Pressurisation Units

Pumps UK carry out service, installation and maintenance of pressurisation units in London and the South East. We can maintain all makes of pressurisation units on heating and chilled water sealed system. We also service expansion vessels and can carry out WSE on pressure vessels.

Cold water Pressurisation units allow for the pressurising of both hot and cold water systems and are most commonly used in order to eliminate the need for a cold water storage system on the roof of a building or where a header tank is not available. Units often come with operating pressure switches and often high and low pressure interlock switches.
