Nitrogen Blankets

Maintaining the Life of Your Thermal Fluid with Nitrogen Blankets

  • Both mineral and synthetic thermal fluids will oxidise when exposed to air temperatures in excess of 70ºC.
  • Nitrogen blankets protect thermal fluid from oxidation and reduce fire hazards.
  • Nitrogen Blankets Extend Fluid Life and Make a Safer System

Thermal Fluid and Oxidation

Oxidation leads to tar-like deposits in the oil which can plug strainers, pipes and heat exchangers, as well as the coil internals of thermal fluid heaters.

Oxidised products also increase the acidity of the oil. This can lead to corrosion, in particular in the expansion and drain tanks, in the overflow pipe and other parts of the system.

The typical starting point for oxidation of thermal fluid is in the expansion tank that is vented to atmosphere.
Large thermal fluid systems and heating and cooling systems need nitrogen blankets as do thermal fluids operating above their boiling points.

  • Extend thermal fluid life by eliminating the opportunity for oxidation
  • Nitrogen blankets secure your investment of the thermal fluid
  • Fire hazards are significantly reduced with Nitrogen Blankets
  • Automatic safe operational system used

Health and safety is paramount in business, not only in the sense of legal requirements to protect your people but also to protect your investment.

Nitrogen Blankets are available to retro fit most existing thermal fluid systems
