Direct rack-cooling solution for high-density servers
Airedale’s LogiCool packaged chillers can provide DX cooling to computer-room air conditioners and direct rack-cooling systems. They maximise the benefits of free cooling.
Airedale’s LogiCool range of packaged chillers for computer suites and server rooms can be matched with direct rack-cooling solutions from leading rack producers and also linked to airside cooling systems from Airedale and other manufacturers. They use R410A and are designed to maximise the use of free cooling by simultaneously delivering free cooling and mechanical cooling. The free cooling operates with as little as 1 K differential between ambient and return-fluid temperatures. Available in 20 and 40 kW cooling modules, with a single DX circuit, LogiCool is configured for outside installation. It provides flexible, multi-rack cooling by an individual unit or by a number of units with run/standby and optional sequencing capability. Energy-saving features include tandem digital scroll compressors combined with AireTronix controls technology and electronic expansion valves to offer fully modulating control. These units can operate in free-cooling mode most of the time. The ability of LogiCool to self-optimise and the very large surface area of the cooling coils, which lengthens the periods of free cooling so that more than 45% of the energy used by a conventional chiller is saved.
