anac gas

The in-depth diagnostics system for industrial gas engines TOTAL ANAC GAS is an in-depth diagnostics system for the follow-up of the behaviour and depletion of the lubricant and the mechanical wear of industrial gas engines. TOTAL ANAC GAS is recommended for:
• Follow-up of engines operating on natural gas, landfill gas, sewage gas or liquid manure gas.
• Determination of the optimal oil drain period.


Mechanical wear: Wear elements Iron, Lead, Copper, Tin, Chromium, Aluminium, Nickel (ppm)

Contamination of the lubricant: Silicon ( ppm), Water (%), Cooling Liquid (Na and B in ppm). Optional : chlorine concentration, provided by landfill gas

Characteristics of the lubricant: Viscosity ( mm2/s ) at 40° C and 100° C, Viscosity Index Base Number TBN (mg KOH/g) and Acid Number TAN (mg KOH/g) Initial pH (iPh) Infrared spectrometry: determination of oxidation (Abs/cm at 1710 cm-1), determination of nitration (Abs/cm at 1630 cm-1)

Optional: Additive elements Ca, Zn, P, Mg, Mo, Ba, V, Na, B, K, Ag


The diagnosis and comments are established with the support of the TOTAL ANAC database and individually verified by a TOTAL ANAC technician, specialised in industrial gas engine lubrication and technology.

The TOTAL ANAC GAS diagnosis applies the limits indicated by every individual gas engine OEM, for wear metals as well as for oil characteristics.

The TOTAL ANAC GAS expert takes into account the specific knowledge on the operating conditions of industrial gas engines and possible remarks by the user. More than 15 years experience in the follow-up of combustion engines running on every type of gas.

Personalised responses on questions by the users are provided.
