Letorneau l-1350 A/C question.

I know there are a few in the mining industry here. I'm only an operator but just researching. They just replaced the ac units with a new mine air system that just doesn't keep up in 80 degree weather. The unit says 10,000 btu/hr and 800 cfm. I'm curious what systems other mines use and how well they cool. I cook in the cab when loading facing the sun. Just today we finally got some big wigs to come sit in it and feel how inadequate they are. They were shocked so hopefully they do something about it. Our shovels will freeze you out in the summer but we have always fought them on the loaders to upgrade.
