Warrior LDG15S3 15 kVA 3-Phase Silent Diesel Generator – Electric Start – by Bimson Power

Three-Phase Diesel Power for Serious Workloads

The Warrior LDG15S3 is a 15 kVA three-phase silent diesel generator built for the jobs single-phase units simply can't handle — industrial loads, commercial backup, large-scale event power, three-phase machinery on site. Powered by a 1064cc V-twin diesel engine running at 3000 RPM, it delivers 13,000 watts maximum and 12,000 watts running output across three phases, with a 35-litre tank capable of up to 20 hours of run time at 50% load.

Stable Voltage Under Load

A built-in Automatic Voltage Regulator (AVR) holds the output voltage steady as the load changes — particularly useful when starting motors, pumps or compressors that briefly draw heavy inrush current. The AVR responds in real time to stop the voltage sag that would otherwise upset other equipment running off the generator at the same time. Well suited to power tools, machinery, lighting, heating, refrigeration and standby use. For very sensitive electronics like medical equipment, precision lab gear or some computing setups, an inverter generator (such as the Champion Atom Fusion) is a better fit.

Quiet Operation Thanks to the Silent Canopy

Enclosed in a noise-reducing canopy with anti-vibration mountings and a chip-resistant matt finish, the LDG15S3 runs at 75 dBA at 7 metres. Not technically silent, but well below what you'd expect from a 15 kVA diesel running flat out — quiet enough for sustained operation on a busy site without the usual diesel growl.

Standby-Ready with ATS Input

Equipped with an Automatic Transfer Switch (ATS) input port for seamless backup integration. Paired with the optional ATS panel, the generator fires up automatically when the mains drops and shuts down when power is restored — no manual intervention required. Ideal for commercial premises, workshops, farms, or any operation that can't afford downtime.

Versatile Three-Phase Connections

One 32A 3-phase Red outlet (415V) for industrial three-phase loads, plus two 16A 230V Blue outlets for single-phase equipment — plug everything in and the generator balances the loads for you. The IP23-rated control panel includes Intelligauge, voltmeter, fuel gauge and electric key start. Nylon wheels and frame-mounted handles keep the 260kg unit manageable for site relocations, and the heavy-duty industrial frame is built to take knocks.

2-Year Warranty as Standard

Backed by a full 2-year manufacturer's warranty.

Why Diesel?

• Lower Cost Per Hour – Diesel is more energy-dense than petrol or LPG, giving you more kWh per litre. For sustained or heavy use, diesel is the cheapest fuel to run.
• Longer Runtime – A 35-litre tank gets you 20 hours at 50% load — more than double what a comparable petrol unit would deliver.
• Built to Work – Diesel engines tolerate sustained heavy loads and tough conditions better than petrol. Less stress, less wear, longer life.
• Fewer Maintenance Headaches – No carburettor, no ethanol decay, no spark plugs to foul. Clean oil and clean filters keep it going.
• Safer Storage – Diesel is far less flammable than petrol, easier to store on site, and won't go off in the tank between jobs.

A Word on the Branding

You'll see this generator described as both Warrior and Bimson Power across the trade. Warrior Power Equipment is the original brand — the LDG-series model numbers are theirs. Bimson Power is the parent company, now bringing the range under its own name. Same engine, same chassis, same UK technical support team in Wigan.

Shipped Empty — Important

All generators are shipped empty. The unit will not contain any Fuel or Oil on arrival. You'll need to add diesel and engine oil before first use — full instructions are in the operator's manual. A break-in period of around 10 hours at no more than 75% load is recommended before applying heavier loads.

All units are manufactured to EU Stage V emissions standards, with CE and UKCA certifications. IP23 ingress protection rating. Designed for balanced loads — when running unbalanced loads, please verify specific equipment requirements. Specifications correct at time of publication and may be altered without notice in the interest of technical improvement.
