Heating and Domestic Hot Water

Aquapack

The Aquapack AP range of pressurisation units are designed to maintain the water pressure in heating and chilled water systems for domestic and commercial situations. The range is part of the Aquatech Pressmain product offering, now available through Dutypoint too.

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