Product 02 / Power & backup

Five generator brands, one vendor who answers the call.

Kirloskar, Cummins, Caterpillar, Mahindra Powerol and Volvo Penta. We size the set against your actual connected load, build the foundation, run the exhaust, wire the AMF panel and hold the AMC afterwards. Nobody gets to blame the other contractor.

Supply drops, the panel senses it, the set cranks and takes load. We commission and time that sequence before handover.

01The brands

Five engines. One honest recommendation.

We carry all five, so we have no reason to push the wrong one. The engine gets chosen by your duty cycle and your load profile, not by whichever dealership pays best.

Mahindra Powerol compact silent diesel generator set
5 – 625 kVA

Brand 04

Mahindra Powerol

Compact footprint, low operating cost and minimal vibration. The one that fits when the plant room was designed before anyone thought about a genset.

02Size it right

Undersized trips. Oversized wet stacks.

A set running under about 30% load for long periods glazes its bores and passes unburnt fuel. Bigger is not safer, it is just more expensive and less reliable. Three answers and we will put you in the right band.

Indicative only. Final sizing needs your actual load schedule, starting currents and diversity factor. We do that at survey.

03Scope of supply

The set is the easy part.

Most generator disputes are about everything except the engine. Who poured the foundation, who ran the stack, who sized the cable. All six are ours, on one order.

Six things that decide whether it starts

A generator that will not take load on the night it is needed almost never failed on the engine. It failed on one of these six.

Foundation and anti-vibration

A reinforced plinth sized to the wet weight of the set, with anti-vibration mounts between skid and plinth. Skip this and the vibration travels into the slab and shows up as cracked plaster two floors away.

You send

  • Connected load schedule or the sanctioned load
  • Largest motor on site and its starting method
  • Plant room location and how far it sits from the panel
  • Noise constraints. Neighbours, hospital wards, night running
  • A site photo works if you have no drawing

You get back

  • kVA rating with the diversity and starting calculation shown
  • Two brand options where more than one fits the duty
  • Foundation drawing and plant room clearances
  • Exhaust route and stack height for the norms that apply
  • A fixed price covering supply, install, commissioning and year one
04Emissions & compliance

Compliant on paper and on the test run.

A non-compliant set is a sealed set. We supply CPCB IV+ rated engines and hand over the documentation with them, then run the load test on site so the numbers on the certificate match the machine in your plant room.

CPCB IV+ engines

Emission-rated sets specified against the norms current at the time of order, with the compliance certificate handed over on commissioning.

Stack height

Exhaust routed and the stack sized to the applicable rule for your set capacity and building height, not to whatever fits the shortest pipe run.

Acoustic limits

Enclosures selected against the noise limit at your boundary, which is a different number from the one on the brochure measured at one metre.

Load bank testing

Stepped load test at commissioning with readings recorded, so you know the set takes full load before you need it to.

Documentation pack

Test certificates, warranty registration, wiring schematics and the O and M manual, handed over as a set rather than chased for six months.

Statutory support

We prepare what the pollution control and electrical inspectorate submissions need and follow them through rather than handing you a folder.

05Where they run

Different buildings, very different duty.

A hospital set and a factory set are sized on completely different logic. One is about how fast it takes load, the other is about how long it holds it.

Standby generator power for a hospital block
Critical

Hospitals

Theatres and ICU cannot wait out a crank cycle. Sized for fast load acceptance with the changeover timed and recorded at commissioning.

Standby, fast pickup

Generator installation supporting a data centre
Mission critical

Data centres

Sized with headroom for UPS charging on top of the running load, which is the step most quotes forget entirely.

Standby with UPS headroom

Prime duty

Manufacturing plants

Motor starting currents dominate the sizing here, not the running kW. We calculate against the largest motor and its starter type.

Prime, high motor starting

Generator serving a commercial office and retail building
Commercial

Commercial buildings

Chillers, lift banks and escalators are the load that matters. Often two sets in synchronisation so one can be serviced without going dark.

Standby, often synchronised

Low noise

Residential towers

Noise at the boundary decides the enclosure, and night running rules decide whether it can run at all. Both get checked before we quote.

Standby, acoustic critical

Backup generator supporting a hotel property
Hospitality

Hotels

Guests notice two things: the lights flickering and the noise at 2am. Kitchens, lifts and HVAC come first on the changeover, and the enclosure is picked for the guest rooms above it.

06Before you ask us

Questions we get on every enquiry.

Short answers, no brochure language. If yours is not here, call the desk and ask.

There is no single answer, which is the reason we carry five. Cummins and Caterpillar lead at the top of the range and on load acceptance. Kirloskar and Mahindra Powerol are strong on low-noise, low-footprint installs. Volvo Penta earns its place in the mid range where the set runs often rather than sitting idle. Tell us the duty and the load and we will name one, with the reason attached.

Not by taking your sanctioned load and rounding up. We work from the connected load schedule, apply a realistic diversity factor, then check the largest motor's starting current against the set's ability to hold voltage during that step. The starting check is what actually sets the rating on most industrial sites.

No, and this is the most expensive mistake in the category. A diesel engine running lightly loaded for long stretches does not reach proper combustion temperature, so unburnt fuel and oil collect in the exhaust. That is wet stacking, and it costs you power output, fuel and eventually an overhaul. Oversizing buys you a worse machine at a higher price.

Yes, when you take the turnkey scope. Foundation, anti-vibration mounts, exhaust piping and stack, acoustic treatment, AMF panel, power cabling and earthing are quoted as one line. This is where cheap quotes hide their gaps, so compare our number against a competitor's total, not against their machine price.

Yes, for the brands we carry. We start with a condition survey and a load test, list what needs correcting before the AMC begins and price that separately. Scheduled visits come with a written checklist, and we hold the spares line across all five brands. You will not be signed onto a contract that quietly inherits somebody else's deferred repairs.

Yes. Synchronisation lets two or more sets share load, which gives you redundancy for servicing and lets the plant run only the capacity it needs at any hour. It costs more in panel and control than a single large set, and it is usually the right call for malls, hospitals and anything where going dark is not an option.
