New technologies are increasing heat loads in today’s server rooms and wiring closets, which often lack adequate cooling. The APC InfraStruXure InRow SC is a self-contained cooling solution that maximizes availability within small IT rooms. This energy-efficient unit lowers operating costs by using variable speed fans, capacity modulation, and an in-row form factor. The InRow SC's plug-and-play design allows for rapid installation without the need for running refrigerant lines or providing remote heat exchangers. The predictive failure notification and high head pressure protection features, along with hot-swappable fans, improve the availability of IT equipment.
