Some installation specs call for nylon threaded bolts or rod like this: http://www.usplastic.com/catalog/ite...4519&catid=668 I have used it, but have found the nylon easy to work with but it's easy to strip the threads if you're not careful. Refrigeration Hardware has some fiberglass reinforced rod which works quite well and is a lot stronger (See p.125): http://www.rhsparts.com/pdf/2007GENP...ag%20Bolts.pdf

Do you know of any design or type of support/hanger that minimizes this problem? What do mean? Are you talking about using all thread to go thru the ceiling and using pipe hangars? I like mounting uni-strut with pipe hangars. Depending on what's going in there you would be flirting with danger of having everything being eaten by acid. I would use all stainless steel hardware.

Just make sure the suction line is insulated properly, glue the ends of the armaflex to each other, secure it to the box, and make it look nice
correct layout of refrigeration piping in walk-in freezer Good evening to everyone. Most of the time I see that in walk-in freezers, the suction and liquid lines connected to the evaporator go immediately up and through the ceiling panel, exiting the walk-in as soon as possible. Is it correct to run the same lines across the walk-in and then though the wall panel? Does the low temp (-20F) may have some effect on the pipe insulation and/or the liquid refrigerant going through the liquid line? Thank you for any responses.
