Localized cooling, hotspot elimination
The In-Rack is a compact and lightweight chilled water cooling unit intended for attaching to the rear doors of rack cabinets. Since In-Rack handles the heat load as close to the source as possible, it consumes only a little amount of energy.
Equipped with a set of redundancy options like hot-swappable fans, dual power supply, and uninterruptible power source, the In-Rack cooling door ensures the highest possible availability for mission-critical IT equipment.
The microchannel evaporator used in the In-Rack design allows achieving many advantages, including low airside pressure drops, higher cooling capacity, and noticeably less weight.
Low weight removes limitations of the previous generations of rack-mounted cooling doors and enables the use of In-Rack cooling solution for both greenfield and retrofit applications.
Hot-swappable EC fans
The In-Rack features hot-swap fan assembly that allows fan replacement on running units minimizing the downtime. When the fan goes offline, the remaining fans will compensate by increasing rotation speed.
350mm axial fans mounted in bellmouth housings and equipped with EC motors allow In-Rack to operate at part-load and optimize the overall energy efficiency.
Chilled water circuit
Upon request, chilled water circuit can be equipped with either 2-way or 3-way motorized regulating valves used to control the chilled water flow through the evaporator coil, as well bypass valve to enable constant flow.
Regulating valves supplied loose with the unit.
The control hub of In-Rack cooling unit constantly monitors the air temperature and humidity to avoid/minimize condensate build-up by regulating water flow thru the evaporator coil.
The system eliminates the possibility of water entry into the rack by means of dewpoint control and automatic condensate discharge system.
Enclosure and mounting
The In-Rack cooling door can be easily attached to any standard server rack (42U to 48U) and does not impact on the access to IT equipment installed in the rack.
With low weight only by 1/3 compared to competitors, the In-Rack unit does not create significant rack/-floor load, thus giving the customers a highly flexible installation solution. The slim design of In-Rack units ensures minimal impact into the hot aisle.
The In-Rack rack cooling door offers a wide variety of redundancy options: besides hot-swappable fans, the customer can benefit from dual power supply, either automatic or static transfer switch, and uninterruptible power supply installed directly into the server rack, and use these features to improve the availability of IT infrastructure.
The conventional approach to data center cooling using room-based cooling has practical limitations in high-density data centers.
The rack-based cooling strategy makes it possible to address high operating densities while maintaining redundancy characteristics.
For users with high-density server technologies, an In-Rack cooling solution will provide the excellent balance of high predictability, high power density, adaptability, and the best overall TCO.
