District Heating is an energy distribution network
that transports heated water generated in a centralised utility through piping to residential homes and commercial buildings primarily in urban areas.
District Heating is clean, efficient and cost-effective due to its flexibility, scale of production and optimal heat generation conditions.
The heat is often obtained from a CHP (Combined Heat & Power) plant burning fossil fuels or increasingly also biomass a.o. District Heating plants can provide higher efficiencies and better pollution control than localised boilers.
DESMI provides energy efficient pump solutions both for applications in the heat production plants as well as for the
transmission and distribution network.
The DESMI pump solutions are recognized as being highly energy efficient with low NSPH values. The pumps have a long life cycle and are very maintenance friendly.
The DESMI centrifugal pump range comprise of:
• NSL in-line pumps for high pressure and high capacities.
• NSLV/H – end suction pumps for high pressure and medium/high capacities.
• DSL in-line pumps for moderate pressure and even larger capacities than NSL.
• ESL in-line pumps for lower pressure and capacities.
We are able to supply flow capacities up to 5,400 m3/h, pressure ratings up to PN25 as well as temperature solutions below 150 degr. C.
More than 500 District Heating project supplies recorded in our archives.
