Oil & Gas
Remote mines, drilling rigs and oilfield camps run on diesel as prime power, not standby. Cunmi builds heavy-duty, dust-tolerant packages with oversize cooling and dual fuel filtration.
The Challenge
Oil & Gas power requirements
In a mine, the generator is the grid. That means prime-power ratings, continuous duty at high ambient temperature, and a service philosophy built around planned shutdowns rather than unplanned failures.
Our mining packages use marine-derived engine platforms with high torque rise for crusher and mill starting loads, plus a 100 % oversize radiator and two-stage fuel filtration for sites running on heavy or contaminated fuel.

Solution Highlights
What makes the difference in this application
Prime-power rated
Continuous 24/7 duty at 40 – 50 °C ambient with derate documentation.
Dust and heat tolerant
Oversize radiators, cyclonic pre-cleaners and dual fuel filters.
Heavy-load starting
High torque rise for crushers, mills, conveyors and hoists.
Field service
Containerised workshops and multi-unit spare-part kits for remote camps.
How projects are delivered
From load schedule to commissioning in oil & gas
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.
