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.

The Tanis silicone pad heating elements can provide heat to engines, gearboxes, hydraulics, avionics, and batteries to extend the lifetime of critical driveline components, reduce torque oscillations, and maximize battery and starter life. Verticon visitors can see the Tanis products at the Hartzell exhibit.

“These Hartzell Propeller STCs for our Tanis-brand preheat systems expand coverage for Airbus H135 helicopters,” said Hartzell president J.J. Frigge. “The entire Tanis team truly cares about enhancing the reliability, safety, and utility of your aircraft, despite the cold weather.”
