Your Core Systems, Always Powered.

At CoreUptime Power Systems, we deliver complete, end-to-end generator, ATS, controls, and fuel system services designed to keep critical facilities operating without interruption. Whether you manage a data center, industrial plant, hospital, telecom site, or commercial building, our team brings more than 43 years of combined experience in mechanical, electrical, and controls engineering to every project we support.

 

We don’t just perform maintenance — we engineer uptime.

 

Below is our full suite of services.

Our Services

1

Generator Preventive Maintenance (PM) & Inspections

A reliable generator is the backbone of any critical facility. Our PM programs exceed industry standards and are customized for your equipment, load profile, and operational environment.

Services Include:

  • Full mechanical & electrical inspection

  • Oil, coolant, and filter service

  • Block heater, battery, and charger checks

  • Fuel system evaluation

  • Hose, belt, & sensor inspection

  • Exhaust system inspection

  • Run testing & parameter verification

  • Load transfer simulation (if requested)

  • Detailed digital service report

​

Why It Matters:

Regular PM ensures long-term reliability, reduces failures, and extends equipment life — especially under data-center and industrial loads.

2

Generator Troubleshooting & Repair

When a generator fails, the risk to operations is immediate. We specialize in rapid-response troubleshooting for both mechanical and electrical failures.

Capabilities:

  • No-start and no-crank conditions

  • Fuel delivery issues

  • Cooling system problems

  • Charging system failures

  • Fault codes & shutdowns

  • Engine mechanical failures

  • Vibration issues

  • Alternator output problems

Our Approach:

We combine mechanical experience with advanced controls diagnostics to isolate root causes quickly and accurately.

3

Generator Controls Upgrades (Modernization)

Aging control systems are one of the leading causes of generator and ATS failures. We specialize in upgrading legacy controllers to modern, high-reliability platforms.

Brands & Platforms Supported:

  • Deep Sea Electronics (DSE)

  • ComAp

  • Woodward

  • Basler

  • Legacy OEM controllers (CAT, Cummins, Kohler, MTU, Onan)

Services Include:

  • Full panel replacement

  • Wiring harness modernization

  • I/O mapping & programming

  • Engine interface configuration

  • Alarm & shutdown logic

  • Remote monitoring integration

  • Documentation & customer training

Benefits:

  • Increased reliability

  • Improved diagnostics

  • Standardized parts availability

  • Longer equipment lifespan

Controls upgrades are one of our core technical specialties.

4

Automatic Transfer Switch (ATS) Service & Controls Upgrades

Your ATS is the brains of your emergency power system — and most failures originate here.

ATS Services Include:

  • Full operational testing

  • Transfer & retransfer timing analysis

  • Contact/arc inspection

  • Heater & solenoid checks

  • Sensor & harness inspection

  • Mechanical linkage tuning

  • Load transfer simulation

ATS Controls Upgrades:

  • Logic modernization

  • Replacement of obsolete controllers

  • Utility communication logic

  • Closed/open transition configuration

  • Load shed & retransfer control

  • SCADA integration readiness

We specialize in solving ATS issues others can’t diagnose.

5

Fuel Polishing & Fuel System Service

Your generator is only as reliable as the quality of its fuel.

With decades of experience in fuel system analysis and remediation, we provide complete solutions to restore and maintain fuel integrity.

Services Include:

  • Full fuel polishing

  • Water & sludge removal

  • Tank inspection (internal & external)

  • Filter replacement

  • Algae contamination treatment

  • Fuel quality testing & reporting

  • Recurring fuel maintenance programs

Why It Matters:

Fuel degradation is responsible for a large percentage of generator failures — especially in standby units.

6

Load Bank Testing

Load testing ensures your generator performs correctly under real operating conditions.

We Offer:

  • Resistive load bank testing

  • Annual and commissioning tests

  • 30–2000 kW test capacity (larger available by request)

  • Step-loading and full-load verification

  • Voltage, frequency, and stability analysis

  • Exhaust & cooling performance evaluation

  • Comprehensive report package

Load banks are essential for compliance, reliability, and early-stage failure detection.

7

Critical Facility Support (Data Centers, Hospitals, Industrial Sites)

We support facilities where uptime is not optional.

Specialized Capabilities:

  • Redundant generator plants

  • Paralleling switchgear troubleshooting

  • Closed transition programming

  • Utility coordination

  • Black start testing

  • Tier-level readiness maintenance

  • Critical system documentation reviews

  • Reliability engineering analysis

This is where our mechanical + controls hybrid expertise sets us apart.

8

Emergency Response Service

When your generator or ATS fails unexpectedly, our experienced technicians respond quickly.

We Handle:

  • Emergency troubleshooting

  • ATS stuck transfer failures

  • Generator won’t start/no output

  • Controller faults

  • Mechanical breakdowns

  • Fuel contamination

  • Overheating issues

We understand that downtime costs far more than a service call.

9

Consulting & Technical Advisory Services

With over 43 combined years of industry experience, we offer specialized consulting services for organizations that require expert guidance.

Consulting Services Include:

  • System reliability assessments

  • Backup power infrastructure design review

  • PM program auditing & optimization
