I haven't seen it myself, but yes we do service a Lintern AC unit that cools the cab of an overhead crane. Very specialized equipment right down to the refrigerant. They have been very helpful when I've had to talk to them on the phone. I think that most specialized equipment works this way. The manufacturers want you to be their eyes and ears and they will tell you what to check. After a few tries, you pick up the differences and similarities. I've worked on quite a few cascade systems and all those manufacturers were very helpful as well.

190 degree ambient with peaks to 210? Sounds very unconfortable to work in http://hvac-talk.com/vbb/images/icons/icon15.gif

Just curious. They say those systems can operate on R-124 or 134a. I know 124 is a low pressure refrigerant. But, how do they run 134a at those kinds of ambient temps? Wouldn't you have like 400psi head with 30-40 suction?

Take R-124. Have been in a refinerey where it was open air outside ambient. Those units use R-134a.

Its gas compression. Tell me about wet compression if you don't mind.

You take breaks as much as you work??? Can it really be that hot? Is this the rebublican way? You just may be a closet democrat.

Yesterday, I went to our old office (we moved Wednesday) to finish cleaning it up and get every last thing out. Someone had stuck a Lintern catalog in my door handle (probably a sales rep) but their card was not there. Strange coincidence.

Those would have been ideal for a grain elevator job I did back in 97.

The main challenge was all the grain dust generated when 30,000 tons of grain would be loaded on a boat.
