What is the approximate maintenance cost per year?
With the high reliability components selected for the microwave system, the only consumable part is the filament within the magnetron, which is guaranteed for a period of one year after startup. This results in a maintenance cost of one dollar per operating hour. However, the magnetron may be returned to the magnetron manufacturer, rebuilt , recertified, and returned to service – several times throughout its life. The cost to rebuild the magnetron versus replacement cost of the magnetron is 50% of the new price.
