Row
-DENCO indoor unit
Description of the unit
The
Row
-DENCO air-conditioning unit is an innovative and efficient system for mana-
ging hot spots in data centers, guaranteeing low energy consumption and possibility to
be used with HIGH DENSITY racks that generate extremely high loads, up to and over
40 kW/m² per rack. The use of the latest generation EC fans with brushless motors
ensures excellent performance in terms of low power consumption and low noise. N+1
dynamic management of the EC fans to optimise consumption and cooling system red-
undancy are available as standard.
On the
Row
-DENCO versions, the units are positioned in rows of RACKS, with a layout
so as to create cold aisles, where the cool air from the Rack Cooler is delivered, and
hot aisles, where the air heated by the electronic equipment housed in the RACKS is
discharged. These are individual units installed between the Racks in a row, so as to
absorb the local heat load of the servers.
On
Row
-DENCO versions, the air to be cooled is taken in at the rear of the unit directly
from the data center hot aisle (35 °C), giving considerable benefits in terms of both
energy efficiency and cooling capacity, before being cooled and then delivered into the
cold aisle (18-20 °C), in other words, at the front of the same rack where the air is taken
in.

Structure
Extremely compact structure that reduces overall dimensions, made from galvanised
steel plate with RAL9002 epoxy powder coating. The panelling is coated with an inno-
vative double layer of plastic, is lined on the inside with special soundproofing material.
Fans
The use of latest generation 225 mm diameter radial fans with EC brushless motors
ensures excellent performance and low power consumption. N+1 dynamic manage-
ment of EC fans is featured as standard, allowing operation at reduced flow-rate to opti-
mise power consumption. Moreover, in the event of a fault on one fan, the other fans
are operated at maximum speed to ensure the same cooling performance.
The fan section has been designed to allow rapid replacement in the event of faults,
thus reducing system downtime.
