About our Cummins service
Cummins is a major North American manufacturer with very large installed base in Mexican standby + emergency generation segment 0.5-3 MVA. Cummins generator sets typically combine Cummins diesel engine + Stamford generator-end (Cummins Generator Technologies owns Stamford brand). TEMISA Power Gen services the GENERATOR side of Cummins gensets (synchronous machine, AVR, brushless excitation, switchgear) under IEC 60034 and the EASA AR100 standard, with IEEE 56 as reference guide. For diesel engine service, we recommend coordinating with Cummins authorized dealer.

Frequently asked questions
Do you service both Cummins diesel engine and generator-end?
We focus on the GENERATOR-END (Stamford synchronous machine + AVR + brushless excitation + switchgear). For the Cummins diesel engine, we recommend coordinating with Cummins authorized dealer (Bramont, Tractomex, or others depending on region). We integrate our generator-side service schedule with diesel engine maintenance to enable unified shutdown coordination + cost optimization.
How does TEMISA Power Gen service Cummins equipment?
TEMISA Power Gen is an independent multi-brand service shop; the manufacturer's name identifies the equipment serviced.
What Cummins generator capacities do you typically service?
Our service range is 1 to 365 MVA. Most Mexican Cummins gensets are in the 0.5-3 MVA standby / emergency segment; units of 1 MVA and above fall within it. Common diesel engine + generator-end pairings: Cummins QSK60 + Stamford HCI634F (2 MVA), QSV81 + HCI744 (2.5 MVA), QSK95 + HCI834 (3 MVA), QST30 + PI series (1-1.5 MVA). All capacities serviced under same generator-end service approach. For larger Cummins gensets > 3 MVA in industrial cogeneration, scope expands to include process steam interface + heat recovery considerations.
Can you handle NFPA 110 Level 1 commissioning for hospital Cummins gensets?
Yes. NFPA 110 Level 1 commissioning for hospital emergency Cummins gensets requires: insulation Megger 5 kV IEEE 43, AC hipot at the voltage defined in the agreed test protocol, 100% load testing 2+ hours, cold-start < 10 seconds, sustained 8-hour operation under continuous load documented, switchover testing manual + automatic, NFPA 110 documentation package retention. Typical service: 2-3 days field. Annual recurring testing for Level 1 hospital compliance.
