Your questions, answered
Frequently asked questions.
Which diesel generators does JMG supply in Nigeria?
Browse the FG Wilson, Eletromak and Mitsubishi ranges. Compare the model, duty rating and technical sheet, then request a quotation for the equipment and services your site needs.
What information helps JMG size a diesel generator?
Provide the equipment load list, motor starting requirements, operating hours, site location and any future expansion plans. A kVA figure alone does not describe all the conditions needed for correct selection.
Can I request a generator for a factory, hotel or commercial building?
Yes. Include the application and operating requirements in your enquiry. JMG can assess the generator, controls, installation and maintenance scope together.
How can I compare generator prices in Nigeria?
Compare quotations for equivalent duty ratings and scope. Check whether the enclosure, controls, delivery, installation and after-sales provisions are included. Ask for the current technical sheet and commercial terms.
