Multi-Scroll Air-Cooled Liquid Chillers Nominal cooling capacity: 47-155 Tons |167-547 kW | 50 Hz
eks/ME middle east 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 “eks 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 eks ME series.
The picture refers to the model: eks - BS / ME/AS 160-4-2ME
HIGH OUTDOOR AIR TEMPERATURE Specially developed to ensure reliable and durable operation in areas with extreme climate conditions: high outdoor temperature.
MAINTENANCE SIMPLICITY The arrangement of the components has been studied in detail in order to allow any operation of maintenance in the simplest and safest way.
COMPACT FOOTPRINT The size of the units has been optimized so as to minimize the space occupied, ensuring an easy accessibility to all the components.
MULTIPLE CONFIGURATIONS The various configurations and the vast number of available accessories make these units virtually suitable for all applications and every kind of installation.

eks/ME middle east Air cooled water chillers for outdoor installation designed to reach the lowest energy consumption and highest efficiency. The units are equipped with high-efficient SCROLL 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.
EUROVENT “A” Class 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.

PART-LOAD EFFICIENCY Every refrigerant circuit is equipped with two or three Scroll compressors and during the part-load condition it’s possible to reach the maximum efficiency and more capacity control steps.
EC FANS Electronically commutated axial fans give increased performance for reduced power input. Continuous speed control and outstanding efficiency, even in partial load operation.

Structure
Structure specifically designed for outdoor installation. Basement and frame in hot-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).
Compressor
Hermetic scroll compressor complete with motor over-temperature and over-current devices and protection against excessive gas discharge temperature. Fitted on rubber antivibration mounts and complete with oil charge.
EC-Fan
Premium-Axial-Fans with bionical shaped blades and high efficient EC (Electronically Commutated) external rotor motors, sealed in protection IP54 and thermal class THCL 155. The motor efficiency class complies with IE4.
Air heat exchanger
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.
Water heat exchanger
Plate-type Made of AISI 316 steel complete with water differential pressure switch. Shell covered with closed-cell neoprene anti-condensate material. Shell & tubes All extremely efficient with low refrigerant charge and very stable operating performance due to excellent refrigerant distribution, thermally insulated by vapour-proof closed cell.
Electrical board
Switchboard made according to standards IEC 204-1/EN60204-1, complete with contactor and protection for compressor and fans. Main isolator and door interlock safety device.
Control
The microprocessor controls the unit capacity by timing the compressors and checks the operating alarms with the possibility to connect to BMS.
Refrigerant circuit
Filter dryer, moisture-liquid sight glass, electronic expansion valve, HP and LP pressure sensors and safety valve.
Water circuit (Integrated):
Automatic charging cock with gauge, safety valve, expansion tank, water pump(s), water tank.
MAIN ACCESSORIES Spring vibration isolation Modulating fan speed condensing control (phase-cut) Soft start Compressor suction/discharge intercepting valve Remote control panel Max and min voltage relay

connected controller Thanks to a Multitasking Operating System and to the adoption of standard protocols, local and remote connectivity the controller used in eks chillers is the most advanced technology available.
NEW OPERATING SYSTEM New Multitasking Operating System ensures optimal system resource usage, extended datatypes for user application (32bit floating point numbers) application speed increase and independent protocol engines.
CONNECTIVITY The controller has two integrated Ethernet interfaces, three serial interfaces and two USB ports. A great choice of communication protocols is possible (Modbus, Carel, BACNet, LON, Konnex, TCP/IP, HTTP, FTP, DHCP, DNS, NTP, SNMP and many others).

CLOUD SERVICE Plug & Play solution for tERA platform connection. All tERA services are available just connecting the Ethernet plug to your home or office network, without the need for an external connection box.
www.euroklimat.it
application software ekapt The application software “ekapt” developed for eks 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, On-Off 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 or 2 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.
Web commissioning tool Trought internet browser, inserting the IP address of the control card, it will be possible to access the “ekapt” application in order to see and edit service parameters. The application is divided in: Main: in which are shown the main status parameter of the unit; Synoptic: main unit parameters, according to the circuit number and Unit live trend available. Parameters: it is necessary to be logged-in to open the Parameter menu. It is necessary to be, at least, Service user to be able to edit all the parameters. Alarms List: alarms list, with start and end period of the alarm.
