maximum standstill pressures of 135 bar at high side and 90 bar at low side – see Chapter 3.2.1
"Safety relief valves". Refrigerant flow and heat transfer have been optimized for best performance.
NOTE: Throughout these guidelines, pressure values shown with the bar(a) or bar unit are
absolute pressures. For values in relative (gauge) pressure, bar(g) will be used.
NOTE: The compressor is only one component which must be combined with many others to
build a functional and efficient refrigeration system. Therefore the information in this manual
relates to Copeland Stream semi-hermetic compressors for CO
applications with standard equipment and accessories only.
