ADVANTAGES

Total Hydransafe FR-NSG 38 is a fluid free of water which displays superior fire resistance properties (ISO Standard 12922). It has an excellent overall performance in hydraulic circuits and hydraulic governor systems of steam turbines according to OEM requirements :

  • Good lubrication performance and anti-wear properties.
  • Excellent oxidation stability.
  • Low volatility.
  • Prevention of foaming and very quick air release.
  • Good resistance to hydrolysis and very quick demulsibility.
  • Excellent shear stability.
  • Good filterability

SPECIAL INSTRUCTIONS

Total Hydransafe FR-NSG 38 is not miscible with conventional hydraulic mineral oils or with water-glycol fluids. However Total Hydransafe FR-NSG 38 can generally be mixed in any proportion with phosphate ester based fluids.

Certain precautions must be taken when using Total Hydransafe FR-NSG 38 especially in an equipment designed to be used with a mineral oil :

  • Seals and hoses : these fluids are not compatible with conventional elastomers. Use only fluorinated elatomers (Viton – Teflon).
  • Paints : Total Hydransafe FR-NSG 38 will cause normal paints to dissolve or swell. It is best to avoid using paints on tanks (special resins are available that are compatible with phosphate esters).

As a general rule we recommend that the user consult AFNOR E 48-640 on “How to use fire-resistant fluids”.
