Aquapack AP Series of Pressurisation Units with Degassing Options

PED compliant pressurisation unit designed to maintain the water pressure in heating and chilled water systems for domestic and commercial situations

AP Series Pressurisation Unit.
New options – Dual system pressurisation. Degassing active vacuum.



Our Aquapack AP Series of PED compliant pressurisation units are designed to maintain the water pressure in heating and chilled water systems for domestic and commercial situations.

Their principle of operation is to accommodate the expanded water volume as the temperature rises and then refill the system as the temperature decreases and the pressure drops.

Floor or wall mounted, the series offers options to deal with systems of temperatures of 3°C to 90°C, a fill pressure of 0.8bar up to 14.0bar and a system content of 50,000 litres of water. All with twin pumps and a building management signals package.

They have been designed ergonomically so there is no need to kneel when checking the controls, built to last and run quietly and efficiently to save energy. The connections can be supplied on the right hand side or the left hand side of the unit or a combination of the two in order to facilitate the installation.

Available with several problem solving options:

Aquapack Dual – Dual configuration to handle heating and chilled water systems at the same time, saving money and installation time.




Aquapack DG – A degasser, safeguarding optimal heat transfer and protecting against corrosion. Plantroom leak detectors for peace of mind.




Aquapack Change-over – For resilience / backup, these units can be used with an auto change-over panel. The change-over panel spreads the workload between the units in normal operation and, in the case of unit failure, will automatically switch units to ensure continuity of service.
