Note on "Vessel Size / Configuration" column: Some models are specified with a physical vessel size (e.g., 8 ltr, 18 ltr, 24 ltr), while others are listed as "With Pressdrive 05". This indicates a configuration using the "Pressdrive 05" controller, where a separate vessel size may not be explicitly stated in this column.
Mechanical / hydraulic
For every Acuapres unit, a pressure vessel must be fitted on the discharge pipework. The minimum recommended size for this vessel is 24 ltrs.
