REPLACE: BT0F009GB-04 The ELFOENERGY series chillers represent an important stage in the development of this type of unit. They feature the most up-to-date advances in technology, standing out for: EFFICIENCY thanks to its special construction, the ELFOENERGY ensures high energy efficiency, in particular during operation at partial loads; SELF-ADAPTING the evolved electronics implemented adapt the operating parameters of the chiller to the load conditions of the system it is installed in, optimising consumption, efficiency and the working life of the components; EASE OF INSTALLATION each unit is supplied as standard with a complete hydronic assembly and is completely tested in the factory; installation is consequently quick and easy. BT0F009GB-05 Clivet is partecipating in the EUROVENT Certification Programme "Liquid Chilling Packages". Products are listed in the EUROVENT Directory of Certified Products and in the site www.eurovent-certification.com. Eurovent Chillers Certification Programme covers air cooled packaged chillers up to 600 kw and water cooled packaged chillers up to 1500 kw. CERTIFIED QUALITY SYSTEM UNI EN ISO 9001:200

Percentage of operating time BT0F009GB-05 Load requested to the unit COMFORT IS A HUMAN RIGHT. CARE FOR THE ENVIRONMENT IS A HUMAN DUTY. The ELFOENERGY is an appliance of new conception, designed especially to operate with increasing efficiency as thermal load reduces, yet able to handle the maximum load demand whenever necessary. Because of significant diurnal and seasonal variations in load, chillers must operate for prolonged periods under partial load conditions. A ELFOENERGY unit always ensures conditions of maximum comfort coupled with ultra high efficiency for most of the system s working life, which means a big saving in electrical energy. This reflects the corporate policy of CLIVET, namely: offering fundamental and concrete solutions to help safeguard the well -being of people and their environment. By way of example, here is a seasonal thermal load graph relating to a multi-use building (shops, offices and apartments) located in the Milan area. SEASONAL THERMAL LOAD March April May June July August September October MULTIPLE HIGH EFFICIENCY SCROLL COMPRESSORS IN THE SAME COOLING CIRCUIT compressor Single coil A key aspect of the approach adopted in designing the ELFOENERGY is the notion of equipping a single cooling circuit with a battery of SCROLL compressors, rather than the conventional separated circuit. Moreover the use of compressors with different capacities allows a rise of the capacity step number and in this way a better capacity-control flexibility. This enables the unit to adapt perfectly to the system load. The evolved control equipment used with ELFOENERGY units will optimize the activation sequence and balance the operating cycles of the compressors to maximum advantage compressor Evaporator EUROVENT ENERGY EFFICIENCY CLASSIFICATON CLASS A IN HEATING MODE ELFOENERGY XEE units have been studied to obtain the highest ENERGY EFFICIENCY also in full load condition. For the heating operation, the ELFOENERGY R-4A is in Eurovent energy efficiency classification class "A" A CLASS HIGH EFFICIENCY AT PARTIAL LOADS The unit in an air-conditioning system is selected on the basis of the maximum load the system is designed to handle. In practice however, maximum load conditions account only for a small percentage of the overall operating time, whereas the partial load operation is the true condition in which the unit had to operate. Simulation tests conducted in different buildings have shown that systems operate on average for 90% of total operating time with thermal load lower than 60%. Accordingly, operating efficiency under partial load conditions is a key consideration when selecting a chiller. For 60% of the time, load is less than 0% For 90% of the time, load is less than 60% 2 Load percentage

Electrical energy (kwh) ELFOEnergy - medium EER EER monthly comparison Standard Unit - medium EER The electronic controller and the specific constructional configuration highlight the thermodynamic efficiency of ELFOENERGY. To achieve maximum efficiency, the electronic controller starts the compressors according to the most favourable ratio between the exchange surfaces, so that the condensing and evaporation temperature are always the most advantageous. The diagram to the side shows the trend in efficiency (EER) of an ELFOENERGY unit and of a traditional unit on a typical summer day. It is clear how the efficiency of the ELFOENERGY is practically always higher, reaching values that are even more than twice as high at some times of the day, when the load thermal is lower. October September August July June May April March LOW OPERATING COSTS Thanks to the characteristics described previously, ELFOEnergy ensures much higher efficiency than a traditional chiller for most of the operating time. Comparing, in the same system, the power consumption of the ELFOENERGY against the power consumption of a traditional chiller with the same capacity, the seasonal savings can reach around 5%. These data, combined with the intrinsic reliability of the unit, make the ELFOENERGY an essential option in both terms of pay back time and peace of mind. Electrical energy weekly consumptions (for a office building in Milan) Traditional unit March April May June July August September October In a system with a 4 kw unit installed, the annual energy saving obtained with a ELFOENERGY is in the region of.000 kwh, which signifies a cost saving of 500 and 590 kg less fuel to transport and burn. NOISE TOO IS LOAD-DEPENDENT The condenser electronic controller, fitted as standard on all the ELFOENERGY units, automatically adjusts the fan speed as the thermal load decreases. As the fans are the greatest source of noise for this type of unit, it is clear how this feature brings important benefits, in particular at night, when the load is reduced but noise sensitivity is heightened.

SLIDING TEMPERATURE The elctronic adjustment of ELFOENERGY enables to suit the temperature of the water generated by the unit to the load conditions detected by system according to a SLIDING TEMPERATURE concept that searches for the best balance between power to be supplied and energy spent to produce it. A special measure in the refrigerating circuit prevents ice from forming in the base of the air exchanger. ALL-IN-ONE PHILOSOPHY ELFOEnergy is a unit "ready for use", including not only the components of the refrigerant circuit, but also a water circuit complete with pump (optional double pump), expansion vessel, safety valve, filling assembly and filter. As a result, the only requirement is to connect the unit to the water inlet and outlet pipes; in this way, the commissioning times and the possible problems during installation are reduced to the minimum. Controls keyboard WATER FILTER Water filter (external installation) steel mesh mechanical filter positioned at the exchanger inlet. Suitable for filtering water and trapping the impurities present in the water circuit. Mechanic steal-mesh filter is supplied standard on units with hydronic kit N 1 PUMP with standard, reduced or larger discharge head DOUBLE PUMP (otional) with standard, reduced or larger discharge head Expansion vessel 4

Thanks to the breakaway current reduction device, start-up takes place gradually, with the start-up current being limited during this period of time. The start-up current can therefore be reduced to.5-4 times the nominal current, meaning that the power systems and protection devices can be sized with lower parameters. (CMMBX)serial communication module to supervisor (MODBUS) The serial communication module to supervisor (MODBUS) is connected with the principal module through a comb connection (see lay-out on electrical panel). In this way the remote assistance and supervision are available through standard MODBUS protocol.it is possible to connect to a single supervisor system up to units. The connection to PC must be obtained through a converter RS45/22; the serial port RS22 admits as maximum a m length.the serial communication module to supervisor (MODBUS) is necessary when the unit is connected to ELFOCONTROL.

In this way an higher comfort and continuous energy saving are guaranteed. It optimizes unit energy efficiency, through a set point automatic modulation, according to the external conditions (temperature + humidity). It optimiezs also the defrosting time during winter operation. separately supplied accessories 19
