CO2 below 5bar
Hi, I'm a fridge engineer who has recently taken over the maintenance and service of a supermarket with a new Co2 system. I have been told to ensure that the system never goes below 5bar during operation/maintenance because of the danger of forming 'dry ice'.
My question is, if this does happen will repreasurising the system 'melt' the dry ice? if not what do we do to ensure the dry ice is out of the system before we continue?
Any advise would be great as this is the first time I have delt with Co2.
Cheers Rowan

Re: CO2 below 5bar
Search for the danfoss "phase change" video, it explains a lot.
