The best way to avoid an expensive breakdown is to get your genset serviced from trained professionals.
If the power is not there even for an hour, you lose money in lost productivity or leave people stranded. Diesel generators are your best alternative power source — provided they actually start when you need them.
At OVN we make sure your generator runs every time you need it. Our preventive maintenance works like clockwork: scheduled oil, filter, coolant and diagnostic checks, load logs per genset, and alerts before a wear part is about to fail. When something does break, our field engineers get to site fast because they’re already in your city.
We offer one-off service calls, AMCs and Comprehensive AMCs — with operators where required. Parts are stocked across our 7 NCR branches so we’re not waiting on a delivery while your plant is dark.
Six things every customer gets.
Under 4-hour response
On-call service desk all year. AMC customers get under-4-hour response, most of the time, uniformly across all our Delhi NCR branches. Critical sites — hospitals and IT services companies — get a 2-hour SLA.

Frequently asked questions
How fast do you respond to a breakdown?
Two response SLAs: (1) Standard AMC — under 4 hours, most of the time, uniformly across all our Delhi NCR branches. (2) Critical-site AMC — 2 hours, for hospitals and IT services companies. Non-AMC breakdowns are handled same-day as capacity allows.
What counts as a 'critical site' for the 2-hour SLA?
Only hospitals and IT services companies — sites where even a short power interruption causes material harm (patient safety, SLA breaches). Sign-up includes a site assessment so we can pre-stock common spares and route the fastest engineer. Available as an add-on to Comprehensive AMC.
Do you service generators you didn't sell?
Yes. We service every major make — Cummins, Perkins, Caterpillar, Kirloskar, Mahindra, Ashok Leyland. Brand-agnostic is part of the point.
Do you cover HT gensets and parallel installations?
Yes — including 11 kV and synchronized multi-genset setups. Our engineers have delivered installations like 6 × 1500 kVA at HMC Halol and service them ongoing.
Service vs AMC — when does each make sense?
One-off service is per-visit billing — useful for ad-hoc checks or one-time issues. An AMC is a year-long contract that locks in priority response and (in Comprehensive plans) bundles parts. The full breakdown of contract types lives on the AMC page.
