PressDS

Compact and totally enclosed digital pressurisation units with electronic pressure transducer and user-friendly microprocessor for use on sealed system in order to provide a minimum system pressure requirement.

The PressDS (Pressurisation/Dosing System) is a floor standing, additive top-up mixing pressurisation unit with a 4 litre break tank to be connected to the mains supply. 18 litre tank for additive storage. Each time the unit tops-up the system with water, it also automatically adds additive from a dedicated tank at a predetermined rate, reducing intervention and maximising system protection. The correct fluid mix is blended on demand at the time of system top-up. Available with double pump (for duty/standby configuration).
