The purpose of a supply flow pump cabin is to increase pressure in the supply line and thus ensure enough differential pressure at end consumers during cold periods.
In the past, it has been necessary to increase pressure across the entire pipeline network to ensure a sufficient level of differential pressure for end consumers at the outer reaches of the area. By installing a Standard pump cabin at a strategic location on the pipeline network, substandard supply conditions can be eliminated, providing the right amount of pressure and removing the need for a pressure increase at the heating plant.
Here at Priess, we want to make things easy and convenient for our customers by delivering cabins with complete installations which have been pressure-tested and EAFIS-tested (inspection and testing ahead of deployment). This means that the only thing needed for installation is connecting the district heating pipes and the supply cable.
The purpose of the return flow pump cabin is to increase pressure on the return pipeline and thus ensure sufficient pressure to return to the heating plant.
It has previously been necessary to increase the pressure across the entire pipeline network to increase pressure for consumers at the outer reaches of the area and ensure sufficient pressure to return to the heating plant. Priess-Pipeteq means that it is now possible to install a return flow pump cabin in an area with declining elevations where the static pressure increase on the supply pipeline provides enough differential pressure, but where the heating plant must raise the pressure to ensure returning is possible and to overcome resistance in the return pipeline and static elevations.
It is possible to combine the two features above and create a cabin which contains both: supply and return flows. This means that the cabins will be larger here than they would be separately.
