Mobil SHC Polyrex Produces €40,000 Cost Savings for German Mill


After switching to Mobil SHC Polyrex 462, for use in the rotary valves of their vacuum evaporators, a German Sugar Mill has benefitted from savings of €40,000 over the period of just 1 year.

Due to very high operating temperatures, up to 160 degrees Celsius, the plates, drums and rotors of the valves had short working life spans caused by high levels of wear. To combat this, ExxonMobil suggested using an NSF certified, synthetic grease, Mobil SHC Polyrex 462. This ensured the Mill was meeting all legal and safety requirements for food production lubrication.

The Mobil SHC Polyrex Series of synthetic greases are based on advanced Polyurea thickener technology which offers a combination of excellent water resistance, high temperature performance and balanced wear performance. Using a unique combination of synthetic oils, ExxonMobil researchers found they could achieve excellent high temperature performance to provide lubrication up to 170°C. These synthetic oils, combined with a Polyurea thickener and additives means Mobil SHC Polyrex greases have excellent load carrying capabilities and rust protection and can resist oxidation and loss of structural stability. Subsequently, re-lubrication intervals become few and far between whilst equipment protection levels are maintained. Mobil SHC Polyrex also has excellent corrosion protection and is highly resistant to water providing added equipment protection in wet, humid environments and applications where water wash downs are frequent.

Since moving to the high temperature, synthetic Polyurea grease, the sugar company’s overall grease usage has reduced. In addition, the life span of machine parts such as plates, drums and rotors has increased to around 6 years. This equates to a cost saving of €40,000!
