Looking over a long history of Hennigan’s service to Canal Electric Company, I wanted to take the opportunity to commend you for many jobs well done! In an era of uncertainty, it is reassuring to have the certainty of reliability, professionalism, and the commitment of excellence in service.

In conclusion, it is Design Engineering’s recommendation to use Hennigan Engineering to clean any of the-RBS heat exchangers during RF-3 that need cleaning. Hennigan’s past performance plus their patented hydrolasing tip make them the logical choice to use here at RBS
