Engineered for Long-Term Reliability

At the heart of the Pramac GSW 22kVA is the Perkins 404D-22G engine, a compact, 4-cylinder diesel engine known for its fuel economy and long service life. It offers a prime power output of 20kVA and a standby rating of 22kVA, giving you flexibility for both continuous and backup power requirements.

The generator is paired with a high-performance Mecc Alte alternator to ensure stable voltage and frequency across varying loads. This makes it well-suited for use in sensitive environments where consistent power is crucial, such as medical centres, data hubs, or agricultural facilities.

Its weatherproof, sound-attenuated canopy offers protection from the elements while significantly reducing operating noise, making the unit ideal for installation in both urban and rural settings.

Simple to Use and Easy to Monitor

Designed with user convenience in mind, the Pramac GSW22 features a digital control panel that provides clear and accurate information at a glance. The panel allows you to monitor vital stats such as output voltage, frequency, oil pressure, engine temperature, and run time.

Operators can easily start and stop the unit, set schedules, or integrate remote start and monitoring options if required. Whether you’re on-site or monitoring from a distance, the GSW 22kVA provides complete control and visibility over your power source.
