Overview
The Sumec Firman SDG20FS is a 20kVA diesel soundproof generator built for continuous use where grid power is unreliable or unavailable. Its three‑phase output and compact soundproof canopy make it appropriate for commercial sites, small industries, and construction work requiring stable power.
Designed with a 50L fuel tank that offers long running periods, the unit delivers 220V/380V at 50Hz and maintains frequency and voltage within the specified limits for steady operation of motors and sensitive equipment.
The generator is protected to IP23 and comes in a transportable skid‑style package with dimensions and weight suitable for site moves. It is intended for applications that need durable, three‑phase backup or primary power.
Key features
- Rated Power: 20kVA three‑phase output (220V/380V, 50Hz)
- Fuel: Diesel with a 50L tank for extended runtime
- Soundproofed canopy: reduced noise compared with open frame units
- Robust build: IP23 protection class suitable for outdoor installation with basic weather protection
- Stable output: steady state voltage deviation ≤ ±2.5% and frequency control ≤1.5%
What can it power?
Typical load estimate for 16 kW rated output, keeping a 20% safety margin (≈ 13,333 W usable). Motors (fridges, ACs, pumps) need extra power for a few seconds at start-up — that is already counted.

Why diesel?
Diesel engines use less fuel per hour under load and are built for long daily running — the usual choice for offices, estates and anything above 10 kVA.

It sits in a soundproof canopy, so it is much quieter than an open-frame set — well suited to estates and offices. Place it outdoors on a level base with free airflow.

Yes. Every Sumec Firman unit we sell is new, in the original manufacturer's box, with its manual and accessories.
