AquaTech Pressmain manufactures a range of pressurisation units for maintaining pressure in sealed heating or chilled systems.
The pressurisation unit range is designed to maintain a minimum set pressure in a sealed heating or chilled water system. Once the system has been initially filled via a quick filling loop, should the pressure fall below the cold fill pressure, the unit operates automatically to restore that pressure. If high- or low-pressure conditions should occur, the boiler or chiller operation can be interrupted via the volt-free contacts provided. The units use suitably sized expansion vessel from the Aquatank range of replaceable diaphragm vessels tested to BS 6144. Where system volumes exceed 50,000 litres open format tanks can be utilised.
The range of Aquatech pressurisation units includes the Minipack Baisc, Minipack Enhanced, Aquapack AP Series, Spillback SB Series, Spillpress 'sp2et' series and the Aquaspill AS Series
