Re: Plant Decommissioning
Bring it up in 3-5c stages over a week. hover around 0/+1c for a week the refrigeration will naturally dehum the air
Then take it to +10c for a week and it should be fairly dry by then.
Re: Plant Decommissioning
Having, sadly, been through this before there can be a problem with thawing frozen cold storage rooms.
I am assuming that this is an older plant. I had a problem with one with fiberglass insulation. We went to thaw out the room to install an Ice Rake system. The ceiling was full of ice and started sagging when we turned off the refrigeration. We had to turn the cold back on and finish the work in the cold. If you can run the engine room at a higher suction pressure doing what r.bartlett suggested will do well.
I would be very careful.
