Vortum Marine Genset – V18.5 (18.5KVA)
Made for Leisure Boats. Designed to Perform
Meet Vortum. Zenith Engineering’s new range of super silenced, marine generators, engineered to meet the unique demands of leisure marine vessels. Combining the renowned reliability of Isuzu-powered marine generators with cutting edge sound attenuation technology for quiet efficient, dependable performance at sea.
Reliable Marine Power
Australia’s most forgettable marine generator. You won’t hear it, You’ll rarely see it. Finally, a generator so reliable it practically disappears.
Vortum is not just a generator, it’s peace of mind, performance, and quiet efficiency in one powerful package. Carefully crafted to deliver silent, steady, performance when you need it most.
Precision-egineered for Silence and Durability
Each Vortum generator is enclosed in a purpose-built sound-attenuated cabinet, designed to minimize noise without compromising airflow or performance. Key features include:
- High-grade construction: Fabricated from 2mm powder-coated aluminium for superior corrosion resistance and a lightweight overall unit.
- Innovative airflow design: Directional flow is managed through specially designed baffle end pieces, eliminating the need for commonly used noise-leaking vents.
- Premium sound insulation: Lined with 32mm thick acoustic foam, embedded with 2mm rubber wavebar for maximum sound absorption.
Proven Power and Performance
At the heart of every Vortum generator is the robust Isuzu engine, seamlessly paired with a MeccAlte alternator from Italy. Combined with our custom-built cooling package, this results in a marine generator system that is:
- Exceptionally reliable
- Quiet in operation
- Built to endure harsh marine environments
The Vortum Range
