If it's rotting out and is going to be replaced the new system is going to have to conform to current codes and standards. If they are now using HDPE crates then that's what needs to be considered in the new design.
What was done before isn't relevant if you're putting in a new system.

The system is protecting fruit stored in bins in a controlled atmosphere building. The system is rotting out and needs to be replaced, I can't find a specific clause in the codes that say's replace it as it currently is - the problem being a dry grid. To further complicate the problem the original classification was a Class II (fruit in wood bins), today those bins are HDPE - Group A Plastic. With this information would you agree that you can't replace the system as originally installed? Jim Johnston, P.E.
