## Description

Hartzell Preheat brings together the established Tanis, Reiff, and SwitcheOn brands to help pilots and operators prepare aircraft for cold-weather flying. Built on the experience of Tanis Aircraft Products and Reiff Preheat Systems, the business offers solutions designed to protect engines and critical systems, reduce cold-start wear, and improve aircraft readiness. Its products serve piston and turbine aircraft, as well as rotorcraft and fixed-wing applications.

Tanis provides certified and PMA engine and airframe preheat systems, including options for engines, cabins, avionics, and batteries. Reiff specializes in modular, PMA-approved preheat systems for piston-engine aircraft, with configurable installation options and replacement parts. SwitcheOn adds remote control for compatible preheat systems through a mobile app and LTE connectivity, with scheduling and temperature-based activation.

Hartzell Preheat also offers technical information, application guidance, installation options, warranty registration, FAQs, and customer support resources. Its solutions combine focused preheating with broader aircraft preconditioning, helping users prepare equipment for demanding cold conditions. The brand’s offerings are supported by Hartzell Propeller’s engineering, manufacturing, and global support resources.
