Page 4: Safety
User Manual iQdata Backcooler Safety General description The Backcooler is a high-performance cooling unit for cooling IT components, without additional fans. Particularly energy-efficient cooling is possible because of the low, air-side pressure drop. The heat is dissipated in the immediate vicinity of the origin, so that the room is not subject to thermal load. -

User Manual iQdata Backcooler Technical data Proper use The Back Cooler is an air/water heat exchanger and is mounted directly on the rear of the IS-1 cabinet. Particularly high energy efficiency is achieved by eliminating the fans. A special adapter frame can be used to mount on the server racks by other manufacturers. - Page 9 User Manual iQdata Backcooler Article number Height Width Door hinge Pipe module Article number 2000 7035 on right side from below 2000 9005 on right side from below 2000 7035 on left side from below 2000 9005 on left side...

Page 12: Description
User Manual iQdata Backcooler Description General information The Backcooler is mounted directly on the rear side of the IS-1 cabinet, preventing warm server exhaust air from entering the server room installation room. The thermal energy from the IT components is taken up by the Backcooler without any additional fans and is conveyed to the re-cooling system by means of the cold water contained in it. - Page 13 User Manual iQdata Backcooler Rack Backcooler air separator can be repositioned View from above 12 of 23 SCHÄFER IT-Systems Industriestr. 41 D-57518 Betzdorf Phone: +49 (0) 2741/283-770 sales@schaefer-it-systems.de www.schaefer-it-systems.de As on: 2.05.2017 (subject to technical changes)

Page 14: Appositioning The Cabinets Together
User Manual iQdata Backcooler Appositioning the cabinets together For appositioning the server cabinets, dismantle the sheet covering in the pipe module section. The appositioning is done at the same connection points as for fastening the side panels After the server cabinets are appositioned, re-install the sheet covering. -

User Manual iQdata Backcooler Connection to the cold water network Floor section, right door hinge Installation of pipes (Flexible hose) to the raised floor The connection from the Backcooler is done via flexible hoses, flat sealing 1" AG (DN 25). -
Page 16: Filling The Backcooler With Cold Water
User Manual iQdata Backcooler Filling the Backcooler with cold water The Backcooler is filled with cold water via the building network. For ventilating the heat exchanger, there is a vent valve (Schrader valve) above the door, which must be opened while filling to let the air escape from the cooling system. -
Page 17: Air Separation Of Hot Areas / Cold Area
User Manual iQdata Backcooler Air separation of hot areas / cold area For adjusting the air separation to the respective IT components, this can be moved. The sealing is done with special brush strips, which guarantee high airtightness. Thereby, the hot section in the rack can be kept particularly small and the heat emission in the room is reduced to a minimum. - Page 18 User Manual iQdata Backcooler Adjusting the air separation Loosen joints at the top and bottom on both sides; after that, the air separation can be shifted. Air pass partition plates To prevent air-side short circuits, special blank plates, height 1 HE, have been developed, which are arranged between the IT components.

Page 21: Connection Variants To The Cooling System
User Manual iQdata Backcooler Connection variants to the cooling system For separating the object network (primary) from the IT cooling (secondary), the iQdata Heat exchanger can be used. In this, a control system is integrated, which computes the dew point using humidity and air temperature and raises the setpoint of the IT cooling water temperature until no condensate can occur on the pipes and heat exchanger. -
Page 22: Backcooler Control
User Manual iQdata Backcooler The Tichelmann system is that the flowing water must cover the same pipe length all over. In the process, the lengths of the flow and return lines are considered together and for each Backcooler the pressure loss is the same, so that the cold water volume flow is spread evenly. - Page 23 User Manual iQdata Backcooler Temperature difference - control Temperature difference - control with room temperature - control 22 of 23 SCHÄFER IT-Systems Industriestr. 41 D-57518 Betzdorf Phone: +49 (0) 2741/283-770 sales@schaefer-it-systems.de www.schaefer-it-systems.de As on: 2.05.2017 (subject to technical changes)
