Analysis of lubricating oil and hydraulic oils not only gives the condition of the oil but also gives a fast and accurate picture of what is happening inside the machinery like power generators, gearboxes, compressors, hydraulic systems and other critical machines. Lubricants have to work under demanding conditions, exposed to constant high pressures, temperatures and other harmful factors, including water contamination, corrosion, glycol ingress, soot formation, raw fuel, and air ingested particles. Effective monitoring of lube oil allows maintenance to be scheduled efficiently, minimising the risk of damage to expensive plants and avoiding unscheduled downtime and maintenance.
