Cool arguments
against climate stress
Rittal high performance cooling and liquid cooling packages
are important links in the IT security chain. As packaging
densities continue to rise, active rack control is indispensa-
ble. Added to this is the fact that IT racks are often posi-
tioned in rooms without adequate air conditioning. This
means stress for the sensitive electronics. Consequently,
active and direct enclosure climate control is the optimum
cooling choice. The benefits are twofold: When climate
control and ventilation are ideal, computing processes are
able to run efficiently. This means an uninterrupted data flow,
which in turn translates into non-stop productivity.
Passive cooling
The perforations in the doors or openings
in the base/plinth and roof ensure
maximum air throughput via convection
in conjunction with the equipment
fans.

Active cooling (room)
The fans built into the rack ensure a permanent
through-flow. In this way, heat
energy is emitted directly to the ambient
air. Specifically for low and medium output
ranges.
Active cooling (rack)
This variant allows reliable climate control
of sealed racks even in difficult
ambient parameters such as heat and
dust. Ideal for medium output ranges.

High-performance cooling
High heat losses resulting from high
packaging densities (e.g. blade
server technology) are reliably and
efficiently dissipated on a rack-specific
basis using products from the
liquid cooling package (LCP) family.
