Operation Pressure Range

This section presents graphical data illustrating the compressor's operation pressure ranges. The graphs show condensing pressure versus evaporation pressure under continuous and transitory operation conditions.

Graph 1: Condensing Pressure vs. Evaporation Pressure

X-axis: Evaporation Pressure [bar] (0 to 16)
Y-axis: Condensing Pressure [bar] (50 to 170)
Temperature scales (°C and °F) are provided below the X-axis.
Lines indicate 'continuous operation' and 'transitory operation'.

Graph 2: Condensing Pressure vs. Evaporation Pressure (Alternative Scale)

X-axis: Evaporation Pressure [bar] (0 to 16)
Y-axis: Condensing Pressure [bar] (0 to 25)
Temperature scales (°C and °F) are provided below the X-axis.
Lines indicate 'continuous operation' and 'transitory operation'.
