VOLTKA Generators

Cummins-powered diesel generating sets from 10 kVA to 3000 kVA, starting at KES 280,000, with a two-year warranty. VOLTKA is the brand EmersonEIMS sells. Every other make on this site we maintain, repair and stock parts for.

Cummins inside

Every VOLTKA set is Cummins-powered. That is why the parts position below matters: the engine in the machine we sell is the engine we hold the deepest catalogue for.

10 kVA to 3000 kVA, from KES 280,000

A shop standby set through to prime power for a factory or a mine. What your own set costs depends on the size your load needs, the enclosure and the controller, all of which go in a written quotation.

Two-year warranty

Every VOLTKA set carries a two-year warranty. Supplied from our Nairobi warehouse, transported, installed and commissioned with its changeover panel, anywhere across the 47 counties.

The VOLTKA range — 10 kVA to 3000 kVA

Smallest to largest, with the rating each one carries — the number in a VOLTKA model name is its kVA. The range runs from 10 kVA up to 3000 kVA. Sizing is done against the kW your site actually draws, plus the surge your largest motor pulls when it starts. Every size is available two ways: open, for a plant room or an enclosure you already have, or closed in a canopy where the set stands outdoors or near people.

Prices are published up to 2,000 kVA. Above that the engine, alternator and canopy are specified against your site, so those sets are quoted on application rather than listed.

The parts position behind the machine

374 catalogued parts across 11 Cummins engine families, each listed with its manufacturer part number and the engines it fits. A generator is a fifteen-year purchase, and the question that usually decides it is whether parts will still be there in year eight.
