GDW35P 25kVA Single Phase Diesel Generator

Description

Pramac GDW35P – 25 kVA Single Phase Diesel Generator

Perkins power. Dedicated single phase output. Canopy quiet.

The GDW35P single phase generator delivers 25 kVA / 25 kW emergency standby and 22.8 kVA / 22.8 kW prime power from a Perkins 1103A-33G, a three cylinder, 3.3 litre, water-cooled engine running at 1500 RPM. Output is delivered through a brushless Mecc Alte ECP32 1S4 C alternator at 230 V, 50 Hz, unity power factor, with class H insulation, IP23 protection and voltage regulation held inside 1%. Nominal current is 99 A behind a 100 A circuit breaker.

The canopy version is a weatherproof galvanised sheet metal enclosure with residential silencer and high quality soundproofing, giving 64 dB(A) at 7 metres and a guaranteed sound power level of 93 dB(A). Large lockable lateral doors open the unit up for service, and the welded steel baseframe carries anti-vibration mountings, screwed support legs and a crane lifting hole. The canopy measures 2200 x 1020 x 1292 mm and weighs 970 kg. An extra silent enclosure is available at 60 dB(A) at 7 metres.
