Tanis Aircraft Products, a division of Hartzell Propeller, has added to its portfolio of pre-heating solutions with the recent approval of its supplemental type certificate (STC) for the complete Daher TBM 700 model series. The company also received parts manufacturing authority (PMA) approval for the system’s kit.
Building on the Tanis range of engine pre-heating systems for Pratt & Whitney turbine engines, the Tanis TBM STC will cover all Daher TBM 700-series turboprops, from the original TBM 700 through the recently certificated TBM 980, applying to all serial numbers and model years over the TBM’s more than 35 years in service.
The Tanis TBM kit offers a multipoint configuration through a self-regulating system to deliver preheating to the turboprop’s overall powerplant installation, including the:
- engine
- prop reduction gearbox
- oil cooler
- fuel control unit
- accessory gearbox
- battery, among other components.
The system also provides avionics and cabin preheating, with LED power indication and circuit overload protection, all positioned to meet the requirements of TBM owners and pilots.
JJ Frigge, president of Hartzell Propeller, said, “As colder weather approaches, maintaining reliable aircraft operations becomes increasingly important. This new Tanis system gives TBM owners and operators a comprehensive preheat solution designed to support easier cold-weather starts, while providing protection and supporting reliability of critical aircraft systems. Beyond the operational benefits, it also creates a more comfortable experience for passengers by allowing the aircraft to be warm and ready before they ever step on board.”
Engine and complete aircraft preheating offer advantages beyond pilot and passenger comfort:
Reduced engine wear and mechanical stress. Cold starts can induce strain on internal components, seals and accessories. Preheating reduces thermal shock and helps components reach operating temperatures in a gradual manner, while reducing cold-weather-related wear and tear.
Increased battery health, and more. Modern preconditioning systems may extend heating beyond the propulsion system to include gearboxes, hydraulics, avionics and cabin areas. This helps protect critical systems, improve safety and increase overall aircraft readiness in cold climates.
Easier engine starts and reduced warm-up time, especially in cold weather. Preheated aircraft reach operating temperatures faster, reducing run-up time, fuel consumption and unnecessary ground operation. This allows operators to spend less time warming up and to bring passengers on board with less waiting time.
Improved avionics performance. The modern flight deck’s electronic hardware performs better in an environment with a stable, moderate ambient temperature inside the cabin. Where dispatch reliability is critical, a preheating system supports the long-term health of advanced equipment.
The Tanis TBM system will be available in both North American voltage (115 V) and European voltage (230 V). Kits can be ordered directly through the Hartzell Preheat website or through an authorised reseller or distributor. The Tanis system comes backed by a five-year warranty.
