my vote goes to tony, I love stories of catastrophic failure, stuff blowing up, bearings seizing, one thing I left out is, all the
aerotech machines that I have seen recently have a thick insulating blanket that wraps the HX, I would imagine this along with the steel under the insulating blanket would protect against any issues of deadly shrapnel, anyways what are the chances of standing in the box when something like this happens, I spend a very small amount of time in my trailer while the unit is running.
so shawn, lets imagine a machine is only going to be used in a warm climate, like florida, so cal etc, would you have used a direct exhaust HX like
AT currently uses for their design on your machine?? if this so called dangerous HX was mounted under the truck wouldn't that make it safe, the only real benefit to the zen stuff is you don't have to mount the HX outside the truck and worry about it freezing or you don't have to route truck exhaust into the box.
for the record I am not a fan of either the
AT or V systems, I think both are kinda white elephant units, personally I would rather save my 401k
and buy a used machine for cash, so I don't have debt, or if I had more cash I would rather have more than one unit so they can be 2 places at once. there are plenty of cheaper machines capable of producing a steady 230ATM which is plenty for the jobs I do. however I do like to get shawn fired up all in good fun of course. dale earnhardt once said "doesn't matter if they are cheering or booing, they are making noise"
