Manufacturing & plants
Process loads, controls and life safety circuits across the Elgin, Huntley, Carpentersville and Rockford industrial parks.
Industrial generator service
Industrial generator service up to 1 MW
We service and install standby generators up to 1 megawatt, any brand, across Northern Illinois. Diesel and natural gas, single units and multiunit sites, with 24/7 emergency response.
Capability
Up to 1 MW. That number is our credential.
JRC services, tests, repairs and installs standby generators up to 1 megawatt (1,000 kW), diesel and natural gas, single units and multiunit sites.
Plant engineers and facility managers call us for the same reasons: a unit that's out of warranty with no servicing dealer, a load bank test nobody has run, a controller alarm the last vendor couldn't clear, or a site with three different brands that should be on one schedule.

Where industrial units run
Manufacturing, food, cold storage and critical sites
Food & cold storage
Spoilage math makes the case. We keep the units that protect inventory tested and ready.
Data & telecom edges
Small colo, edge, office and security buildings, plus temporary construction power around larger campuses.
Testing
Most industrial units never see real load between tests
Wet stacking, carbon buildup and unproven capacity show up the day utility power drops. A resistive load bank test proves the unit can carry its rating.
| Interval | What the standard calls for |
|---|---|
| Weekly | Visual inspection of the emergency power supply system (EPSS) |
| Monthly | Run at least 30 minutes at ≥30% of nameplate kW, or at the manufacturer's minimum exhaust temperature. Exercise the transfer switch. |
| Annual | If monthly runs never reach 30% load or exhaust temperature, a supplemental load bank test: 30 min at ≥50%, then 60 min at ≥75%. |
| Every 36 months | Four hour run at ≥30% of nameplate or required exhaust temperature (Level 1 systems). |
| Ongoing | Fuel quality: water, sediment and microbial growth in tanks, lines, pumps and filters. Annual diesel fuel quality testing. |

Common questions
Can't find your question? Call 847-951-3678 and talk to a technician.
What is the largest generator JRC services?
Up to 1 MW (1,000 kW). That covers most standby units at plants, cold storage, senior living, municipal and commercial buildings in our area.
Do you service diesel generators?
Yes, diesel, natural gas and LP. For diesel units we also sample fuel annually and arrange polishing when water, sediment or microbial growth shows up.
Can you install a new industrial generator?
Yes. As a Generac industrial dealer we supply and install units up to 1 MW, and we can quote replacements for aging units of any brand.
