FAQs

A pressurisation unit maintains the correct pressure within sealed heating or chilled water systems. It automatically tops up water when pressure drops, helping to prevent air ingress, system inefficiencies and potential damage to components.

Pressurisation units are commonly installed in commercial and multi-occupancy buildings, including offices, hospitals, schools and residential developments, where sealed systems require consistent pressure control.

By maintaining stable pressure levels, pressurisation units help prevent issues such as cavitation, air locks and component stress. This supports system longevity, reduces the risk of breakdowns, and ensures reliable operation.

Regular servicing is recommended as part of a planned preventative maintenance (PPM) schedule. Routine checks help ensure the unit is operating correctly, identify potential faults early, and maintain overall system performance.
