	CoolAdd - Cooling of up to 8000 watts CoolAdd is a further innovation in combating the problems of over-heated computer centres. The hot output air generated by the high-performance servers is intelligently cooled and the room?s thermal management system is therefore noticeably relieved. CoolAdd? is an easy to mount add-on set that simply replaces the rear doors of the server rack and connects to the computer centre?s thermal management infrastructure. Technical data For server racks: from 2000 mm height from 600 mm wide Depth 160 mm Balancing out thermal loads in computer centres. Effective cooling of up to 8000 Watts under the following conditions/temperatures: Server output air: 35? C, Tserver out CoolAdd air outlet temperature: 22? C, TCoolAdd out Cooling water feed: 14? C, Twater feed Cooling water return: 20? C, Twater return 4 fans / n+1 redundancy
	CoolAdd replaces the server rack?s rear doors and is also adapted to the existing rack?s structure. A connection to the computer centre?s cold water system is required.The air/water heat exchanger is positioned in the fixed installed part of the upgrade kit and is connected to the server rack via the frame. Four fans are integrated into the rear door, which provides access to the cabling for the rack components. CoolAdd is just one of the numerous innovations of the Knurr High Density Cooling Solutions family.
