March 6, 2013  By Carey Fredericks

March 5, 2013, Valencia, Ca. - Hartzell Aerospace has been selected by Liebherr-Aerospace Toulouse SAS, Toulouse (France), to supply electric Environmental Control System (ECS) heater ducts on a range of new aircraft projects currently in development.

Hartzell will supply its NXT galley heaters for Bombardier CSeries* aircraft as well as galley and door heaters for Chinese COMAC C919 airliner.

Hartzell’s existing heater duct products are already the lightest on the market, and the company’s new Liebherr-selected, patent-pending NXT series heater ducts will be 40 percent lighter and result in 40 percent lower pressure drop than its existing, already-superior, lines. Hartzell’s unique design features result in low cost, low noise and low weight, while still maintaining high efficiency and reliability. The company’s compact heater ducts feature full temperature control and are available in round and custom housings for a large range of heat outputs.

Simon Shackelton, senior vice president of Hartzell Aerospace said, “This contract marks the extended expansion of our operations into the European market. We’re extremely pleased Liebherr-Aerospace’s executives have placed their trust in us to supply our superior ECS heater ducts on these projects.

“Liebherr-Aerospace’s decision is a reflection of our growing reputation as a leading supplier of specialized products for various engineered applications.”  


The heater ducts for this project will be supplied by Hartzell subsidiary Electrofilm Manufacturing Co. LLC in Valencia, CA.  Electrofilm is responsible for the design and manufacturing of Hartzell’s heater ducts, and together with AcousticFab LLC in Sanford, FL, and Industrial Tube Company (ITC), LLC in Perris, CA, comprise the Hartzell Aerospace group.
