American Power Conversion (APC) this week announced a series of small footprint coolers for data center servers that are able to chill up to 30 kilowatts per rack.The InfraStruXure InRow RC is a modular cooling box that is installed next to the IT equipment rack in small computer rooms or large data centers. It delivers as much as 30 kilowatts of cooling to the IT equipment. The InRow RC consists of a half-rack-width chilled water unit with variable speed fans. It can be managed with APC's InfraStruXure Manager.The InfraStruXure CDU is a flexible chilled water distribution system designed to work with the InfraStruXure InRow RC unit. It offers flexible and joint-less piping that reduces the risk of water leakage in overhead installations. Its flexible cooling lines let users grow and change their infrastructure as their needs change.The Rack Air Containment System (RACS) is a modular enclosure designed primarily for blade servers. It allows cooling of moderate, high and ultra high density heat loads and works in conjunction with the APC NetShelter SX rack and the APC InRow RC cooling unit to provide maximum cooling. The RACS attaches to the rear of one or more NetShelter SX racks and to the InRow RC cooling unit. Air exhausted from servers passes through the cooling unit.In addition to its InfraStruXure cooling systems, APC also makes a number of other systems for cooling computer rooms and data centers (see the list on its Web site).APC recently expanded into data center monitoring with the acquisition of NetBotz, a company based in Austin, Texas, which makes IP-based monitoring appliances.
