GENERAL INFORMATION
DB-Aire units are precision environmental
control systems that bring a new standard of
flexibility and reliable performance to the
computer room. Because room requirements
differ, DB-Aire offers a wide range of sizes
and styles.
DB-TEMP SYSTEMS
7, 11, 14 and 18 kW (2, 3, 4, and 5 ton)
nominal capacities in air-cooled, water/glycol
cooled, or chilled water models.
25, 32, 39 and 46 kW (7, 9, 11, and 13 ton)

models.
Chilled water models in 25 through 106 kW
(7 through 30 ton) nominal capacities.
COMPUTER COMFORT
Computer rooms require air which is clean
and properly distributed with precisely
controlled temperatures and humidity.
Building HVAC systems simply are not
designed to meet these demands. But, DBAire units easily accomplish these goals with
top-rated efficiency, 24 hours per day 7 days
a week! DB-Aire units have been designed to
meet the demanding requirements of the most
advanced computer room.
Although building HVAC systems cool your
staff, they fall short of your computer's comfort
need. And they are unable to provide the
close humidity control required in a modern
data processing centre.
DESIGN FEATURES
Each unit is a complete environmental control
system, factory wired, tested, and specifically
designed to provide temperature, humidity,
and dust control for computer room or telecommunications installations.
A specially designed compact tubular steel
frame allows for a minimum space
requirement in your computer room for both
upflow and downflow units while still providing
excellent serviceability. All parts are easily
accessible.
The DB-Processor, a microprocessor based
control displays temperature and humidity on
liquid crystal display (LCD). A comprehensive
diagnostic routine is standard.
HIGH PERFORMANCE LOW COST
DB-Aire’s high-tech, furniture look is clue to its
high performance but belies its more than
competitive price. Every DB-Aire unit comes
with a commitment to excellence as standard
equipment.

DB-AIRE MONITORING/ CONTROL
The heart of the Environmental Control System
is the microprocessor based DB-Alarm
Proccessor. The liquid crystal display not only
monitors your data center's temperature,
humidity, airflow, and cleanliness, but also
provides component run times, alarm history
and an automatic self-test of the microprocessor
on system start-up. Multiple messages will be
displayed by automatically scrolling from each
message to the next. All of these messages are
spelled out in English language on the liquid
crystal display (LCD). The LCD has 20
characters on 4 rows, high density and backlit.
Multiple alarms will be displayed sequentially in
order of occurrence.

DB-AIRE MONITORING/ CONTROL
DB PROCESSOR
COMMUNICATION INTERFACES
(Optional)
The DB series of controllers are LonWorks®
compatible, using a special serial board.
Electrical supported standards: RS485 and
FTT10.
Below are the available communication interface
features of the DB-Alarm processor:
BMS interface
The DB controllers
can be connected to
the BMS in the
following ways:
Ø Directly, without
using a gateway,
thanks to the ability of the DB series
controllers to select the protocol used,
Ø Using a gateway that converts the DB
proprietary protocol used by the BMS,
Ø Integrating the driver for the management of
the DB proprietary protocol into the BMS.
The following protocol are used by the DB
controllers to ensure connectability to the other
systems:
This is the protocol designated in 1995 by
ASHRAE (American Society of Heating,
Refrigerating and Air-Conditioning Engineers)
as the organisation’s official protocol.
DB provides a gateway through which all DB
controllers can interface to BACnet™ systems.
Type of supported protocol: BACnet™, PointTo-Point and RS232 communication standard.
THIRD PARTY PROTOCOLS
DB controllers can provide numerous gateways
for interfacing its controls to proprietary
supervisory systems.
Modbus®
Introduced in the 1970s and now one of the
most widely-used BMS protocols.
The DB series controllers can communicate
directly in Modbus protocol®.
Like all DB controllers, it can also be connected
to a Modbus® system using a gateway.
Type of supported protocol: Modbus® slave,
RTU mode; RS485 and RS232 communication
standard.
Trend is a building Automation System very
widespread in the Anglo-Saxon countries and in
general in Europe.
The DB-Aire controller is TREND compatible,
through the proper serial card. TREND deals
with the configuration and the supply of the
interface card. Trend can be contacted directly
on Tel. +44(0)1403211888.
SNMP
With millions of devices
installed world-wide, the
LonWorks®
system
developed by Echelon®,
is one of the dominant
solutions on the market
for the automation and control of industries,
offices, homes and transport.
SNMP (Simple Network Management Protocol)
is a protocol for the management of TCP/IP
networks (the Internet protocol), established in
1988 based on the specifications of the IAB
(Internet Administration Board), the body that
supervises the internet protocol.
All DB controllers can be connected to a 10
Mbps Ethernet™ network via gateway or
PlanVisor, and communicate with systems that
use the SNMP Protocol.
DB-AIRE MONITORING/ CONTROL
Metasys®
is
the
building
automation system developed by
Johnson Controls.
Johnson itself handles the
implementation of the software to control the
interfaced devices into its system.
TCP/IP Gateway
Thanks to this gateway with “WEB server”
capability, all DB-Aire units can now be
connected to a 10Mbps Ethernet™ local
network.
The following functions are therefore possible:
DB-Aire
can
provide
developers
and
system
integrators
with
DLLs
(Dynamic link Libraries) for 16and
32-bit
Windows ®
applications.
Technically, a DLL is a compiled file that
contains a series of functions for use by any
other server process. In particular, the DB-Aire
DLLs contain the software routines that allow
the integration of communication with all DBAire instruments into the application, without
needing to know the used protocol.
Direct modem
All
the
DB-Aire
controllers can be
connected directly to
a traditional or GSM
modem.
They can thus be controlled directly by remote
stations, without requiring the use of a gateway
or intermediate system.
Ø Display the parameters and the data from the
controller using an Internet browser on any
PC connected to the local network or Internet
Ø Send the data to a supervisor PC connected
to the network that is able to handle the
SNMP protocol.
SMS, short message service
Dunham-Bush has payed great attention to
fitting the DB controllers with the ability to
communicate important information directly by
SMS message.
In fact, this is the best communication system
for sending data wherever and promptly.
By simply connecting a GSM modem, the DB
series controllers can not only send alarms and
information, but also receive commands via
SMS that service personnel can use to reset
any alarm or perform the necessary operations,
without having to travel to the installation.
NETWORK MONITORING (OPTIONAL)
NETWATCH
For smaller systems with
the same management
and control requirements
as larger installations,
NetWatch offers the
complete and integrated
solution for all monitoring
and remote management needs. NetWatch, a
versatile data recorder for the controllers
connected in a supervisory network, is also:
Ø an excellent monitoring system. In the event
of alarms, it can send faxes, SMS messages,
call a remote security center, etc.,
Ø an exceptional instrument for remote control.
Using a traditional or GSM modem, it can
display and modify all of the parameters in the
system. Optional 110V or 230V 50/60Hz.
NetVisor
This is the latest generation “WEB based”
supervisory software. It allows refrigeration and
air-conditioning systems to be monitored and
controlled using a simple Internet browser: the
pages displayed on the PC are in HTML format,
the language of the worldwide web. NetVisor is
designed to communicate externally with more
than one protocol.
DB-TEMP DESIGN FEATURES
DB-TEMP MODELS

WATER/GLYCOL COOLED
FRAME AND CABINET
The heliarc welded steel frame provides for
maximum strength and ease of access. Side
and front panels can be easily opened and
removed with quarter-turn fasteners allowing full
access to all unit components. All panels include
25mm (1 inch) thick, 1-1/2 lb density insulation
for protection and sound attenuation. DB-Aire's
unique frame design allows for your selection of
either downflow or upflow air patterns in the
same compact dimensions.
COIL SECTION
Designed for draw through application with large
face areas for low velocity air to reduce
turbulence and provide greater efficiency in the
cooling and dehumidification process.
FAN SECTION
The centrifugal forward-curved, double-width,
double-inlet blower configuration is engineered
for quiet, reliable operation. The blowers are
AMCA certified and factory certified dynamically
balanced. The draw through design insures
even air distribution across the coil, low internal
cabinet pressure losses, and static sealing of
the filter section. The fan motor is totally
enclosed and is mounted on an adjustable slide
base.
reheat coils provide ample capacity to maintain
room dry bulb conditions during a system call for
dehumidification. Three equal stages give a
more accurate controlled response to the
requirements of the computer room. The heating
elements are protected by thermal safety
switches. The three stages of reheat create a
noticeable lowering of energy use.
HUMIDIFICATION (OPTIONAL)
The disposable cartridge electric stream
generator humidifier provides humidification
down stream of the cooling coil. The humidifier
is designed to allow all units at any voltage to
produce full rated steam output at an optimum
low water level.
DB-AIRE UMID
INTERFACE
The DB-Aire Umid
interface allows the
control of humidifiers
directly from the DBAire microprocessor
controller.
Steam Generator Humidifier
FILTERS
Computer room air cleanliness is enhanced by
standard 50 mm (2 inch) deep pleated 30
percent efficient filters (based on ASHRAE 5276) which can be easily changed by opening the
front panel for the 2-5 tons models. The DBTemp 7-13 tons models use standard 100 mm
(4 inch) deep pleated 30 percent efficient filters
(based on ASHRAE 52-76)
ELECTRICAL REHEAT
The three stage stainless steel finned tubular
COMPRESSORIZED SYSTEM
The single stage refrigeration circuit includes a
high efficiency and quiet scroll compressor. The
scroll compressor has a high EER, low
DB-TEMP DESIGN FEATURES
sound power level and is highly reliable. The
high efficiency is due to the controlled orbit with
floating seals and advanced scroll geometry
design. There is no contact of the mechanical
parts in the scroll design which eliminates
mechanical wear and tear. The motor is 100%
cooled by suction gas. A check valve is located
directly above the fixed scroll discharge port.
This prevents the compressor from running
backwards after the power has been switched
off (i.e. no rattling and no shutdown noises). The
motor is fitted with an internal thermal overload
protection against maximum operating overload
and loss of refrigerant charge. The refrigeration
circuit includes filter drier, sight glass, adjustable
expansion valve, low pressure override timer,
manual reset high pressure control, short-cycle
timer and rotalock service valves.
Air Cooled Systems- A wide range of sizes of
remote mounted air-cooled condensers are
available from DB-Aire in vertical discharge.
Condensers are manufactured by DB-Aire and
include circuits sized to match the heat rejection
of the corresponding compressor in the DB-
Temp. The industrial duty design includes
galvanized corrosion resistant housings, high
efficiency aluminium finned (optional copper fins
available) copper tube coils; coated fan guard;
energy efficient thermally protected motors
integral factory wired and tested control panel.
Water/Glycol Cooled System - Includes unit
mounted condensers for providing the required
capacity for heat rejection with minimum
water/glycol flow and low total pressure drop.
Dry-Air Cooler For Glycol Systems - A wide
range of sizes of remote mounted dry-air
coolers are available from DB-Aire in vertical
discharge and direct drive. Dry-air coolers are
manufactured by DB-Aire and are sized to
match the heat rejection of the corresponding
DB-Temp unit. The industrial duty design

FRAME AND CABINET
The heliarc welded tubular steel frame provides
for maximum strength and ease of access. Side
and front panels can be easily opened and
removed with quarter-turn fasteners allowing full
access to all unit components. All panels include
25 mm (1 inch) thick 1-1/2lb density insulation
for protection and sound attenuation. DB-Aire's
unique frame design allows for your selection of
either downflow or upflow air patterns in the
same compact dimensions.
A-FRAME COIL
Computer selected coil design, using interwoven
coil surface increases unit efficiency at low
loads. Air is drawn through both circuits of the
coil at low velocity providing effective surface
exposure with minimum turbulence. This
provides greater efficiency in the cooling and
dehumidification process.
FAN SECTION
The 381 mm (15 inch) diameter, centrifugal,
forward-curved,
double-width,
double-inlet
blower configuration is engineered for quiet,
reliable operation. The blowers are AMCA
certified and factory certified dynamically
balanced. The draw through design ensures
even air distribution across the A-frame coil. The
draw through design also ensures low internal
cabinet pressure losses, and static sealing of
the filter section. Fan motors are totally
enclosed and mounted on an adjustable slide
base.
FILTERS
Computer room air cleanliness is enhanced by
standard 100 mm (4 inch) deep pleated 30
percent efficient filters (based on ASHRAE 5276) which can be easily changed through either
side of the unit. Upflow units are changed from
right hand side.
ELECTRICAL REHEAT
The three stage stainless steel finned tubular
reheat coils provide ample capacity to maintain
room dry bulb conditions during a system call for
dehumidification. Three equal stages give a
more accurate controlled response to the
requirements of the computer room. The heating
elements are protected by thermal safety
switches. The three stages of reheat create a
noticeable lowering of energy use.
HUMIDIFICATION (OPTIONAL)
The disposable cartridge electric stream
generator humidifier provides humidification
down stream of the cooling coil. The humidifier
is designed to allow all units at any voltage to
produce full rated steam output at an optimum
low water level.
DB-AIRE UMID
INTERFACE
The DB-Aire Umid
interface allows the
control of humidifiers
directly from the DBAire microprocessor
controller.

DB-AIRE DESIGN FEATURES
COMPRESSORIZED SYSTEMS
The refrigeration system uses two(2) highly
efficient and quiet scroll compressors. The scroll
compressor has a high EER, low sound power
level and is highly reliable. The high efficiency is
due to the controlled orbit with floating seals and
advanced scroll geometry design. There is no
contact of the mechanical parts in the scroll
design which eliminates mechanical wear and
tear. The motor is 100% cooled by suction gas.
A check value is located directly above the fixed
scroll discharge port. This prevents the
compressor from running backwards after the
power has been switched off (i.e. no rattling and
no shut-down noise). The motor is fitted with a
thermostat which protects the compressor if a
malfunction occurs. The refrigeration circuit
includes built in compressor overload protection,
filter drier, sight glass, adjustable expansion
valve, low pressure override timer, manual reset
high pressure control, short-cycle timer and
rotalock service valves.
Air Cooled Systems - A wide range of sizes of
remote mounted air cooled condensers are
available from DB-Aire in vertical discharge.
Condensers are manufactured by DB-Aire and
include circuits sized to match the heat rejection
of the corresponding compressors. The
industrial duty design includes galvanised
corrosion resistant housings, high efficiency
aluminium finned (optional copper fins
available), copper tube coils; coated fan guards,
energy efficient thermally protected motors; and
integral factory wired and tested control panel.
Water/Glycol Cooled Systems - Include unit
mounted condensers for providing the required
capacity for heat rejection with minimum
water/glycol flow and low total pressure drop.
Dry-Air Cooler For Glycol Systems - A wide
range of sizes of remote mounted fluid coolers
are available from DB-Aire in vertical discharge.
Dry-air coolers are manufactured by DB-Aire
and are sized to match the heat rejection of the
corresponding unit. The industrial duty design
includes
galvanised
corrosion
resistant
housings, high efficiency aluminium finned
(optional copper fins available), copper tube
coils; coated fan guards; energy efficient,
thermally protected motors and fan cycling
controls with integral factory wired and tested
control panel.

CHILLED WATER DESIGN FEATURES
DB-TEMP MODELS
DB-AIRE MODELS
FRAME AND CABINET
The heliarc welded structural steel frame
provides for maximum strength and ease of
access. Side and front panels can be easily
opened and removed with quarter-turn fasteners
allowing full access to all unit components. All
panels include 25 mm (1 inch) thick 1 1/2 lb
density insulation for protection and sound
attenuation. DB-Aire's unique frame design
allows for your selection of either downflow or
upflow air patterns in the same compact
dimensions.
COIL SECTION
The coil is designed for draw through application
with large face areas for low velocity to reduce
turbulence and provide greater efficiency in the
cooling and dehumidification process. The
chilled water flow is controlled by a three-way
modulating mixing valve for accurate and
economical temperature and dehumidification
control.
FAN SECTION
The 380mm (15 inch) diameter, centrifugal
forward-curved,
double-width,
double-inlet
blower configuration is engineered for quiet,
reliable operation. The blowers are AMCA
certified and factory certified dynamically
balanced. All DB-Aire models have a two belt
drive system to assure reliability should one belt
fail. The draw through design ensures even air
distribution across the chilled water coil. It also
ensures low internal cabinet pressure losses,
and static sealing of the filter section. The fan
motor is totally enclosed and is mounted on an
adjustable slide base.
FILTERS
Computer room air cleanliness is enhanced by
pleated 30 percent efficient filters (based on
ASHRAE 52-76). Standard DB-Aire filters are
100mm (4 inch) deep, and may be changed
through the side of the unit. DB Temp filters are
50mm (2 inch) deep and are changed by
opening the front panel.
ELECTRICAL REHEAT
The three stage stainless steel finned tubular
reheat coils provide ample capacity to maintain
room dry bulb conditions during a system call for
dehumidification. Three equal stages give a
more accurate controlled response to the
requirements of the computer room. The heating
elements are protected by thermal safety
switches. The three stages of reheat create a
noticeable lowering of energy use.
HUMIDIFICATION (OPTIONAL)
The disposable cartridge electric stream
generator humidifier provides humidification
down stream of the cooling coil. The humidifier
is designed to allow all units at any voltage to
produce full rated steam output at an optimum
low water level.
DB-AIRE UMID
INTERFACE
The DB-Aire Umid
interface allows the
control of humidifiers
directly from the DBAire microprocessor
controller.
