TURBONYCOIL 640

Description:
TURBONYCOIL 640 is a lubricating oil with a viscosity of 5 cSt at 100°C. Fortified with an original in-house selected anti-oxidant, it is tailor-made to address requirements regarding low coking propensity, high resistance to oxidation and thermal degradation and elastomer compatibility.
Applications:
   > Gas turbine engines in military and civil aircraft (including helicopters)
   > Accessories (APU, IDG, starter, air cycle machine) of civil aircraft
   > Stationary industrial gas turbines (aero-derivative)

TURBONYCOIL 640 is recommended for use in hot running engine designs where evidence of oil coking and/or oil degradation was noted.
Main benefits:
  >  Outstanding high thermal stability
   > Excellent non-coking performance
   > High resistance to oxidation and thermal degradation
   > Low foaming tendency
   > Superior lubricity
  >  High conductivity

TURBONYCOIL 640 has shown higher long-term experience (+25% running operation life) versus rival oils on Allison 501-KB7S series.
Approvals:
>SAE AS5780 HPC*
>MIL-PRF-23699 HTS
>NATO CODE O-154
