Preventive and Predictive Maintenance

Preventive maintenance has the primary objectives of prolonging equipment life, whereas predictive maintenance aims at foreseeing a failure or breakdown in advance, in ordre to avoid unplanned interruptions to production. Both of these measures help to keep equipment in good condition and achieve operating conditions as close to optimum as possible. By doing this, they also help reduce energy consumption.
