Innovativ and efficient - SCHÄFER IT Rack Solutions

n Full integration as a compact unit
n From 4 to 21 kW usable cooling capacity
n 100 % circulating air operation
n Thermally independent of the ambient air
n Parts carrying cooling water in separate housing
With UNIQLE, SCHÄFER is systematically implementing the principle of a
cooling system integrated in the server rack. The decision for integration
is a logical step.
Argument 1: Energy efficiency
n Low pressure loss, pump rating correspondingly lower
n Long fan lifetimes as fans are not mounted in heated sections
Argument 2: Space efficiency
Server space is not unlimited! And through the trend to higher and
higher computer performance accompanied by a greater packing density,
server racks must guarantee a maximum of space efficiency.
This enables the maximum computer density per m² of floor space to
be achieved.
Comparison of floor space
n UNIQLE (integrated cooling system),
floor area in mm (W x H x D): 800 x 2240 x1200
n Server rack of 800 mm width with side cooling solution (300 mm),
floor space in mm (W x H x D): 1100 x 2200 x 1200
Floor space needed for 100 U
n UNIQLE 1.92 m²
n Server rack 3.96 m²
The 5 Elements
n SP54 Rack

n Partnership Management
Please note: Pipe work and a cold water generator are to be
provided by the customer. Air-intake temperature is regulated
by RMS with integrated control. Operation and configuration
via SNMP or http.
