We run a 88' american texair gas with electric ir panels and it's a monster. We have had issues with it here and there, but it's always been easy to fix if you have the right person on the other end of the phone, and you can use a multimeter. Ours is a 48", 5' 10' 5'. I run ours at 380 on the gas and 800 on the radiant panels and run the belt at 25 and that will hold at least 1200 an hour without stacking the shirts all funky. I think these dyers are awesome, especially if you think about the number of shirts that have gone through this dryer of ours and the small amount of downtime. We had a transformer blow last week and it blew 3 fuses on our dryer and with a phone call and the multimeter, we had it up and running in 15 minutes.
Hey EB, what's full temp on the gas settings? I ran ours at 400 gas and 1000 on the radiant panels at one time! That was way too hot for what we were doing and the belt speed was at 30 then too.
I've heard of people covering their texairs with refrigerator type skin to further insulate them to keep them cooler. One guy in town supposedly put those panels they use for the freezers and coolers at sam's club and it made his shop 15 degrees cooler in the summer.
