Accessories
Compressors soft starters:: enableÿ the gradual start of compressors by limiting the initial Starting current.
Control system and remote assistance: it allows the assistance and the unit control by
means of web browser, Web server remote connection through corporate network, Tn case
of alarm an alert can be sent via SMS or e-mail. For simultaneous control till 6 or 18 unils.
Capacitor bank for compressor: [lip tools brings the Consumption of the unit to
cosÿ-0,95 by decreasing the absorbed reactive power
Refrigerant gauges: installedon the unit, they show the operative pressures of the cooling
circuit on high and low pressure side.
Shut-off inlet compressor valves: they isolale ihe compressors from the cooling circuit by
anbanning the maintenance operations.
Operating kft up to -2S*C external air temperature: it allows to the chiller to operate
with low external temperatures increasing the working limits. yf
Du-supcrheaters: permits to recover till 25% of condensing hearing for other purposes,
4#Total heat recovery:heat exchanger that allows the condensation heat recovery for others
uses.
Liquid receiver: permits the corned refrigerant supply to ihe thermal expansion valve during external temperature variations.
Continuous capacity control 33-100%: It allows under Ovary condition Ihe unit to respond with the exact load required
granting high efficiency part load performance-www.hoslitoty.if

unit and the exchanger. V
?flow switch: mounted on the exit of the exchanger {user side) detects the water Flow lack
by an alarm to the control System.
Victaullc: hydro connections instead of flanges.
MetaIIk grill: finned coil metal grill for accidental impacts protection,
Special treatment: In Case the units are to be located near the seaside or in aggressive environment we recommend to protect
the exchanger with suitable anti-corrosion treatments:
-Copper finned coils cu/cu- Treated finned coils

Mounted inside the frame permits space saving and easy installation, provided with;
Circulation pump: it gives to the water the pressure head necessary to pass through the hydraulic circuit and reach the terminals.Air bleed valve: it permits to release the air in the plant to obtain optimal thermal exchange.Safety valve: it avoids the working pressure exceeding over the set point.
Storage tank: it serves as thermal flywheel for the plant. Polyurethane insulation minimites the heat losses.

FREE COOLING KIT AIRCOOLEDWATERCHILLERS
Composed by 3 tinned coil with cooper coil 3nd aluminum fins, with servo-controlled 3-way valve. The controller
regulates the valve position by suppling the Free Cooling coil when the climate conditions allow it. The water
conditioning is cooied by the external air decreasing the use of the cooling circuit.
The Compressors start to partiaiize till to stop when the free cooling is active and when the water temperature
coming from the FC coil is dose to the set point-
in this case we got the complete free cooling and the water temperature control comes by means of continuous
regulation of the fans rotation Speed.
in order to optimize spaces, capacity and noise pollution, unit dimensions could be different by the standard model.

FLOWGRID SYSTEM SIAL
Flowgrid stands for efficient noise protection features in cooling, ventilation and air-conditioning technology. This
offers a future-oriented solution for the problem of high-performance technology generating disturbing noise:Flowgrid for axial andcentrifugal fans.The grille cm the air-inlet side drastically reduces the noise emissions and minimises disturbinglow frequency tones.
There are often problems wherever people and technology share space. The movement of air, for example, often
goes hand in hand with noise. With Flowgrid, noise-generating disturbances in the fan inflow are a thingof the past.
The scale of possible energy savings - or efficiency enhancement and noise reduction - that canbe achieved by fittingan optimal diffuser such as the Axitop on 3 conventional heat exchanger is substantial. For example, exchanging a
standard guard grille fan for an axial fan with support grille, guard grille and Axitop diffuser makes savings of up to
27% possible in energy consumption and at the same time up to 7.2 dB(A) less acoustic capacity.
