INSTALLATION
The series is particularly suitable for installation in Data Centre of medium / small size with constant load.
DOWNFLOW VERSION (Under)
Typical installation is on the perimeter.
The units are placed along the perimeter of the Data Center. Air suction from the top of the unit and air
delivery in the underfloor void.
The air distribution is achieved by special tiles placed in front of the racks row, forming cold aisle for air
diffusion. On the rear of the racks is expelled the hot then aspirated by the unit.
For an optimal installation is advisable to provide the cold aisle containment.
Some solutions provide a service corridor around the server rooms where to place the units. In this case, it
is necessary to provide the air intake plenum for each unit. With this solution, all the space in the Data
Center is available for the installation of racks.

The series is also suitable for installation in UPS, Batteries, Distribution rooms and in all service areas of
the Data Center that need a service of conditioning.
