Our Predictive Maintenance is a comprehensive program that consists mainly of Load Bank Testing, Infrared Thermal Inspection, Fuel Analysis, Oil Analysis and Coolant Analysis.

Once we have completed the examinations, we compile the data into an in-depth report and than determine what corrective actions are required to detect and avoid equipment deficiencies that could lead to unnecessary downtime or equipment failures.

We provide one of the most innovative and robust maintenance programs in our industry! One of our key services is our instant iPad reporting that generates accurate data and photographs collected during a visit to your facility. Our reports are immediately emailed to your facility mangers in an organized and legible report. We store all reports generated by our company and they can be accessed at anytime.

load-bank-nov23a2Load bank testing is one of the best methods to test your emergency power engine/generator system. We will test your system to check for complete & full operations with the following steps:

Take unit off line 

  • Turn unit off
  • Make connections
  • Do pretest inspection

Start Testing 

  • Apply 25% load, Record all numbers (Volts, AMP, HZ, Oil Pres, Water Temp, Air Temp ECT.)
  • Apply 50% load, record all numbers (Volts, AMP, HZ, Oil Pres, Water Temp, Air Temp ECT.)
  • Apply 80% Load, Record all numbers (Volts, AMP, HZ, Oil Pres, Water Temp, Air Temp ECT.)

Finish Testing

  • Cool down engine (Shut down Load banks, let engine run unloaded)
  • Disconnect wires
  • Complete reporting and make any suggestions in writing.
  • Paper work turned into building engineer


infrared thermal inspection serviceOur Infrared Thermal Inspection analyzes your emergency electrical, mechanical and machinery power equipment by measuring and viewing the different temperature patterns. The temperature levels help locate malfunctioning components or connections prior to a failure in a nonabrasive and nondestructive way. The camera and diagnostic equipment can examine pre and post repair conditions and control and detail an accurate data collection reporting.  We inspect the following:

  • Connections
  • Insulation
  • Lighting
  • Overloading
  • Wiring
  • Visual Inspection
  • Thermography
  • Switch resistance

Our Fuel, Oil & Coolant Analysis creates a comprehensive data that is collected from the fluid samples in your generator and detects for contamination or deterioration when your fluid levels do not meet industry standards. By conducting oil, coolant and fuel testing on an annual basis, you help prolong the longevity of your equipment and prevent equipment failures.

Below are details for each fluid test and their importance:

Our Fuel Analysis helps ensure that your power supply system will work when needed the most during a power outage, as 80% of emergency generator engine failures are fuel related. Our Fuel analysis helps determine if there is fuel deterioration, bacteria, fungus, rust, sludge or water accumulation on the bottom of the tank. We do the following inspection:

  • Particle Count
  • Karl Fischer Water
  • Bacteria

Our Oil Analysis is a quick way to analyze the health of the engine. When we conduct an oil analysis we look at the thickness of the oil, see if there are any abrasive solids present, levels of metals, additives and temperature. Each one of these gives us a great thorough insight of the condition of your engine and helps us determine what next steps we can take to protect the equipment functioning properly. We test for the following:

  • Insolubles test
  • Viscosity test
  • Flash Point test
  • Spectral exam

Our Coolant Analysis helps increase the life expectancy of your engine coolant and remove problems that would occur from being contaminated. By periodically getting your engine coolant analyzed you prevent any form of contamination being spread throughout your engine, transmission and hydraulic system. We do the following analysis:
  • ICP Spectroscopy
  • Karl Fischer Water
  • PH
  • Freeze Point

Predictive Maintenance FAQ

Why is a load bank testing important?

A Load bank test essentially mimics what would happen in the event of a power outage and places a heavy, sustained load on the generator. This test allows us to verify how the generator will react during a power outage.

What is the difference between a load bank test and a building load test?

A building load test (BL) is a simple test of the building’s load. It’s a transfer of the building power to the generator through the transfer switch. A load bank test (LB) is a carefully graphed test using a separate piece of equipment, either a load bank trailer or load bank suitcase. The load bank is hooked up to the generator-set using cables and graphed during applied loads. A load bank test either steps upwards with an applied nameplate % load or it runs continuously at a high % of the nameplate oftentimes used for the elimination of wet stacking of diesel fuel.

For Example:

Stepping 4 Hour Load Bank: 1 HR: 25%, 1 HR, 50%, 2 HRS 75-80%.

Continuous 4 Hour Load Bank: 4 HRS at 75% of the generator name plate.

How often should a load bank be performed?

It is advised that load bank testing be performed on your generator once a year if not every three years. If you cannot afford to lose power, it is recommended to perform a load bank test once a year. It is the only way to truly see how your generator will perform during a controlled environment. At the end of the load bank test you have an intricate report showing you in detail how well your generator set ran during certain percentages of the nameplate. If there was a voltage drop at a point, we will see it on the graph and can act to correct those problems. During the next emergency, you will have a generator-set that is ready to perform.

What is the purpose of taking fluid samples?

It provides important information on the workings / condition of internal components. By testing the fluid, you can be able to tell when an issue is present before it becomes a catastrophic failure.

How do you analyze the sample collected?

We have contracted through a 3rd party independent lab that specializes in fluid analysis.

Will I receive a report of the lab’s findings?

Yes, once we have collected and analyzed the results, we will forward you a copy of the results along with any recommendations that we feel should be acted upon.

What is the benefit of using thermal imagery in your field?

Thermal imagery allows our technician to be able to verify hot / cold spot on electrical and mechanical equipment. This would allow us to see potential problem areas prior to complete failure of the equipment.

Will I receive a report after the service?

Yes, after each service a fully customized report will be given of our findings recommended corrective actions (if any).
