Customer Comments

We use Ryben inverter in our House and it powers all of our household items. Thanks Kongu Engineers.

The UPS system has proven to be an excellent system and choice for Kalgan. We have experienced zero downtime or disruption to our business when the local power fails, which happens many times a day. We are very proud and happy with our solution and recommend Kongu Engineers for any companies.

This is to certify that Ryben 1000VA Sinewave UPS working at our business place working satisfactorily for last 4 Years and services rendered by the company are appreciable

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.
