THINKING ABOUT PRECISION COOLING.....
Applications
FleXaire® units are designed
to meet the demands of
today’s complex & exacting
cooling requirements.
High Technology
Eaton Williams® has over 50
years of experience in the
precision cooling market.
This experience has been fed
into the FleXaire concept, with
critical features fitted as standard.
Controls Philosophy
Computer rooms and data centres require innovative thinking to minimise
the power consumption of the racks, servers and switches being
conditioned. One size does not fit all. FleXaire’s control system and
software has been designed to give customers the ability to customise the
system to their needs. Return air control, supply air control, floor pressure
control, rapid dehumidification, networked units and inhouse BMS
integration are all available. When combined with proven, tried and
tested, energy saving control algorithms, this ensures the ultimate
precision control system.
Space / Size
FleXaire's compact design ensures
manoeuvrability into today’s congested
cooling spaces and once installed
minimises the footprints occupied.
Energy
FleXaire’s design philosophy minimises energy
consumption. This is achieved by combining
energy efficient components as standard, with a
control philosophy that enables the unit to
automatically enact energy saving routines,
without impacting on the conditions within the
controlled space.

CONTROLLER
Advanced Controls Platform
At the heart of the FleXaire® unit is Eaton-Williams® latest purpose-built controls platform.
The 32-bit controller and colour graphical touch screen display offers the very best in reliable,
precision control and intuitive, fully featured user interface design.
Features
• 4.3 inch 480*272 LCD touch screen
• 1GB microSD card storage device
• Integrated RS-485, LON and Ethernet
• Standalone or networked control
• Historic alarm log
• At-a-glance system status views
• Password protected set-point adjustments
• Diagnostic / maintenance mode
• Adaptive control
Scalable, Distributed Control
Comprehensive network control and duty/standby
strategies are integrated into every FleXaire unit.
This ensures that whatever the size of data centre
space, multiple units will operate together to achieve
maximum efficiencies,whilst providing the necessary
levels of reliance.
Internet Enabled
Incorporating an industrial grade TCP/IP
communication suite, the controller can be connected
to an Ethernet LAN or the Internet, and serve real-time
and historic data to standard web browsers.
Integration and Visibility
Furthermore, NMS integration is possible via the
controller’s fully featured SNMP v2c agent.
In addition, in-built FTP and TELNET servers provide
IT system administrators with yet more ways to
remotely monitor and control the environment.
Support for the most common standard BMS
protocols means that the FleXaire can be easily
integrated into various third-party supervisor
systems and BMS.
As standard, the controller supports:
•
MODBUS® RTU
•
MODBUS® IP
•
LonWorks®
•
BACnet® IP (available Q3 2013)

HIGH TECHNOLOGY AS STANDARD
Touch Screen Technology
FleXaire‘s control system is optimised for electronic
cooling. It uses a touch screen display for intuitive
operation, and incorporates full run standby / group
control and remote connectivity as standard.
Connectivity
In today’s complex electronic environments,
connectivity with external systems, for both
monitoring and control input, is essential. FleXaire‘s
control system offers all these features as standard
so that integration can be optimised to suit
customer requirements.
Compact Footprint
FleXaire’s design provides the optimal cooling capacity
from the minimum footprint.This maximises the
available room for electronic racks and provides for
ease of installation.
Blow Through
FleXaire uses a blow through concept to ensure even
airflow, compact footprint and reduced noise levels.
4
EC Fans
EC fans maximise efficiency of air movement and minimise
noise levels. These efficient, backward curved fans are fully
speed controllable as standard, enabling the FleXaire®
controller to automatically adjust the room airflow to its
optimum point. At part load conditions, the EC technology
gives significant energy savings over equivalent AC fans.
Dual Compressors
Dual compressor models incorporate tandem scroll
compressors, maximising control and reducing operating
costs. This is achieved through superior capacity control
and greatly improved part load efficiency, delivering
significant energy savings.
Cooling Technology
FleXaire’s design optimises the cooling cycle and includes the latest
generation of evaporator design. The coil has internal, grooved
copper tubes to maximise refrigerant flow and heat transfer. Special
profile corrugated aluminium fins increase efficiency of heat transfer
and have a phenolic coating. This aids the run-off of any condensate,
and avoids the forming of water droplets to minimise air resistance
through the coil.
High Efficiency Hum / Dehum
As well as controlling the temperature of the air, FleXaire is optimised
to give highly efficient humidity control. In dehumidification mode, the
controller automatically modulates the fan to provide the optimum
level of dehumidification, whilst limiting unnecessary sensible cooling
and reheat. In humidification mode, the controller uses the optional
Vapac® Electrode Boiler Humidifier which modulates its output to
precisely match the room requirements, and has an inbuilt routine
which minimises water consumption.
