Service Scope & Technical Engineering Specifications
Looking for a cost-effective alternative to purchasing new equipment without compromising on operational reliability? Generator Dubai is the UAE's trusted specialist in used and refurbished diesel generator sales, purchases, and instant cash buyback. From 30 kVA up to 1500 kVA, every pre-owned generator in our inventory undergoes a rigorous 80-point engineering overhaul and complete resistive load-bank certification inside our Sharjah testing facility, backed by our comprehensive warranty.
We never sell untested equipment. Every refurbished generator is coupled to our industrial resistive load bank and tested at 100% rated capacity for 2 hours, verifying oil pressure, temperature stability, and alternator voltage regulation under simulated desert heat.
Completed your civil project and have surplus diesel generators or decommissioned site equipment? We offer fair market evaluations, instant bank transfer payment, and provide our own crane trucks to safely remove equipment from your site anywhere in the UAE.
