Plan on the cooling equipment having a fixed life of 10 years. Most systems will last longer with regular maintenance. Many older server rooms have cooling equipment that uses the refrigerant R-22. This refrigerant is in the process of being phased out to protect the ozone layer.
Two refrigerants that are replacing the obsolete refrigerant are R-407c and R-410a. Be smart – plan and budget to replace the old R-22 equipment before you are forced to.
Liebert brand equipment typically has a wait time of 4 – 6 weeks, so planning is critical.
