1 Technical Catalogue ekv/me Air-Cooled Liquid Chillers with screw compressors Nominal cooling capacity: Tons kw 50 Hz
2 The harsh climate conditions typical of Middle Eastern areas make energy efficiency and extended operating limits even more crucial factors compared to usual conditions. Euroklimat introduces ekv ME the air cooled water chillers specifically studied and designed for Middle East. We have focused on energy efficiency and operating limits typical of Middle East climates while developing the ekv ME series. The picture refers to the model: ekv-b~b/he HIGH UTDR AIR TEMPERATURE MAINTENANCE SIMPLICITY CMPACT FTPRINT MULTIPLE CNFIGURATINS Specially developed to ensure reliable and durable operation in areas with extreme climate conditions: high outdoor temperature. Full load at 118 F Part load at 126 F The arrangement of the components has been studied in detail in order to allow any operation of maintenance in the simplest and safest way. The size of the units has been optimized so as to minimize the space occupied, ensuring an easy accessibility to all the components. The various configurations and the vast number of available accessories make these units virtually suitable for all applications and every kind of installation. 2
3 Air cooled water chillers for outdoor installation designed to reach the lowest energy consumption and highest efficiency. The units are equipped with high-efficient SCREW compressors, V condensing shape with increased surface and extremely efficient evaporator with low refrigerant charge and very stable operating performance due to excellent refrigerant distribution. EURVENT A Class SCREW CMPRESSRS EC FANS LATEST TECHNLGY INSIDE Eurovent Certification certifies the performance ratings of airconditioning and refrigeration products according to European and international standards. Every model of eks-me range is under A Class based on Energy Classification. Compressors configured for maximum efficiency with a high compression ratio and sophisticated three-stage oil separation system minimises oil dragging towards the system. Electronically commutated axial fans give increased performance for reduced power input. Continuous speed control and outstanding efficiency, even in partial load operation. Electronic Expansion Valve EC fans supplied as standard Microchannel coils 3

Basement and frame in galvanised shaped sheet steel with a suitable thickness. All parts are polyester-powder painted to assure total weather resistance (RAL 7035 standard colour, others on request). Semi-Hermetic compact screw compressor with step-less capacity control system. The sophisticated three-stage oil separation system minimises oil dragging towards the system. Fitted on rubber antivibration mounts and complete with oil charge. Low speed, axial-flow fans fitted with accident-prevention protective grille; directly coupled motor with built-in thermal cut-out and IP 54 protection degree; aerodynamic housing and wing profile blades increase efficiency and decrease noise level. Microchannel Microchannel technology increases the primary to secondary surface area ratio and reduces the tube s air shadow to provide maximum heat exchange through our condensers. Due to their small hydraulic diameter, microchannel aluminium tubes transfer heat more efficiently than the traditional round copper tubes. Plate-type (Desuperheater / Heat recovery) Made of AISI 316 steel complete with water differential pressure switch. Shell covered with closed-cell neoprene anti-condensate material. Shell & tubes evaporator All extremely efficient with low refrigerant charge and very stable operating performance due to excellent refrigerant distribution, thermally insulated by vapour-proof closed cell. Switchboard made according to standards IEC 204-1/EN , complete with contactor and protection for compressor and fans. Main isolator and door interlock safety device. The microprocessor controls the unit capacity by timing the compressors and checks the operating alarms with the possibility to connect to BMS. Filter dryer, moisture-liquid sight glass, electronic expansion valve, HP and LP pressure sensors and safety valve.

12 utstanding efficiency VFD - Inverter technology available The option VFD makes it possible to increase drastically the efficiency at part loads. By working always with the maximum efficiency an inverterdriven compressor equipped with ACVR (automatic continuous Vi regulation) can really offer impressive energy savings. A case study of a process cooling unit with air-cooled condenser showed about 25% energy saving in one year for instance. INVERTER AVAILABLE Latest generation screw compressors New compact screw compressors offer the highest efficiency both at design (EER) and seasonal (ESEER) conditions, thanks to the optimized fluid dynamics and the latest design and manufacturing technologies. Easy installation and accessibility thanks to all main fittings and checks on just one side. Designed for heavy-duty operation and equipped with top quality components. Single-pass S&T evaporator The single-pass shell&tube dry expansion evaporator is equipped with a unique patented refrigerant distribution system which has been optimized for R134a. The configuration counter-current of the flow is design to maximize performance and the plastic baffles are used to improve the water side performance and to avoid corrosion issues. 12
13 application software ekapt The application software ekapt developed for ekv chillers allows an easy access to the machine configuration and management parameters with the menu system organised by device. There are three password levels to allow three different access modes to the parameters (read only for assistance, edit for servicing, total access for the manufacturer). The main screen gives quick access to the user functions without a password (information on the status of the machine components, n-ff and machine operating mode, set points). PID control There are two types of PID control: - PID control on start-up - PID control during operation [kw] The start-up control must prevent an excess of requested power. Since at start-up the status of the load is not known but only the temperature is, the power must be entered little by little, waiting for the reaction of the system. The control during operation must be quick in order to follow any load variations and maintain the water temperature as close to the set-point value as possible. Compressor s envelope management The operating limits (hereafter defined as envelope) of the compressors are controlled. This control cannot be disabled in order to prevent the compressor from working outside of the safety limits dictated by the manufacturer. All of the compressors inserted thus contain the envelope data. When the operating condition is outside of the envelope, the alarm delay starts counting: if the operating condition remains outside of the envelope when the delay has elapsed, a specific alarm is activated, which stops the compressor; if, on the other hand, the operating condition returns within the envelope limits, the alarm delay counter is reset. Compressors power distribution ekapt application software provides management of the power distributed to the compressors in the best way possible to increase the efficiency of the unit. The behaviour of power distribution changes depending on the configuration, 1, 2 or 3 circuits and the power ratio between compressors. In the event of an alarm for one compressor, the next available compressor will be turned on as a replacement if the request is high enough. For units with two circuits and prevention active in one circuit, the rotation will compensate for the limited circuit by increasing the request on the available circuit. 13
