The FAA and EASA have granted supplemental type certificate (STC) approval for installation of Hartzell Propeller’s Tanis helicopter preheat systems on the Airbus H135, including EC135T1/T2/T2+/T3 models and the EC635T2+. The preheat systems are available in two voltages: 115 VAC for the U.S. and 230 VAC for Europe.

Tanis preheat systems help operators perform protected engine starts in cold weather on both piston- and turbine-powered aircraft, contributing to aircraft longevity, reliability, and safety, according to Hartzell.
