Pressure switch / MacPress


MacPress is a regular pressure switch for hidrofor systems with expansion vessel.

MacPress must be installed on the pipe, where it can sense the system’s pressure. The device operates between two pressure value: a starting, and a stopping pressure value.

When the system’s pressure drops below the pre-set start pressure (by opening a tap), MacPress sense it, and start the pump. When the water collecting process is over, and we close the tap, the pressure will increase. When the pressure reach the pre-set stopping value, stop the pump.

The housing colors: Blue is one phase, red is three phase
