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.
Tanis has a wide range of piston and turbine engine preheat products that include preheat kits and systems for engines manufactured by Honeywell (Garrett), GE, Pratt & Whitney, Safran (Turbomeca), and Rolls-Royce (Allison), that are approved for fixed-wing aircraft, including Pilatus and Viking, and helicopters from manufacturers such as Airbus, Bell, Enstrom, Erickson, Hélicoptères Guimbal, Leonardo, MDHI, Robinson, and Sikorsky. Tanis also produces preconditioning systems for oil coolers, gearboxes, fuel control units, mod motors, and hydraulic units. Piston-engine products include systems developed for Austro, Continental, Franklin, Jabiru, Jacobs, Lycoming, and Rotax powerplants.
The Hartzell umbrella of companies includes Hartzell Propeller, Hartzell Engine Technologies, LLC, Quality Aircraft Accessories, and AWI-AMI (Aerospace Welding Minneapolis and Aerospace Manufacturing) that form the general aviation business unit of Tailwind Technologies.
