100 kW Generators for Sale

Serious Capacity for Demanding Sites

Once a site’s power needs move beyond what a smaller unit can comfortably handle, a 100 kW generator steps in to fill that gap without tipping over into full industrial-scale equipment. These 100 kW diesel generators are built around dependable, proven components that hold steady under continuous demand, making them equally at home providing standby cover during a grid outage or supplying prime power on a site with no mains connection at all.

You’ll sometimes see this size listed as a 100 kW genset rather than a generator, though the two terms describe exactly the same equipment. As a leading stockist, we keep a broad range of generators held in our own warehouse, so a 100 kW diesel genset can typically be delivered far sooner than an equivalent unit ordered directly from a manufacturer.

Built for Quiet, Confined Locations

Larger sites often sit closer to other businesses, loading bays, or residential streets than their scale might suggest, which makes managing noise a genuine priority rather than an afterthought. Our 100 kW silent generators are housed within weatherproof, acoustically treated canopies, cutting noise output down to a level that won’t cause problems for neighbouring occupiers. A 100 kW silent diesel generator of this kind suits sites where planning restrictions, lease conditions, or simply good practice call for a quieter, self-contained footprint.

The canopy does more than dampen sound, too. It keeps rain, dust, and general debris away from the engine and alternator, which helps reduce the amount of upkeep an exposed unit would otherwise require over its working life.

Powering Heavier 3 Phase Equipment

At this size, a 100 kW 3 phase generator is capable of running genuinely demanding equipment, from CNC machinery and cold storage plant to larger HVAC systems that a smaller supply simply couldn’t sustain. A 100 kW 3 phase diesel generator gives site managers meaningful headroom above entry-level and mid-range units, while still remaining practical to install within a typical commercial or light industrial plot.

A 100 kW 3 phase genset is a frequent choice for both hire fleets and permanent installations, and every 100 kW 3 phase diesel genset we supply is fitted with a control panel that makes checking load, run hours, and general status straightforward rather than a guessing exercise. Since our 3 phase generators all run at 50Hz, they suit UK sites and export markets that share this frequency standard equally well.

Getting the specification right at this scale benefits from real experience, and our team brings more than 50 years of combined knowledge to that conversation, whether you’re planning a new installation or replacing equipment that’s reaching the end of its service life. As an authorised reseller, our pricing on this range is the best available anywhere in the UK, without any compromise on the quality of the equipment or the support that follows the sale.

Because we hold genuine stock rather than relying purely on manufacturer lead times, a diesel generator from us won’t leave you waiting longer than necessary.
