Co2 racks

[joe magee]

Looking for info/training on Co2. The company I work for just built it's second C02 rack for a supermarket and it will be started Monday. I know it's been used as a refrigerant in markets in Europe for some time. Let me know if it's popular in your country. Any info would be great. :)

Have you looked at R744.com? It has some info on there.

Are the racks subcritical or transcritical? DX or liquid recirc? Got any photos? What comp manufacturer are you guys using?

[joe magee]

It's both a dx for low temp and a recirc for med temp. Not sure if sub or trans critical. Copeland compressors for both the top side and the C02 side. RDM controller. Will be starting rack tomorrow. I'll learn it fast.

So how's the start up going?

[joe magee]

Start up went well. No real problems with the racks or the systems. Last one started in Atlanta had an E-2 this store has an RDM. New controller new problems. My old friend from Source is there doing the start up. I'm going by this week to check on it. The problem is very few people have the knowledge to work on it.
