Open Type
Open (skid-mounted) generator sets are the most economical way to buy diesel power. Every component stays visible and reachable, which shortens routine maintenance and simplifies troubleshooting.
Overview
One platform, sixteen engine choices
A diesel generator set is a system, not a component. The engine determines fuel consumption and overhaul life; the alternator determines voltage quality and motor-starting capability; the controller determines how the set behaves on changeover; and the enclosure determines whether the site can be permitted at all.
Cunmi builds every set as a matched package. We select the engine for duty class, size the alternator for the largest step load on site, and configure the controller for the exact transfer and paralleling scheme the project requires.

Packaging Options
Choose the enclosure for your site
Silent Type
Silent (canopied) sets enclose the generator inside a zinc-coated steel canopy with high-density acoustic lining, reducing noise to a level that is acceptable in hospitals, hotels and residential neighbourhoods.
Container Type
Containerised generator sets are shipped as a complete power plant inside a standard 20 ft or 40 ft ISO container: genset, fuel system, exhaust, control room and switchgear all pre-integrated and factory tested.
