District Cooling is an efficient and environmentally friendly utility service
which provides chilled water from a centralised cooling plant (or cold water from the sea) through a network of pipes to multiple residential, industrial and commercial buildings for air conditioning purposes.
DESMI provides energy efficient pumping solutions for water intake (e.g. seawater) and centralized cooling plants (condenser pumps, chilled water pumps as well as pumps related to cooling tower applications).
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 pumps with flow capacities up to 4,000 m3/h, pressure ratings up to PN25 and a variety of medias such as seawater as well as glycol.
