 Now Available for the Lancair Evolution, ES, Legacy, IV and PropJet Aircraft!


Heat is the most efficient method of keeping ice from forming. Until now thermoelectric de-ice technology has not been available for general aviation aircraft. Alternative solutions were created to keep wings free from ice but Therm-X™ leads the way with technology for the future. Therm-X™ is the heated leading edge solution.

Evolution heaters start with a mold of the conforming leading edge shape of the wing. E-glass is then laid up in the mold, followed by the graphite heater elements. A heat sensing RTD is integrated into the heater and then the lay-up is completed with an outer layer of E-glass. The result is a beautiful piece of technology that can accept paint to match the leading edge of the surface it is installed on.

RDD is the exclusive distributor of Therm-X™, a proprietary electro-thermal system designed by Kelly Thermal Systems and adapted for the experimental market by RDD. Therm-X™ is simple by design insofar as it has no moving parts, requires no maintenance, requires no messy and expensive de-icing solution and best of all—Therm-X™ provides an inexhaustible supply of ice protection (and peace of mind for encounters with inadvertent icing conditions).

Therm-X™ is a graphite foil laminate applied to the leading edge of the wing and horizontal stabilizer. Electronic heating elements embedded within the laminate are powered by a 75 volt/100 amp alternator. The result is 7,500 watts of digitally controlled energy coursing through two heating zones to keep the wings free of ice. The leading edge "parting zone" receives constant heat while the "shed zone" is managed by a digital controller to receive a heated cycle to disbond ice so it can be aerodynamically whisked away virtually eliminating runback. Therm-X™ is used like a heated pitot system. The entire Therm-X™ system only weighs approximately 40 pounds.
















In response to our customer’s needs we developed our windshield de-ice solution. RDD’s windshield system utilizes a glycol pump and reservoir to provide adequate windshield de-icing when your defrost simply can’t keep up.Call for more information and model specific applications. 541.504.0305
