GDW90P 89kVA Three Phase Diesel Generator (BT810TPA00L)

Description

Pramac GDW90P – 89 kVA Three Phase Diesel Generator

Perkins power. Mecc Alte output. Canopy quiet.

The GDW90P BT810TPA00H build delivers 89 kVA / 71.2 kW emergency standby and 80.8 kVA / 64.6 kW prime power from a Perkins 1104A-44TG2, a four cylinder, 4.4 litre, turbocharged, water-cooled engine running at 1500 RPM with mechanical governor. Output is delivered through a brushless Mecc Alte ECP32-2L4 C alternator in series star at 400/230 V, 50 Hz, three phase, 0.8 power factor, with class H insulation, IP23 protection, 90% efficiency at full load and voltage regulation held inside 1%. Nominal current is 117 A behind a 125 A circuit breaker.

The canopy version is a weatherproof galvanised sheet metal enclosure with residential silencer and high quality soundproofing, giving 60 dB(A) at 7 metres and a guaranteed sound power level of 89 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 2400 x 1040 x 1725 mm and weighs 1289 kg. An extra silent enclosure is available at 56 dB(A) at 7 metres.
