DAB E.SYBOX multistage intergrated system

The DAB ESYBOX is shipped with a default set point (SP) of 3 bar, a default restart pressure differential (RP) of 0.3 bar and a pressure tank with a default pre-charge of 2 bar.

If the set point is changed, and/or the restart pressure differential is changed, then pre-charge of the pressure tank needs to change.

If this is not done, premature failure of the tank and subsequent damage to the pump from cycling can occur with the failure not being covered by warranty.

As per the DAB ESYBOX manual, the formula for calculating the correct pressure tank pre-charge for the DAB-ESYBOX is:

Pre-charge (bar) = SP (bar) – RP (bar) - 0.7 bar
where
SP = Set Point (adjustable between 1.0 and 6.0 bar, default 3.0 bar)
RP = Restart Pressure Differential (adjustable between 0.1 and 1.0 bar, default 0.3 bar)
0.7 bar is a constant.
