Sealed System Pressurisation Units

Sealed System Pressurisation Units

Sealed system pressurisation units automatically maintain water pressure in closed heating and cooling systems, removing the need for manual top-ups. When pressure drops due to leaks or natural loss, these units detect the change and restore the system to its correct operating level, keeping everything running safely and efficiently.

 

They help prevent airlocks, reduce system wear, and minimise downtime, making them essential for larger or more complex installations where manual monitoring isn’t practical. Our range includes compact, reliable units from leading brands that are purposely designed for simple installation and dependable long-term performance.
