Load Bank Testing: (Recommended Interval – Every 12 Months)
(Annual test is REQUIRED for Hospitals and other life support providers if a load of 30% of the generator set’s nameplate rating cannot be achieved during the required monthly test.)
Optional 2 or 4 hour testing.  Minimizes potential of issues related to moisture build-up, settling of particles in fuel and carbon deposits in engine.  This is not only a recommended test, but per JCAHO and Public Health regulations, is a requirement for facilities providing life support systems, i.e. hospitals and nursing homes.

Load Bank Testing on your generator system is suggested to be performed annually to ensure your system is ready for the largest loads. Load Bank Testing applies desired loads to your generator set to monitor the performance and tests the capabilities of your system. Performing this test ensures your system is setup to handle the load it was designed to achieve.

Trusted Power Systems offers Load Bank Testing on Generators units all the way up to 150kW currently for Single Phase and 3 Phase applications. Contact us for more information.

Coolant System Flush: (Recommended Interval – Every 24 Months)
Reduces sediment buildup which could cause corrosion in coolant piping and tanks.
 

Belts and Hoses Replacement: (Recommended Interval – Every 24 Months)
Replacement of belts and hoses reduces risk of failure which could cause further damage to engine.
 

Fuel Cleaning: (Recommended Interval – Every 24 Months)
Reconditions, stabilizes and decontaminates fuels. It efficiently removes water, sludge and sediments that naturally accumulate in tanks.
