High Performance Computing (HPC) cooling technologies are moving into the enterprise sector. Data centers face major costs for cooling based on running increased workloads and thermal requirements. Data centers have traditionally used chillers, evaporative cooling towers, pumps, Computer Room Air Conditioner (CRAC) units and Computer Room Air Handling (CRAH) units to cool their infrastructure. Data centers are starting to integrate Direct Liquid Cooled (DLC) solutions to meet stringent energy standards, reduce costs, and increase cooling efficiency. Both traditional air conditioning and DLC are needed to meet data center cooling needs.

Organizations need to consider Capital Expenditures (CAPEX) and Operating Expense (OPEX) to determine when to use air conditioning, a DLC solution, or a hybrid solution in their data center. This paper compares the CAPEX and OPEX costs of using traditional air cooling solutions from STULZ USA with a hybrid solution that uses both STULZ air cooling and CoolIT DLC solutions.
