Tanis Aircraft Products is a company of “firsts”. Since starting our business in 1974, we were the first to develop engine-mounted preheat systems for piston engines, first to offer helicopter preheat, first to offer turbine preheat, and the first to meet the rigorous requirements for FAA Supplemental Type Certification. Staying first means we will continue to be responsive to the changing needs of our customers as technology in the industry evolves. Doing this requires a staff of highly qualified and well trained specialists.
