Well these are a little more powerful then the 4000 and dont take up as much floor space. Run you about $5500.

Sanyo also makes them.

It only cools 3.9kW maybe one rack of gear depending on how much you have on it, I think a full rack of servers can generate about 10kW of heat. You looking for a backup in case your Liebert units go down again? ----- Original Message ----- From: Bob Fronk To: NT System Admin Issues Sent: Tuesday, August 12, 2008 3:53 PM Subject: Backup AC units I have had two Liebert units fail in the last month. Yesterday's failure caused 4 hours of downtime. I am looking for backup unit recommendations. I am looking at the APC ACPA4000, but I am not sure it is large enough for my main center. Opinions and experience from the list appreciated.
