Manufacturing
From steel rolling lines to food processing and textile mills, Cunmi supplies reliable standby and cogeneration-ready sets that keep production running through grid disturbances.
The Challenge
Manufacturing power requirements
Industrial loads are unforgiving: a voltage dip can scrap an entire batch. Our industrial packages are specified with high short-circuit capability and generous alternator margins so that motor starting does not pull the bus down.
For plants with high thermal demand, we also supply heat-recovery packages that turn exhaust waste heat into process hot water or steam, cutting total energy cost.

Solution Highlights
What makes the difference in this application
Motor-starting capability
Alternator sized for direct-on-line starting of large induction motors.
Parallel with grid
Import/export control, soft loading and zero-export configurations.
Heat recovery ready
Optional exhaust heat exchangers for process hot water or steam.
Power quality
Low THD alternators and optional harmonic filters for sensitive lines.
How projects are delivered
From load schedule to commissioning in manufacturing
The same three stages run on every order, whatever the configuration: engineering before the quotation, a documented load test before packing, and support after the set is on site.
Step 01
Engineering and sizing
Load schedule, starting currents, ambient and altitude derating are worked through before a rating is proposed — the alternator is sized for the largest step, not the average.
Step 02
Factory build and load test
Assembly, wiring and paint in one works, then a four-point load bank run at 25 / 50 / 75 / 100 % with the test sheet serial-numbered to the set.
Step 03
Shipping, commissioning and support
Export packing, documentation and commissioning guidance, with spare-parts supply and remote diagnosis for the life of the installation.
