Mmmmmm interesting ...
I guess the folks at Eurocopter have changed the A/C system on the EC145 form that used on the Bk117 series .... 'cos that was capable of sending ice crystals out of the ducts ... you could freeze a side of beef in the back if you wanted too!
So whats the story .... have they gone away from the Garrett system over to a R134a evaporative system or what???
