Pump Technology Ltd can supply a range of units for maintaining pressure in sealed heating or chilled systems.
The main benefits over previous systems which used feed and expansion tanks to accommodate expanded water are many.
Large volumes of water are no longer required to be stored at the top of the building.
Expansion vessels can now be used in place of the storage tanks.
The Feed and expansion tank being open to atmosphere allows water to evaporate making unnecessary demand on this precious resource.
Sealed systems reduce corrosion to an absolute minimum by sealing the system content from the atmosphere, and only adding fresh water to replace losses through leakage.
Sealed systems also offer the possibility of operating at higher temperatures if required which permits lower circulation rates, smaller pumps and reduced pipe work dimension with obvious cost savings.
