Product Description
DESCRIPTION
Data subject to change without notice.
All sensitive electronic equipment
requires a stable environment for
optimum performance. The
Ecosaire ® Precision Environmental
Control system provides the best
possible protection for any
application.
The Ecosaire® product line is made
up of feature-rich, energy-efficient
premium products that are available
in sizes and configurations to suit
several mission critical applications
such as Data Centers, Server
Rooms, Telecom Switching Rooms,
Medical Applications, MRI Rooms,
including Museums and Archival
Storages. Custom-built units serve in
corrosive industrial process environ-
ments for Control Rooms, Electrical
Equipment and Transformer Rooms.
Ecosaire® contains unique, highly
engineered subsystems that no other
manufacturer duplicates, ensuring
continuous simultaneous control of
temperature, humidity, air purity,
and airflow at each operating site.
Ecosaire ® performs with the high-
est energy efficiency through intelli-
gent design: less energy wasted on
undesired latent cooling, on-demand
dehumidification, and the state-of-
the-art Supervis
aire ® Control
System. These new controls offer
maximum design flexibility, network-
able units, BACNET
TM , and
MODBUS TM compatibility. This
allows remote monitoring and alarm
logging from either a graphics display
panel, personal computer, or via
modem.
The Ecosaire ® product line offers
the maximum in environmental con-
trol performance and the lowest life-
cycle cost of ownership.
Stable environmental conditions
are further ensured by on-demand
dehumidification. Unlike convention-
al computer-grade systems that con-
stantly dehumidify,
Ecosaire
®
elimi-
nates the costly process of removing
and then replacing moisture.
The Supervis aire ® Microprocessor
Controls provide extremely user-
friendly, programmable monitoring
and control for all
Ecosaire ®
Precision Environmental Control sys-
tems. Individual
Ecosaire ® units can
be connected on a built-in local area
network together with a supervisory
panel complete with a backlit graph-
ics display for robust, redundant
environment control. At the same
time, the network can be connected
to a personal computer supervisory
system, or to a BACNET
TM
, or MOD-
BUS TM network.
The LCD panel is large and easy
to read (4 x 20 characters) and the
simple layout provides an easy-to-
use interface for the operator.
English language menus (other lan-
guages available) and built-in diag-
nostics walk the user step-by-step
through the monitoring and control of
the system.
A powerful 16-bit microprocessor
ensures high program-execution
speed and efficient real-time man-
agement of even the fastest tran-
sients.
The computer-site conditions and
utilities will determine the type of
environmental control units selected.
A cooling-load calculation based on
design criteria should be performed
according to standard air-condition-
ing practice. The calculation should
include the heat gains of: exterior
walls and windows; area exposed to
unconditioned spaces (i.e. partitions,
ceilings, and floors); people; lighting;
and all computer and auxiliary
equipment. With this information
the type, size and number of
Ecosaire ® units can be selected to
best match the equipment configura-
tion in the computer room.
Allowances for expansion and redun-
dancy should be considered at this
time.
While many important factors
require evaluation when designing a
computer room, the most important
are security, expandability, location
within the building, proximity of relat-
ed data processing operations and
proximity to outdoor air-conditioning
components. Computer rooms are
best located in a central part of a
building so as not to be affected by
outside temperature and humidity.
When a room must be designed with
an outside wall, the wall should be
insulated and windows should be
kept to a minimum. Thermopane
windows should be used to prevent
condensation. Equipment access
through doors, elevators, etc., as well
as elevator capacity, must be
carefully considered.
