No water treatment necessary
  • Extremely long service life of the thermal oil
