GDW150P 148kVA Three Phase Diesel Generator

Description

Pramac GDW150P – 148 kVA Three Phase Diesel Generator

Perkins power. Mecc Alte output. Canopy quiet.

The GDW150P diesel generator delivers 148 kVA / 118.4 kW emergency standby and 135 kVA / 108 kW prime power from a Perkins 1106A-70TG1, a turbocharged six cylinder, 7.0 litre, water-cooled engine running at 1500 RPM. Output is delivered through a brushless Mecc Alte ECP34 2M 4C alternator in series star at 400/230 V, 50 Hz, three phase, 0.8 power factor, with class H insulation, IP23 protection, 92.9% efficiency at full load and voltage regulation held inside 1%. Nominal current is 195 A behind a 250 A circuit breaker.

The canopy version is a weatherproof galvanised sheet metal enclosure with residential silencer and high quality soundproofing, giving 68 dB(A) at 7 metres and a guaranteed sound power level of 97 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 3090 x 1100 x 1852 mm and weighs 1827 kg. An extra silent enclosure is available at 65 dB(A) at 7 metres.
