GDW420V
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.
- Diesel generator for standby or prime power applications
- Configurable canopy, controller and fuel-tank options
- Electric start and generator control-panel integration
- Designed for commercial, industrial and facility backup power
Industry-leading components, fully supported in Australia
Pramac
Pramac is a leading global manufacturer of stationary and mobile power generation equipment, founded in Casole d'Elsa, Tuscany in 1966. Now part of the Generac group, Pramac engineers diesel, petrol and battery energy storage solutions trusted by rental houses, mining sites and emergency services in over 150 countries.
Deep Sea Electronics
Deep Sea Electronics (DSE) has been designing intelligent generator and battery management controllers from Hunmanby, UK since 1975. Their controllers — including the iconic DSE 4520, 6020 and 7320 series — set the global standard for AMF / ATS automation, remote monitoring and over-current protection.
Volvo — Engine
Volvo Penta is the industrial engine division of the Volvo Group, headquartered in Gothenburg, Sweden. Volvo Penta TAD and TWD series engines are specified on Pramac's mid-to-large industrial gensets, known for outstanding fuel economy, low emissions, and exceptional cold-start performance — backed by Volvo's global parts and service network.
Mecc Alte — Alternator
Mecc Alte is the world's largest independent alternator manufacturer, headquartered in Vicenza, Italy since 1947. Their brushless synchronous alternators are renowned for exceptional voltage regulation, high efficiency and long service life — the engineering backbone of countless premium gensets.

Almost every conversation about generator sizing starts with two numbers: kVA and kW. They sound similar, they're closely related, and they're almost always mis-used. The beer-glass analogy below is the fastest way to get them straight in your head — and once you do, every spec sheet in the catalogue suddenly makes sense.
A generator is really three machines bolted together: an engine, an alternator, and a controller. They each do one job, and they all have to talk to each other for the unit to behave properly.
Almost every customer who asks us 'should I get diesel or petrol?' gets the same answer: it depends on the duty. For occasional camp / weekend use under 8 kVA, petrol is cheaper to buy and lighter to move. For anything that has to start reliably after sitting unused — backup, standby, prime-power — diesel wins, almost always.
