Technical Specifications
Key Features

Rugged, practical and reliable diesel generator. Whether it’s for a remote construction site, powering some site offices or backing up your workshop, this is engineered to do the job.
Designed by the technical team here at OMC specifically for demanding New Zealand conditions. Every feature is intentional: like the silent canopy made from fully galvanised sheet with heavy duty 120um powder coating, or the bunded fuel tanks that come standard for safety and environmental protection. Fitted exclusively with Deep Sea Electronics controllers, for the ultimate in reliability. To maximise protection, we opted for marinized, triple-dipped LeRoy Somer LSA series Alternators to make these seriously robust.
The ST30KBT-HD is suitable for a wide range of applications but primarily designed to be tough, simple and reliable for the construction and rental markets. With a 4 Pole AVR Controlled alternator this provides mains quality power, ensuring your electronics are safe. This is also suitable to charge battery energy storage systems such as those connected to solar panel systems.
