OptiCool® Overview

OptiCool® Overview

System Description

The OptiCool® data center cooling system provides close-coupled cooling at the heat source for low- to high-density cooling applications.  OptiCool® is a low-pressure, refrigerant-based system which is adaptable to any computing equipment rack.  The OptiCool® Cool Door® system attaches to the equipment rack and can support a variety of heat load and redundancy configurations while delivering unprecedented simplicity, performance and energy efficiency. OptiCool® is vastly superior to conventional data center cooling, which includes computer room air conditioning, hybrid containment and in-row sytems.  The OptiCool®  data center cooling system provides exceptional energy efficiency (up to 95%) for a broad range of cooling applications from 2 to 30 kW per rack.  Each OptiCool® refrigerant pump system delivers 210 kW of cooling capacity yet is only 40″ wide offering a dramatically reduced cooling footprint.  In addition, each Cool Door® can be configured to support in-rack cooling redundancy at 20 kW per rack.  OptiCool® can support both raised floor and non-raised floor environments.
