Evans Cooling Systems' Podcast Examines Benefits of Waterless Cooling Technology for Rotax Engines

SUFFIELD, CT--(Marketwire - November 18, 2009) - Evans Cooling Systems, patent holder and manufacturer of the only commercial waterless engine coolants, has produced a podcast focused on the benefits of waterless cooling technology for Rotax engines, which are popular in small aircraft and in UAVs.

A recent FAA revised Special Airworthiness Bulletin (SAIB) recommended that waterless coolants be used in certain Bombardier-Rotax engines. The podcast addresses the potential issues of conventional ethylene-glycol/water coolant use in Rotax 912 and 914 series engines if the engine coolant exit temperatures exceed 120°C. Dangers include possible coolant losses, engine overheating, knocking, engine damage or in-flight shutdown.

The podcast details the advantages of using waterless coolant in these engines, including the higher boiling point of Evans waterless coolants -- above 180°C at atmospheric pressure. This provides a wide separation between its boiling point and the operating temperature of the system, avoiding the danger of overheating and possible engine shutdown.

Evans Cooling Technology Podcast Series focuses on the latest trends and developments in engine cooling. This podcast can be downloaded at For more information on Evans waterless coolants, visit the Evans website at, or call +1.860.668.1114.
