Unit cooler industrial line for high pressure (PS = 50 bar)
Airmax II HP
Application
This new Industrial Line of cubic coolers is specifically
designed for high pressure (PS = 50 bar) in order to be used
with one of the most environmental friendly refrigerant: the
carbon dioxide. Typical use is to keep refrigerated fresh and
frozen goods in medium to very large size of cold rooms. The
range of capacity is quite wide: from 8 to 155 kW at -40°C
with DT=10K.
Through the availability of different fan diameters (up to
800 mm), several fin spacing and a large list of options it is
always possible to fit the best model for the required duty.
With the new frame design and the improved features in the
coil manufacturing, this industrial line allows the clients to
install a reliable model to fit all the needs in the heavy
application of the refrigeration business.
Standard design
Coil
The heat exchanger is designed to offer the best performance
in cooling for the considered application in order
to minimize the refrigerant charge. The coil pitch is 60 x
60, with the tubes in line of 16 mm stainless steel material
and aluminium fins. This new pattern is characterised by a
large heat exchanger surface which ensures longer intervals
between the defrost cycles. The only one inlet and outlet
connection, with the combination of the different large fin
spacing (8, 10 and 12 mm) and the several coil block modules,
make the new line an innovative product range in the
market.
Frame and casing
All units use galvanized steel painted RAL 9002, while the
drip tray is in aluminium painted.
The frame has been design in order to ensure an easy installation
and maintenance. A large and deep drip tray permits
a fast discharge of the water defrosting, with regard to the
bottom storage goods. The supports have two different positions
(flush mounted or space) to consent to install the water
defrost cassette.
Structural parts are fastened with stainless steel bolts and
screws. Structures made of galvanised steel, with optimised
length to permit uniform air suction in the coil.
