1.2 Product
Description
STULZ CyberRow systems are available in Water
cooled, Water/Glycol cooled or Air cooled Direct
Expansion (DX) confi gurations. DX based CyberRow
systems are designed to operate with R410A
refrigerant.
DX based CyberRow cabinets are 12” wide. The
cooling capacity in BTU/Hr will depend on the
compressor size. Refer to the unit nameplate to
identify the capacity of your system.
NOTE
STULZ
CyberRow
systems have been designed
to capture and neutralize heat within close-
coupled rack-based environments. Any use
beyond what is described in this manual is
deemed to be not intended. STULZ is not liable
for any damage resulting from improper use.
The functional modes of operation are cooling and
dehumidifi cation which provides localized cooling to
offset hot spots in data centers.
The CyberRow system captures high temperature
(hot aisle) discharge air from adjacent rack-based
IT equipment and reintroduces it as conditioned air
through the front of the unit (cold aisle).
The system is equipped with highly reliable EC
(Electronically Commutated) fans which offer
considerable energy cost savings and long life. Using
an electronically commutated permanent magnet DC
motor, AC inverter whine is eliminated. Fan speed is
continuously adjustable via a signal from the system
controller without the use of VFD’s. EC fans offer
energy effi cient, quiet, low vibration operation.
An advanced
E²
series microprocessor controller
is mounted inside the CyberRow electric box. The
controller provides the following features: input/output
monitoring status, full integrated control of cooling
and dehumidifi cation, multi-unit control and remote
communication with a Building Management System
(BMS). The controller may interface directly to a
BMS, allowing the ability to monitor the performance
of the air conditioner and adjust operating
parameters.
The
E²
user interface display panel is typically
factory mounted on the front access panel of the unit.
Refer Section 4.0 for detailed instructions on
operating the system controller.
