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
Versatile
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.
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.
Super Silent
Models & Versions
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.
•Acoustic versions:
- N - basic acoustic configuration;
- SN - low noise acoustic configuration;
•Modules:
- AFW100 (for connection to AST 090-140);
- AFV200 (for connection to GLT/PNP);
- AFV300 (for connection to GLT/PNP);
•Low ambient air temperature - down to -20 °C.
Indipendent
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.

AFV200 & AFV300 can be mounted directly

chiller.
Tailor made Free-Cooling
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.
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.
Total Freecooling Temp. (°C)
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.
