Pneumatic vs. Electric Actuators

TOTAL COST OF OWNERSHIP (TCO) = INITIAL PURCHASE COST + (YEARS OF SERVICE x YEARLY COSTS)

YEARLY COSTS =

ELECTRICITY

+ REPLACEMENT
+ MAINTENANCE
+ PRODUCT SCRAP
+ LOST PRODUCTION
(DUE TO CHANGE OVER AND CYCLE TIMES)

 

The efficiency differences between an electric and pneumatic system can result in significantly different electric utility costs over the lifetime of the device.
