Regular maintenance is essential to ensure the reliability and longevity of your generator system. Our preventive maintenance programmes are designed to identify potential issues before they become costly failures, helping businesses reduce unexpected downtime while maintaining optimal equipment performance.
Our engineers perform comprehensive inspections, routine servicing, and performance checks to ensure every generator continues operating safely and efficiently.


Proper installation is the foundation of a reliable power system. Desol provides complete mechanical and electrical installation services for generator sets, ensuring every system is installed according to engineering standards and project specifications.
From equipment positioning and cable termination to electrical integration and system configuration, our experienced engineers manage every stage of the installation process with precision and professionalism.


Every generator system must be thoroughly tested before it is placed into operation. Our Testing & Commissioning (T&C) services ensure that equipment performs according to design specifications while meeting safety, quality, and operational requirements.
We conduct detailed inspections and functional testing to verify system readiness, providing clients with confidence before project handover.


Unexpected equipment failures can disrupt operations and result in costly downtime. Our engineering team provides professional troubleshooting, repair, and overhaul services to restore generator performance quickly and efficiently.
Whether your generator requires component replacement, engine rebuilding, or a complete overhaul, we deliver practical engineering solutions that extend equipment lifespan and improve long-term reliability.
Every project is managed through a systematic process to ensure quality, efficiency, and customer satisfaction.
