Our own brand
VOLTKA Generators
Cummins-powered diesel generating sets from 10 kVA to 2000 kVA, starting at KES 500,000, 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 2000 kVA, from KES 500,000
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 2000 kVA
Model names, smallest to largest. The range runs from 10 kVA up to 2000 kVA, but the model number is not the rating — ask us which set matches your load. Sizing is done against the kW your site actually draws, plus the surge your largest motor pulls when it starts.

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.
