Preventative Maintenance Options


UPS Power Protection Services


Elevated PM Frequency
Some of our customers prefer accelerated PM frequencies including monthly or quarterly Preventive Maintenance visits. All our Service Packages are customizable to meet the unique needs of our customers.

Predictive Analysis
Included in the Service Packages are two preventive maintenance visits per year during which any wear items are replaced and the equipment is extensively analyzed. We employ Field Engineers trained in predictive analysis skills allowing us to manage equipment performance, rather than waiting to react to failures and the inevitable subsequent downtime.

Depot Service Preventive Maintenance
For smaller power conditioning units either requiring periodic PM's or battery replacement, our Depot Service is a cost effective option. As part of any depot service activity, a thorough preventive maintenance procedure is followed along with any remedial service required.

Enhanced Battery Maintenance
Gruber Power recognizes Batteries are an integral part of any critical power application.

We are the only independent maintenance organization that manufactures a line of batteries specifically designed for critical power applications.

Optimal battery service life is realized through routine maintenance. As a battery ages, its capacity drops. Annual battery testing is recommended to measure the energy that a battery is able to store. A reading of 80% or less indicates that a battery should be replaced.

Gruber Power Service Packages include battery maintenance usually performed during preventative maintenance service visits. As a battery manufacturer, you can be assured of:

  • Freshest possible batteries
  • Ample supply of all types, sizes, styles
  • Lowest cost - We have removed all middlemen
