Dual Cool
X2C0
For redundancy in critical applications, the SmartCool
dual cool X2C0 offers two different cooling mediums,
air cooled DX and chilled water, within the same case.
The X2C0 system is managed by the Airetronix
microprocessor to select which medium acts as the
primary source of cooling or which acts as back-up,
should the primary source fail or is unable to cope with
the heat load.
W2C0
For applications where a water cooled system is
preferred over air cooled, the SmartCool W2C0
comprises two different cooling mediums within the
same case: DX water cooled, as in the W2W2 system,
and chilled water, as in the C000 system.
The Airetronix microprocessor elects which medium
acts as the primary source of cooling and which as
back-up, if the primary source fails or is unable to cope
with the heat load.
W2F0
The W2F0 system includes a free-cooling coil in
conjunction with the evaporator. In low ambient
conditions, particularly in relation to the high
temperatures and continuous system operation of a
server environment, the W2F0 system will run with
minimum energy. At times of higher ambient,
sophisticated Airetronix controls technology will
modulate the 3-way water regulating valves to
transition from free cooling back to mechanical cooling.
Typically the SmartCool W2F0 single circuit free-
cooling system uses 46%* less energy than a standard
air cooled DX system.
