External panels in pre-clad sheet steel(simil-Peraluman) and structure in galvanised steel with paint finish. Therange includes the single-circuit two-compressor versions and t10 dB(Acircuit four-compressor versions.- The unit is supplied fully refrigerant charged and factory tested. On site
installation only requires power and hydraulic connection.
2.3 StructureFrame in polyester-painted galvanized steel.The self-supporting frame is built to guarantee maximum accessibility forservicing and maintenance operations.
2.4 Panelling2 compressor units: the external paneling, from pre-clad sheet steeloffers maximum ease of access to the internal components.A 30 mm thick fiberform soundproofing insulation on the compressors section is available as an accessory and ensueres a noise reductionof 4 dB(A).4 compressor units: the chiller is provided without paneling. The paneling,with a 30 mm thick fiberform soundproofing insulation, is available as an accessory and ensueres a noise reduction of 10 dB(A).
2.5 CompressorHermetic scroll compressors in tandem layout complete with oil sumpheater, electronic overheating protection with centralised manual resetand a two-pole electric motor.
2.6 Plant side heat exchangerBraze welded AISI 316 steel plate heat exchanger. The heat exchangersare lined on the outside with closed-cell neoprene lagging. When the unitis not operating, these are protected against formation of ice on the insideby an electric heater with thermostat, while when the unit is operatingprotection is ensured by a differential pressure switch on the water side.The unit can also operate with non-freezing mixes, down to heatexchanger outlet temperatures of -8°C.
2.8 Refrigerant circuitMain components of the cooling circuit:- single circuit in tandem compressors- R410A refrigerant- plate heat exchanger- drier filter with replaceable cartridge- refrigerant line sight glass with humidity indicator- mechanical thermostatic expansion valves- high and low pressure transducers- high and low pressure safety valve- safety switching device for limiting the pressure- crankcase heater on each compressor

Chiller Plant Control with Active Optimization System
ClimaPRO System Manager
ClimaPRO System Manager represents the state-of-the-art platform for chiller plant management and control.ClimaPRO ensures to actively optimize the entire chiller plant by managing and adjusting each component directly involved in the production and the distribution of the heating and the cooling energies, therefore involving chillers and heat pumps, pumping groups as well as the source-side devices like, for example, the cooling towers.
In particular, ClimaPRO measures in real-time all the operating variables from the fi eld, for each individual device and each of the main system branche, by using serial communication lines as well as dedicated analogue signals.
The acquired data are then compared with the design data of each single unit at any different working conditions, thus allowing to implement control strategies based on dynamic algorithms which take into account the real operating conditions.
On the basis of these values, an advanced diagnostic module also allows to assess the level of effi ciency for each individual unit, translating data into easy-to-read information in order to simplify and optimize the maintenance activities.
The “Chart Builder” software module allows to display the trends of the main operating variables. The “Reporting” module allows to send reports to selected users, including data and system’s status of the main devices as well as to perform calculation of the energy indexes for each single unit and for the entire chiller plant.
The accessibility to ClimaPRO System Manager is ensured by an integrated web server that makes it visible from any computer equipped with a web browser, either locally or remotely.

Given the typical operating conditions of units designed for indoor installation, which can be associated (according to reference document IEC 60721) to the following classes:- climatic conditions class AA4: air temperature range from 5 up to 42°C (*)- special climatic conditions negligible- presence of water class AD2: possibility of water dripping inside the technical room- biological conditions class 4B1 and 4C2: negligible presence of corrosive and polluting substances- mechanically active substances class 4S2: locations in areas with sand or dust sources
The required protection level for safe operation, according to reference document IEC 60529, is IP21 BW (protection against access of external devices with diameter larger than 12 mm andwater falling vertically).The unit can be considered IP21 CW protected, thus fulfilling the above operating conditions.
