The Pramac GDW420V is a commercial three-phase diesel generator delivering 336.8 kW prime. With a Volvo diesel engine and a Mecc Alte ECO40 1S4 C alternator, it gives businesses and industrial sites a strong platform for backup power, site power and engineered generator installations.
Protect operations from costly outages with the Pramac GDW420V. Rated at 336.8 kW prime, it is designed for commercial standby, industrial backup and site power. The set can be matched to the real load, motor-starting demands and operating environment rather than selected on nameplate size alone. The Volvo diesel engine and Mecc Alte ECO40 1S4 C alternator form a well-matched mechanical and electrical package for long-term standby or prime-power service. Integrate it with automatic transfer switching, remote monitoring, distribution and site fuel systems to create a complete power solution. Order the standard package or specify a custom build with a stainless-steel canopy, hot-dip galvanised skid base, super-silent enclosure, synchronising controls or an open generator set. CPS supports the full project—from load review and generator selection through to switchboards, fuel transfer, compliance testing and ongoing maintenance.
