Hartzell Acquires Pre-heat Product Maker Tanis
Hartzell Propeller will move Tanis production to Ohio.

Hartzell Propeller has purchased the assets of Tanis Aircraft Products, a Minnesota-based manufacturer of engine and aircraft preheat systems for fixed- and rotary-wing aircraft. The Tanis brand will become part of Hartzell’s heated products, including systems for propeller de-ice and preheat for piston and turbine engines, helicopters, batteries, avionics, and aircraft cabins. Tanis engineering, sales, and administrative staff will continue to be based near the Anoka County Airport in suburban Minneapolis, but manufacturing operations will move to Hartzell in Piqua, Ohio.
