3 HIGHLIGHTS COOLSIDE BOX is a close-loop system (direct cooling system) where the air conditioned directly flows into the server-rack. On request is possible to arrange the machine for the cooling system for rows of racks (hot/cold aisle). COOLSIDE BOX is a split system consisting of an outdoor motocondensing unit equipped with inverter driven variable speed compressor and of an indoor evaporating unit supplied together with the server-rack designed to house electronic equipment. COOLSIDE BOX is able to dissipate thermal load from 4 up to 22kW; the modularity of the system together with the logic of adaptive microprocessor control, make this new RCGroup system the best solution for cooling electronic equipment of new generation, characterized by high heat density. COOLSIDE BOX is available in direct expansion (DX) version equipped with an inverter controlled hermetic Twin Rotary or Scroll compressors, which reduces power consumption in real time adjusting to the real plant thermal load. The maintenance of the machines is as simple as possible thanks to the completely removable panels and complete access. PLANT TYPE DIRECT COOLING SYSTEM (CLOSE LOOP) COOLSIDE BOX sucks hot air directly from the rear side of the racks, and, once cooled, enters it in the front side of the rack. Thanks to the "closed" cooling system the electronic equipment contained in racks do not require fans for air circulation. COOLSIDE SERVER RACK UNIT FRONT RC GROUP S.p.A. T_CLSBOX_0113_IT R410A 3

4 ON REQUEST - COOLING SYSTEM FOR ROWS OF RACKS (hot / cold aisle) COOLSIDE BOX units are placed in rows that are arranged so as to obtain alternate cold and hot aisles. Electronic equipments contained in racks independently provide to aspire the necessary air for cooling. - In the hot aisle rack expels the hot air used to cool the electronic components while COOLSIDE BOX draws the hot air to be cooled. - In the cold aisle COOLSIDE BOX blow the filtered and cooled air while the rack draws cold air to cool the electronic components.

5 GENERAL CHARACTERISTICS COOLSIDE BOX: Air conditioned server-racks for direct installation into the room. The machines are made for indoor installation (indoor unit) and outdoor installation (motocondensing unit). The constructive solutions and the internal la lay-out allow high application flexibility and the easy access to the main components for the inspection and routine maintenance. Machines supply fully assembled with refrigerant charge and control systems. The installation requires electrical and hydraulic /refrigerant connections only allowing high costs and time reduction. Final assembly on all machines before shipment including running test, reading and monitoring of operating parameters, alarms simulation and visual check. Design, assembly and test as per the Company Quality Assurance program in full compliance with ISO RC Group has been the first Italian company in its segment to get the ISO 9001 in October 13 th, 1991 with certificate ICIM The machines are in full compliance with European Norms 2006/42CE, 2006/95CE, 2004/108CE, 97/23CE and subsequent amendments.

17 LAN NETWORK AND BMS CONNECTIVITY COOLSIDE BOX + MCAI direct expansion system (mono-split or multi-split system) The LAN network is used to connect external motocondensing unit to their internal evaporating units. It is not possible to carry out the LAN connection to the other system of the plant. Each indoor unit is equipped with terminal having graphic display and keyboard. The external motocondensing unit is not equipped with terminal. All operating parameters are still visible and can be set by each terminal of the indoor units. However, there is a RJ45 socket on the condensing unit's electrical panel for connecting a terminal to the personnel of the service. Hardware interfaces for connection to building management systems (BMS) are optional accessories of the motocondensing unit and are installed in the electrical panel.
