    Capacity Continuous Adjustment Air Cooled Screw Chiller With Chiller Manage System

     

    The unit adopts a brand new economizer circulation design.
    The electronic expansion valve implements precision control,increasing the over-cooling degree of the unit, and greatly improving the cooling capacity and cooling efficiency of the unit.

     

    General Specifications

     

    Environmental Friendly-EKAS is an air cooled screw chiller which use dual screw compressor with R134a refrigerant

     

    High Efficiency-The “Apollo”/“Apollo+” stands for high efficiency/ extremely high efficiency on partial and full load operation , thanks to dual screw compressor , sub-cooling design , M shape condenser ,economizer , shell and tube evaporator ,electronic expansion valve and patent aerofoil aluminum fan .

     

    Capacity Continuous Adjustment -With intelligent controller , EK chiller performs a prompt adjustment according to system load to ensure the precisely chilled water temperature . What’s more , it will unload automatically at extremely high ambient temperature to protect compressor.

     

    10.1” Touch Screen -is directly connected to the microprocessor , providing monitoring history data recording ,safety protection ,and more convenient operation .

     

    Widely Applications -EKAS is the idea solution for commercial building & industrial applications that required high performance ,continuous operation , lower operation and maintenance cost .

     

    BMS (Optional)-EK provide an RS485 standard communication interface , which is more convenient to joint with building management system . Standard protocol includes BacNet ,Modbus and Lonwork .

     

    Chiller Manage System (Optional)- EK provide intelligent CMS for centralized control on several air cooled screw chillers to balance each unit running time ,and perform automatically switchover on a fault unit , ensuring the whole system stable running & energy saving .
