Stephill SSDP33 Diesel Generator – 33 kVA (2021) Used

The Stephill SSDP33 is a robust and reliable 33 kVA super-silent diesel generator, designed for dependable prime or standby power across commercial, industrial, and site applications. Built in the UK by Stephill Generators, this unit combines proven Perkins engine performance with a durable acoustic canopy for low-noise operation.

Delivering 33 kVA standby and 30 kVA prime power, the SSDP33 provides stable 400/230 V three-phase output at 50 Hz, making it ideal for construction sites, events, backup power, and temporary installations. The integrated 280-litre bunded fuel tank offers excellent run times, while the skid-mounted design ensures ease of transport and positioning.

The generator has been upgraded with a 63 amp three-phase socket, replacing the original 32 amp outlet. This provides greater compatibility with site cabling and distribution equipment. The generator’s electrical output remains unchanged, and it will still supply up to its rated current (equivalent to a 32 amp set) in line with manufacturer specifications.

With a 2021 build, CE certification, and a strong reputation for reliability, used diesel generator from Stephill is a solid choice for customers seeking dependable mid-range diesel power in a compact, professional package.
