Expert answers about generator runtime, sizing, and operational best practices for UAE construction and industrial projects
Yes, industrial diesel generators are designed for continuous 24/7 operation with proper maintenance. Prime-rated generators run continuously at 70-80% load indefinitely. Standby units limit continuous operation to 200-500 hours annually. UAE's extreme heat requires 10-15% derating and enhanced cooling systems. Regular maintenance every 250-500 hours ensures reliable continuous operation.
Oversized generators cause wet stacking, carbon buildup, and increase fuel consumption by 20-30%. Operating below 30% load leads to incomplete combustion, engine glazing, and premature wear. In UAE, oversizing wastes fuel and increases rental costs significantly. Optimal efficiency occurs at 70-80% load. Right-sizing prevents operational problems and reduces costs.
Prime-rated generators run 24 hours daily with unlimited annual hours at 70% load. Standby generators operate 1-2 hours weekly for testing, 200 hours annually for emergencies. Continuous-rated units handle 24/7 baseload power. UAE construction sites typically run generators 10-16 hours daily, with proper maintenance ensuring longevity.
In UAE, renting is more cost-effective than buying for projects under 2 years. Rental eliminates maintenance costs, storage requirements, and depreciation losses. Purchase makes sense for permanent installations or 5+ year requirements. Consider rental includes 24/7 support, spare units, and no capital investment. Most UAE contractors prefer rental for flexibility.
