![]() ![]() Keeping any electronic device cool is one of the most important issues relating to the long-term reliability of the product. This is particularly true of the Avionics in an aircraft given the costs for repair or replacement. We have received many comments regarding the warmth of the radios (especially on hot summer days) as installed in the center console of the SR20's and SR22's.
Our modification involves removing the factory installed fan and installing a Lone Star Cyclone 600 (squirrel-cage type fan) that was specifically designed to keep Avionics cool. We install this fan behind the Co-Pilot's instrument panel and run cooling hoses down to each unit in the console. This is not to imply that the fan installed by Cirrus is in any way inadequate. I am not an engineer and do not proclaim to be educated in the field as are the engineers at Cirrus. What I can attest to is that I have had customers tell me their radios feel warm/hot and they want to know if there is a solution. This modification is guaranteed to make your radios run cooler. Will it save you from premature failure of your radios due to heat related issues? I honestly can't say but given that the current flat rate repair on a GNS430 is $600 from Garmin, is it worth $1300-$1400 to keep your radios COOLER??????? I would be more than happy to discuss this topic in further detail. Todd Adams |
