rack-mounted cooler system for computers
Customer wants a computer rack-mounted cooler system for his computers, which dissipate about 15kW of sensible heat. Door-mounted coolers on computer racks mostly use chilled water rather than fridge, and as there is no in-house (24-7) chilled water on tap for this project, it would mean sourcing a suitable smallish chiller unit. Well, two chiller units, with the second one in standby setup.
1) Has anyone installed this kind of system, in the range of 15-25kW chiller plant, serving rack-mounted coolers (FCUs, basically)?
2) Any suggestions/recs, as regards the chiller make or a rack/cooler+chiller package?
3) The water-type systems boast cheaper run-costs but I suspect that this being quite a smallish load, the install price for a duty-standby chiller set up is a chunk more than 3x 10kW Daikin DX systems. Anyone looked at this and have some comments?

Yeah, that's a commonly installed system. Please contact Aquacooling http://www.aquacooling.co.uk/ . They will also supply a system for leak prevention under negative pressure.
Don't forget that a leak in the door coil would spray the computers.That's where a negative pressure system comes handy.

Rittal do both versions. a DX door or roof mounted cabinet cooler or a water cooler version

They also do a very high spec server room cooler but that will be well outside your budget
