AquaFree
Add-on Freecooling modules for Aries tech, Galaxy tech and Phoenix plus, transforming
the Chiller into an all-in-one modular and expandable Freecooling Chiller.
Cooling capacity 242 – 466 kW per single module.
PLUG & PLAY
PEACE OF MIND
Connect AquaFree to the chiller (AST, GLT and PNP) and
set the software parameters comunications between the
units. The chiller’s xDRIVE microprocessor will control the
chiller / free-cooler combination as a single unit. In case of
AQUAfree connection to a chiller previously installed check
before the software compability. The AQUAfree / chiller
piping kit is available on request.
Each AquaFree module features its own microprocessor,
allowing it to operate independently. If one module suffers a
fault the others can still operate, if the chiller suffers a fault
the modules can continue to operate. AquaFree can operate
at ambient temperatures of -15 °C to +46 °C. Each AquaFree
module features independent aeraulic sections featuring
axial fans with progressive activation (continuos control on
request).
ENERGY EFFICIENT
AquaFree can easily obtain savings of 30% or more, offering
efficiency levels well beyond the industry norm. The
modular design permits additional AquaFree modules to
be added, allowing efficiencies to be further increased and
tailored to individual applications.
SUPER SILENT
Choose between 2 noise levels, both extremely quiet, with
an electronic fan speed control option to further reduce
part load noise levels. Especially during night time, when
temperatures drop and freecooling becomes more active,
AquaFree’s low noise becomes a notable asset.
INDEPENDENT
Each module features its own electrical connection and 3-way
valve, as well as its own electrical panel and microprocessor
with independent alarms and water in/out and ambient
temperature visualization: consequently each module can
operate completely autonomously.
GLYCOL FREE KIT
The glycol free kit is available on request and is ideal in
applications requiring an absence of glycol, such as food
industries. The glycol free kit, which features its own
intermediate exchanger and hydraulic circuit, is simply
installed between the chiller and the AquaFree modules.
VERSATILE
As AquaFree modules are independent, so system
transportation is simplified. AquaFree can be positioned
separately if space needs dictate it. It is also possible to install
AquaFree, or add additional modules, at a later date. Each
AquaFree module features its own remote on/off control.

TAILOR MADE FREECOOLING
SELECT YOUR EFFICIENCY
AquaFree allows the user to define the desired efficiency,
simply combining multiple modules to achieve the
optimum freecooling level. Any combination of AFV200
and AFV300 modules allows the freecooling section to
be increased one “V” coil at a time from a minimum of
two coils upwards.
As an example, a GLT150N chiller, operating at water
15/10 °C with 30% glycol and a single AFV300 module
(Basic "N" configuration), achieves a TFT (total freecooling
temperature), the temperature at which the unit achieves
100% freecooling) of -0,2 °C). Alternatively, the application
of two AFV200 modules (Efficient "E" configuration) achieves
a TFT of +3,1 °C. By applying an AFV300 module and an
AFV200 module (High efficiency "HE" configuration), a TFT
of +5,0 °C can be achieved.
The size and number of AquaFree modules applied allows
the efficiency level to be progressively increased from Basic
(N) to Efficient (E) and even High efficiency (HE) levels.
The integral microprocessor allows AquaFree to
operate independently.

The standardised ESEER indice establish the average weighted efficiency of a chiller and provide insight – in a more accurate manner than the EER value – into the relationship
between the useful effect (energy removed from the rooms) and the energy expended (electrical power consumption) of an air conditioning unit throughout an entire season of
operation.
The graphs show the importance of operation at partial load from the energy standpoint; specifically, in the interval of 50-75% of rated capacity the unit develops significantly
70-80% of the useful effect, i.e. the cooling energy produced.

CLICK AND CHECK
xCONNECT, MTA’s world of connectivity solutions, allows
connection to User-supplied Building Management Systems
(BMS), connection via local LAN or Ethernet networks,
connection to MTA’s dedicated xWEB supervisor, the possibility
to program or download storical data via USB connection, and
much more beyond.
Serial connection to the most advanced BMS systems allows
MTA units to be integrated into a centralised supervisor
through ModBus protocol. The integration with Lonworks,
Bacnet, Profibus system is possible through apposite gateways
(not included).
Local supervision via intranet or internet can also be achieved
via Ethernet, with pre-programmed HTML supervision pages
which, according to the unit type, are already pre-programmed
within the unit itself.
Local Ethernet connection allows multiple units to be
interconnected within an autonomous system, with one unit
acting as Master. The User can manage all units within the
system via the Master unit, or via a remote User interface.
MTA’s xWEB function represents one of the most advanced
supervision systems currently available, and integrates the
latest internet applications.
All xWEB solutions feature a server utilising a µc-Linux
operating system, allowing data transmission to a client PC.
The server reads, files and manages all information arriving
from the units to which it is connected. The following
functions are offered in Web page format, either locally or
remotely, even via GPRS:
• Dynamic multiparameter visualization, either graphically or
numerically, of all analogue data, the outputs status and the
alarm status;
• Remote modification of the operating parameters;
• Graphic scheduling for command functions;
• System personalization, including alarm messaging rules;
• Alarm reset procedures and alarm history filing by remote
display;
• Alarm message transmission via fax, sms and e-mail (only
for xWEB with built in GPRS modem).
Features offered depend upon unit type and xCONNECT configuration utilised.
