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 + IEEE 56 + EASA AR100 standards. For diesel engine service, we recommend coordinating with Cummins authorized dealer.

Applications
Industries we serve on Cummins
Hospital NFPA 110 Level 1
Cummins generator sets 0.5-3 MVA serving as Level 1 emergency power for Mexican hospitals requiring 10-second startup + 8-hour operation under NFPA 110 + Joint Commission compliance.
Datacenter Tier III + Tier IV
Cummins backup gensets 1-3 MVA per N+1 redundancy for datacenter Tier III/IV facilities under Uptime Institute requirements.
Commercial + industrial standby
Cummins standby gensets for commercial buildings, manufacturing facilities, telecommunications infrastructure emergency backup under NEC + IEC 60364.
Mobile + temporary power
Cummins mobile generator units for emergency relief + temporary industrial power applications — typical 0.5-1.5 MVA capacity range.
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.
Are you authorized by Cummins?
No. TEMISA Power Gen is an INDEPENDENT multi-OEM workshop — not a Cummins authorized representative. The GENERATOR-END is typically Stamford (Cummins Generator Technologies) which we service under IEEE 56 + EASA AR100 standards equivalent to factory. For warranty and Cummins-specific parts, the customer continues to engage Cummins authorized dealer for those specific items.
What Cummins generator capacities do you typically service?
Most Mexican Cummins gensets are in 0.5-3 MVA standby / emergency segment. 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, Hipot AC IEEE 95, 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.
