FLEX SERIES The pateted series of modular packaged chiller ad heat pump with scroll compressors ad R-40A refrigerat orieted towards higher eergy efficiecy ad low oise emissios. MODULAR Due to the multiple cofiguratio available, Flex Series is suitable for air coditioig ay eviromet. More tha 00 compositios are possible ad the power rage ca be icreased over time i a simple ad ecoomical way, thus followig the developmet of the projects. ECOLOGICAL The ecological refrigerat gas R-40A is ot dagerous for the ozoe; it allows high efficiecy systems (ODP = 0) ad coveiet electrical cosumptio, ad therefore, lower emissios of CO i the atmosphere. The scroll compressor, optimized for R40A are more efficiety, compact ad silet. EFFICIENT The uit assure coefficiets ESEER ad IPLV extremely high ad a perfect cotiuous respose to the istallatio load variatio. FLEX SERIES sigle circuit uits operatig with R40A are characterized by a ESEER clearly superior to the traditioal dual-circuit uits operatig with R407C. SILENT Due to the special axial fas with owlet or Hy Blade profile of the shovels, Flex Series is more silet: it reaches a oise reductio of 6 db(a) compared to stadard axial fas versio. RELIABLY EVEN IN EXTREME CONDITIONS Flex Series uits ca be equipped with low outdoor ambiet kit: up to -0 C PATENTED Flex Series is covered by iteratioal patets: Exteral Air Recover I heat pump mode it allows free heatig of exteral air, avoidig the use of a exteral heat recovery with a icrease of 40% for the COP.

PERSONALIZATION ON INDUSTRIAL SCALE Medium ad high powered coolig uits have always bee built o order, each time persoalized accordig to the cliet requiremets. Thaks to Flex Series, Trae itroduces the big mass productio ito this sector, without reoucig the flexibility obtaied thaks to a more persoalized productio, o the cotrary eforcig it thaks to the cocept of modularity. HIGH ENERGETIC EFFICIENCY All basic modules are fitted out with twied scroll compressors i order to assure costatly very high classes of eergetic efficiecy ad seasoal eergetic idexes (ESEER ad IPLV). This allows to perfectly ad quickly follow system load variatios. Moreover, the Hybrid Smart Coolig eables to icrease to 40% the eergetic efficiecy. HYBRID SMART COOLING, A NEW LOGIC TO CHOOSE A COOLING UNIT The choice is t aymore at 5 C, but at a lower temperature, as for istace at 0 C. It s from this temperature o that Hybrid Smart Coolig works ad the coolig uit is able to exactly satisfy the system power demad. Hybrid Smart Coolig is the oly system i the world which allows to reduce cosumptio of eergy ad meawhile to reduce the iitial ivestmet costs. Hybrid Smart Coolig uses water. Ayway cosumptios are extremely low. If outdoor temperature is up to a 0 C there is o cosumptio, at 5 C the water cosumptio is equal to 7 litres/hour for each coolig kwh produced, icreasig to 0 litres/hour for each kwh whe the outdoor temperature raises to 45 C. The water requiremets ca be compared to a evaporative tower (about 7/litres/h kwh) but it is just ecessary whe the air temperature is higher tha 0 C. PARTIAL LOAD HIGH EFFICIENCY THANKS TO THE HUGE NUMBER OF CHOKING STEPS Thaks to the combiatio of multiple machies it is possible to icrease efficiecies at partial loads. For the sizes equipped with two compressors of differet power, it is possibile to obtai capacity steps. This icreases partial load efficiecy ad the seasoal average efficiecies of the idividual machie ad the system of machies.

ELECTRONICS FOR MODULAR APPLICATIONS Flex Series, for the modular istallatios, is equipped with the most iovative cotrol system: Trae applies the most recet hardware techology available o the market ad has developed its ow cotrol software, properly implemeted for this product lie, with the purpose to maximize efficiecy ad performaces. 6 bit microprocessors with a MB storage capacity, real time clock i order to have a alarm archive, multiligual cotrol software. Coceived to be iserted ito a local etwork of electroic cards for the coordiated maagemet of may coolig circuits o the basis of a sigle power regulatio probe, with diversified cotrol ad alarm sigals of codesatio which just stop their circuit istead of the whole etwork. The card addressed as master calls the power steps allotted o the whole system ad maages the geeral alarms. The slave cards maage their ow compressors accordig to the timig suggested by the master oe, to codesatio ad to their circuit alarms. It is possible to maage each sigle etwork card by meas of a uique 6 buttos termial with LCD graphical display; to set the device power regulatio setpoit; to moitor the aalogical variables of the system status (i/out water temperatures, pressure o each circuit); to moitor the actuators status o each circuit (o/off compressors, atifreeze resistaces, etc.); to read text ad code of the iterveed alarm; to switch o/off the uit ad to chage the fuctioig cycle; to modify the fuctioig parameters of the device by meas of the iput of a password: proportioal callig bad of power steps, o/off compressors timig, defrostig timig (for heat pumps), itervetio threshold of atifreeze protectio, possible regulatio curve of fas speed depedig o the codesatio pressure, pre-startig timig ad post switchig off of the water circulatio pump. There are three types of alarms: SERIOUS ALARMS: maaged by a master card, they have as cosequece the deactivatio of the whole system, warig o the display, alarm buzzer, relay exit activatio of the geeral alarm (mail o the master card). They are: lack of water flow; possible warig of serious alarm o digital iput (lack/iversio of the triad of power supply voltages of the machie, curret leakage to groud). CIRCUIT ALARMS: they deactivate oly the circuit where they have occurred, give a text alarm o the display, activate the buzzer ad the geeral alarm output relay fitted o the master card. They are: high/low pressure; compressor thermal protectio; fas thermal protectio; temperature or pressure probe failure; SIGNAL-ONLY ALARMS: they oly give a sigal text o the display ad activate the geeral alarm output relay fitted o the master card, but they do't deactivate ay circuit of the machie. They are: uit maiteace time; compressor maiteace time; water pump maiteace time; et self-cotrol failure: for the multi-card coolig uits, this meas that oe ore more slave-addressed cards are off-lie.
