Coolly Save Costs and Reduce Oil Consumption with Lubricants: An Example from the Brewing Industry

The refrigeration industry is undergoing a transformation. Global legislation is limiting the use of refrigerants with a high level of Ozone Depletion Potential (ODP) or Global Warming Potential (GWP).

As a result, to help reduce the impact on the environment, businesses are increasingly adopting natural refrigerants – such as ammonia (NH3), carbon dioxide (CO2) and hydrocarbons – with much lower GWP than the previous generation of refrigerants like hydrofluorocarbons.

However, switching to natural alternatives presents a number of new challenges to operators and OEMs – not least when it comes to lubrication. One such challenge was in Turkey.

Izmir-based brewer Türk Tuborg, one of the biggest breweries in Turkey, was experiencing heightened operating temperatures in all 11 of its GEA Grasso and Sabroe refrigeration compressors. This contributed to elevated oil consumption.

Türk Tuborg thus asked local ExxonMobil distributor, Makyağsan Engineering Services, for assistance in selecting a lubricant that would help overcome these problems.

Makyağsan, in partnership with ExxonMobil engineers, recommended a switch to Mobil Gargoyle Arctic SHC NH 68, a synthetic lubricant specifically developed for use in both screw and reciprocating refrigeration compressors using ammonia as a refrigerant. The advanced oil offers long operating life compared with mineral lubricants, excellent low temperature fluidity and good solvency for reduced deposit build-up.

Switching to ExxonMobil’s latest high performance synthetic refrigeration oil, Mobil Gargoyle Arctic SHC NH 68, helped Türk Tuborg:

  • Save €20,300 in a year

  • Significantly reduce the oil consumption of its refrigeration compressors by 73%

  • Reduce compressor operating temperatures by 80C, which lowered energy use

  • Extended drain intervals due to its enhanced operating life, which helped reduce waste oil disposal
