Dual Screw Compressor Air Cooled Chiller With High Efficiency
■ The environment-friendly R134a refrigerant delivers outstanding performance, saves electricity, contains no chlorine, does no harm to the atmospheric ozone layer, and therefore has an unrestricted term of use.
■ The emission of CO2 is efficiently reduced, alleviating the increasingly severe urban heat island effect and enabling green buildings .
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 .
