The LG CNS Gasan Data Center uses environmentally friendly green IT concepts to provide custom tailored services. The Center is a state of the art facility that meets the most advanced global standards by providing a complete infrastructure for customers.
By using green IDC cooling methods and providing a diversified coolant backup system, the Center can maintain individual temperature and humidity settings for each area. By using outside air for cooling, power costs are reduced, and centralized cooling methods ensure optimum cooling efficiency.
