Diesel Generators
Diesel generators from portable site sets through to containerised power modules rated in the thousands of kilowatts. Diesel earns its place on running hours: a set used daily repays the higher purchase price in fuel and service intervals, while one started a few times a year generally will not. Tell us the load and the duty and we will size it with you.
