S.R. Kamalanathan- Chennai

My office is protected by a Ryben UPS. It has saved my equipment from surges, spikes and blackouts on numerous occasions. The best UPS to me is Ryben.

Our total experience with Kongu Engineers has been excellent from the time we placed the order through to the after sales support. The team were not only very professional but took a hands-on personal approach to understand our business and to meet our specific requirements with the UPS. This has given us great piece of mind and security for our business and our customers.
