Now available is a Tanis preheat system for the Rotax 912 series engines.
The Tanis 110v electric heat system weighs under a pound and is extension-cord friendly, drawing only 2 amps. “Strategic placement of the heat probes is just as important as the total amount of heat applied,” said Bob Krueger, president of Tanis. “The system is balanced to the 912’s needs and raises temperatures 50° to 60°F above ambient in about four to five hours.”
That is also the conclusion reached after a series of tests performed by the Rotax Owner Assistance Network. The Tanis system was run through a series of cold-soaking tests, and the engine’s startup torque requirements and general behavior were also documented. ROAN officials further asked what the difference in start performance would be in still air or with a wind chill, and they ran separate tests, with and without an Insulated Cowl Cover (a custom-fitted “blanket”). Using temperature probes, strain gauges, and color infrared photography, the ROAN team put the Tanis system through its paces in another of their Product Review video tests. The free, 11-minute ROAN Product Review video is available on the ROAN site.
The Tanis 912-series engine preheating system is available in the United States from Lockwood Aviation or Leading Edge Air Foils. In Canada, Bully Hawk Aero Performance is the place to go. Price is $649.
