An Australian coal miner operating CAT 994H loaders was continually experiencing a high frequency of component failures due to heavily contaminated oil. Compounding the problem, was all main hydraulic circuits which shared a common reservoir and hydraulic fluid, which meant component failures in one circuit produced contaminants that circulated throughout the entire system, causing  additional damage and accelerated wear on components that were otherwise in good condition.

Mag-Shield^®s performance was monitored for 5,180 hrs with no failures experienced during this period. In addition, over the course of normal operation, 110 grams of ferrous material was captured by Mag-Shield^®. Ensuring ferrous contaminants are captured during normal operation is key to improving oil cleanliness and component life which helps mitigate failures. This results in less disruption to mine site operations, improved availability and significant savings.
