Pressurisation Units
The "Peakline C" is a high specification duplex pump pressurisation unit is ideal for controlling and maintaining pressure in sealed heating and chilled water systems. "Sealed" systems steadily lose small amounts of water via leaks, maintenance operations, vapour from glands etc. The Peakline C continuously and automatically monitors system pressure and tops it up as required. The unit provides low and high pressure volt free switching for boiler or chiller safeguarding. It should be installed in conjunction with an expansion vessel (see separate leaflet) to accommodate system water thermal expansion. Our sales office will be pleased to help with selection of an expansion vessel.
Peakline units are also available as a single pump model, the Peakline 'N'. Please contact us for further details.
