GDW90P
Protect operations from costly outages with the Pramac GDW90P. Rated at 80.8 kVA prime and 89 kVA standby, 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 Perkins 1104A-44TG2 engine and Mecc Alte ECP32-2L4 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.

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.
