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 effi-
cient premium products that are
available in sizes and configurations
to suit any application - even corro-
sive industrial process environments.
Ecosaire®contains unique, highly
engineered subsystems that no other
manufacturer duplicates, ensuring
continuous, simultaneous control of
temperature, humidity, air purity and
air flow 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 Supervisaire®Control
System. These new controls offer
maximum design flexibility, network-
able units, BACNETTM, and
MODBUSTM 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 Supervisaire®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 BACNETTM, or MOD-
BUSTM 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.

DESCRIPTION
Air-Cooled Direct Expansion
The Ecosaire®unit operates its refrigeration system as needed to
control room conditions.
Heat is transported via refrigerant-vapor flow to an outdoor air-cooled
condenser. The refrigerant liquifies in the condenser and returns to the
Ecosaire®unit.
Outdoor condensers are rated for 95°F (35°C) ambient with optional
models available for higher or lower ambient temperatures. They are
constructed of copper tubes and aluminum fins. A factory-wired control
panel is provided for field connection. Fan cycling and pressure-
actuated fan speed control maintain head pressure of either compressor
down to -20°F (-29°C). Optional flood-back controls are available for
either 30°F (-34°C) or -40°F (-40°C) operation.
See Installation - Piping for details.

Water-Cooled Direct Expansion
The Ecosaire®unit operates its refrigeration system as
needed to control room conditions.
Heat is transported via refrigerant-vapor flow to an inter-
nal water-cooled condenser. The refrigerant liquifies in
the condenser and re-circulates.
Water is pumped through the condenser to carry the
heat away. Proper flows and and temperatures of water
or other fluid must be provided by others. See
Installation - Piping.
The cooling water entering the unit must have a mini-
mum temperature of 65°F (18°C). Contact the factory for

and pump control boxes are provided.
When the outdoor temperature is below
60°F (16°C), the Ecosaire®unit operates
its refrigeration system to move heat into a
flow of glycol. Refrigeration condensing
pressure is controlled by pressure-con-
trolled throttling valves.
Heat is transferred via pumped glycol-
fluid flow to an outdoor heat exchanger.
Whenever refrigeration is not needed, the
glycol flow is diverted to internal air heat
exchangers to transfer as much heat from
the room as possible. This extends the
compressor off-time.
When the outdoor temperature is below
45°F (7.2°C), the Ecosaire®unit does not
use the refrigeration system. The glycol
flow is diverted to internal air heat
exchangers and transfers all the heat from
the room to outdoor air.

Moisture Migration Building Construction
Ecosaire®July 2007 15
Data subject to change without notice.
DESCRIPTION
In order to prevent moisture migra-
tion, the room (including the ceiling
plenum, if any) must have a sealed
vapor retarder. Rooms with concrete
walls or floor should be painted with a
rubber- or plastic-based paint. Doors
should seal tightly and must not have
grilles in them.
Light fixtures must be selected to pre-
vent overheating, and should not allow
room air to escape into the ceiling
plenum.
Because of the small number of per-
sonnel in a typical computer site, out-
door air should be reduced to less than
5% of the total circulated air. If outdoor
air is introduced, it must be filtered. The
effect of bringing in outdoor air must be
added to the cooling and dehumidifica-
tion loads.
Measures should be taken to prevent
dirt and dust from affecting equipment
reliability. Printers, bursters, copy
machines and other paper handling
equipment should be located in areas
removed from disc drives and similar
equipment.

public access should be avoided. Locate outdoor units in an area of clean
air away from steam, hot air, or fume exhausts.
Units installed on roofs should be mounted on steel supports in accordance with local codes. A concrete pad is
sufficient for ground installations.
Provide clearances as shown below. Insulate hot-gas tubes where they might be accidentally touched.
Lifting holes are provided at the top of the support legs. The nuts and bolts securing the unit to the crate are
used to mount the lower support leg sections and horizontal braces to the unit. Assemble the outdoor unit accord-
ing to the instructions provided with it.
The outdoor heat exchanger should not be enclosed within a solid fence or wall, since such structures prevent
adequate air flow. If a fence or wall must be installed, it must be no closer to the condenser than shown above,
no highwer than 6 ft (2 m) and must not extend lower than 12 inches (30 cm) above grade. Fences lower than
12 inches above grade may cause recirculation of heated air and a corresponding reduction in performance.

Important! - Inspect your unit immediately for shipping damage.
Claims for shipping damage must be made with the shipping company.
NOTE: Horizontal-flow and Vertical Flow Condensers are not inter-
changeable. The fans of horizontal-flow condensers must not face into
the prevailing wind.
Notify the carrier immediately if shipping damage is suspected. If internal dam-
age is suspected, indicate “contingent on internal inspection” when signing for
the shipment. Keep copies of all documents, including photographs of any
damage.
For units with a remote heat exchanger, select a suitable location for the
outdoor unit, where it will not be subject to damage. Outdoor condensers
(with Ecosaire unit of Cooling Type = A) must have no more than 100 ft. (30 m) of tube (one way) connecting to the Ecosaire
unit. Areas subject to heavy snow and ice accumulation should be avoided. Areas subject to public access should be avoid-
ed. Locate outdoor units in an area of clean air away from steam, hot air, or fume exhausts.

Data subject to change without notice.
Poor return-duct design can prevent proper
dehumidification by causing uneven air dis-
tribution over the evaporator. Reduced
capacity and/or equipment damage may
result.
It is very important to allow straight length
in the return duct as shown. There should
be no elbows, transitions, offsets, or other
flow interruptions closer than 2.5 X WIDTH of
the return duct opening.
If turning vanes are not used in elbows,
allow a length of straight duct equal to at
least 5 X WIDTH.
The straight length is not required for units
with top or bottom return air connections.
Return Duct
Important!
Poor duct design can
reduce the amount of air
delivered.
Duct design must conform to the
ASHRAE low-pressure, low-velocity
duct standards. If there is a ques-
tion concerning duct design, sizing,
choice of materials, air velocities,
or static pressures contact
Ecosaire for assistance.
Air velocities should be kept low
to allow good air movement and
low noise. Higher static pressures
result in higher power requirements
and increased noise. The maxi-
mum external static pressure is
specified for each unit. Static
pressures higher than specified
may reduce air flow below the mini-
mum acceptable value.
Select grilles, registers, and dif-
fusers for low static pressure loss,
required throw, and specified air
flow. Choose hardware resistant to
deterioration due to chemicals in
the pool enclosure.
Δ
Duct material
The Ecosaire®unit is suitable for
use with any duct material, subject
to the requirements of this section
and standard practice. Standard
galvanized steel duct is recom-
mended.
All elbows must be equipped with
aerofoil turning vanes and acoustic
insulation.
Where located in areas below
room temperature, ductwork must
be insulated on the outside with 2
inch fiberglass wrap with FSK fac-
ing. All ducts must be designed to
be dry. All seams must be sealed.
Δ
Flexible duct connectors
Use flexible duct connectors to
attach the ducts to the Ecosaire®
unit. Install the flexible duct in
such a way as to prevent mechani-
cal loads from being applied to the
unit, and to prevent unit vibration
from being transmitted to the duct-
work.

Refer to AMCA1guidelines for system effect
considerations.
To prevent unexpected external energy
loss, allow a section of straight duct with a
length five times the blower width leaving
the ECOSaire®. There should be no
elbows, transitions, offsets, duct heaters,
or other flow interruptions closer that 5 X
the width of the blower.
On special order, Dectron may be able to
provide bottom, top, or side discharge blow-
ers. On special order, Dectron may be able to
offer reversed blower rotation.
Some units may have external duct
heaters (by others). To prevent heater fail-
ures and hot spots, locate the heater at
least 5 X the duct width away from the
blower, or any air flow interruptions such as
elbows and transitions.
