  • Description

    The PH Units are robust and reliable floor mounted pressurisation units ideally suited to industrial or commercial applications.

    For use on sealed systems in order to maintain the minimum operating system pressure.

    The open design increases serviceability and provides the option of manual dosing via the tank. A multi-stage pump is utilised in order to drastically reduce any risk of seizure, commonly found with peripheral pumps found in most other pressurisation units.

    PH Units are available with either mechanical pressure switch control or a digital controller for more advanced features and BMS communication. Digital versions also offer the option of a second standby pump along with a QuickFill facility in order to aid the initial filling of a sealed system.

    The digital controller provides 2 programmable volt free contacts as standard which can be configured to high/low pressure, common fault, pump fault, system fault, water leak, service due alarms. There is also the option to expand providing an additional 3 volt free contacts.
