Oil analysis is an essential tool in the proactive maintenance of vehicles and machines. The range of services from Alpha Systems Maintenance is based on the principle that machines that run on cleaner fuel, air and oil work longer and more efficiently, which can improve productivity and cut costs. A proactive maintenance method focuses on the causes of machine wear and defects. This strategy allows significant savings in terms of machine maintenance, because action can be taken before a symptom or defect in the machine becomes visible. This can also prolong the working life of mechanical machines. Unlike preventive and predictive maintenance, proactive maintenance can identify the most common and serious cause of defects: contamination. The first logical step in proactive maintenance therefore consists of the implementation of a strict contamination reduction programme for lubricating fluids, hydraulic fluids, gear oils and transmission fluids.
