Horizontal Air-Cooled Rack-Mounted Air Conditioners Units Range From 4,000 BTU To Dual 20,000 BTU Configurations
| Product Introduction COOL RACK Series rack-mounted air conditioner is a cabinet-level temperature control product specially designed for integrated cabinets data center, modular data center or high heat density data centers. It can be placed in the cabinet close to the heat source and can accurately handle the output of the equipment in the cabinet. The high sensible heat can effectively prevent the generation of local hot spots, reduce the return air distance, increase the return air temperature, and improve the energy efficiency ratio.
