General Features

Air-cooled water chiller units for outdoor installation, with axial fans. They are projected to obtain a noiseless, efficient operation and

reliable working, easy to install and of reduced maintenance. All the units are completely factory tested before dispatch.

Technical Features

Frame: Self-supporting gdIvanned steel frame prelected with |jotyesler powder painting SAL 7057PB. Steel strews end bolls.

Compressor* ore situated in A sound prool vane and separated from the air bw-

Compressors: semi hermetic screw, three phase, completed with crankcase heater and internal thermo protection. Lubrication

forced by g£jr pump, Motor starting 'part winding" type or star delta type according to the site. Capacity control 6 steps standard,

continuous from JJ% to 10094optional. They are situated in a sound proof box.

Fans: axial type „ directly coupled to a six or eight pole three phase electric motor.

It allpws an optimal air flow through the finned coil with minimal noise level and power consumption.

Water side heating exchanger : Shell and tube type heat exchanger, made of a carbon steel shell with Uvo independents circuits.

Tubes of copper, screens in brass and linings amianthus free. The exchanger is covered by a dosed cell insulating lining to prevent

tlie formation of condensate ant) the heat exchange with the environment,

Air side heating exchanger: it consists of aluminum finned colls ant) copper tubes with large heat exchanger surface; directlydesigned by Frost Italy, allows the maximum efficiency with minimal amount of Space.

Refrigerant circuit: made of pickled copper, it includes lamination device, dehydrator filter, high and Tow pressure switches, sightglass, liquid line solenoid valve and shut off faucet, security valve and service connections,

Electronic expansion valve: for the condensed refrigerant rolling, in comparison with the thermostatic valve it enables fastresponse time according to the load variation by enhancing the unit performances.

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

COMPLETE HYDRAULIC KIT

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.
