The AgustaWestland AW119 Koala and variants of the Eurocopter EC155 are the latest helicopters to be added to the list of aircraft for which Tanis Aircraft Products offers preheat systems. Bob Krueger, the company’s president, told AIN, “We’ve been doing preheat systems for general aviation since 1974 and about 20 years ago added the helicopter products. At this point we have about 50 different preheat configurations for various helicopters.”
According to Krueger, a complete Tanis rotorcraft preheat system consists of several specifically engineered heating elements that can be affixed to the engine oil reservoir and sump, hydraulic reservoir, reduction gearbox, accessory case, fuel control unit and other components. Each system is designed to protect critical components from cold starts, reduce the likelihood of damage, and to shave minutes off time to launch. “When factoring in all costs, including time and fuel, reduced wear and faster launch times, a Tanis preheat system is a money-saver for helicopter operators of any size,” he said.
