Designed for commercial and industrial applications, the PH1D combines the robust, floor-mounted construction of the PH range with a digital controller for more advanced pressure management. This provides greater control over system operation and allows additional alarm and monitoring functions to be configured to suit the installation.

The open construction provides straightforward access to key components for servicing and maintenance, while the multistage pump helps reduce the risk of seizure associated with peripheral pumps commonly used in pressurisation units. Manual dosing can also be carried out through the tank where required.

The wider PH range is also available with digital controller options for more advanced control, monitoring and BMS communication. Digital versions can be supplied with a second standby pump and QuickFill functionality to assist with the initial filling of a sealed system.

The digital controller provides two programmable volt-free contacts as standard, which can be configured for high or low pressure, common fault, pump fault, system fault, water leak or service due alarms. A further three volt-free contacts can also be added where additional alarm or monitoring outputs are required.
