With predictive maintenance,the technician walks around the chiller and looks for anything unusual.
He should be looking at the condition of the:·
Loose insulation is a major cause of evaporator shells leaking. Water accumulates under the insulation. The water sits there, having no chance to evaporate. This causes rusting of the shell from the outside in. If left unattended the shell will eventually leak. The repair can be costly depending on the severity of the leaks. At Owens Companies, we've had to repair small patches and coat entire evaporator shells.During a recent inspection, one of our service technicians noticed cracks in welds that held the stator housing to the motor housing. These cracks were taken care of under a scheduled and controlled repair.Predictive maintenance services are procedures that are meant to avoid more costly repairs. Repair time can be reduced through the information gained by these various predictive maintenance analysis procedures.Parts are secured and personnel scheduled prior to the repair and a plan for the repair process is developed in advance.
