Pressurisation Units & Sets

We supply a complete range of Pressurisation Units for heating and chilled sealed systems available as one or two pump models with a choice of wall mounted or floor standing, from a wide range of Manufacturers including Calpeda, DAB, Flamco, Lowara and Spirotech.

A pressurisation unit is a means of pressurising a system being heating or hot and cold water and generally eliminates the need for a cold water storage system in the roof. They are suitable for use in a wide range of applications where a header tank cannot be fitted, pressurisation units are designed to replace water that has been lost through system leakage and to maintain the system design fill pressure in sealed heating and chilled water systems

This arrangement causes air to be absorbed into the water with resultant corrosion of heat exchangers, pipework and boilers. A sealed system limits air intake and corrosion to a minimum and only needs fresh water make-up to replace any losses caused by leakage. Higher flow temperatures may be used in sealed systems which, with larger temperature drops, permit lower water circulation rates, smaller pumps and reductions in pipework sizes, all with obvious cost-savings.

Pressurisation UnitIncorrect calibration of the unit’s settings or pre charging of the expansion vessels will cause the system to malfunction.

  • Maintains minimum pressure requirements of low / medium temperature sealed heating sealed systems.
  • Choice of floor standing or wall hung models
  • Standard controls or digital controls
  • Standard controls or electronic controls

Most units are available from stock and can be supplied with expansion vessels, air separators and dosing pots.
