Power plants generate the energy that keeps society running — and moisture is one of the most persistent threats to the equipment that makes this possible. Condensation on generators, boilers, turbines, condensers, and reheaters causes corrosion that shortens component lifespan, triggers unplanned maintenance, and delays return to service. DST desiccant dehumidifiers protect power plant equipment during shutdown, lay-up, and preservation — in hydroelectric, nuclear, thermal, and wind power facilities across four continents.
When power plant equipment is taken offline for maintenance or seasonal shutdown, the warm, moist air that contacts cold metal surfaces creates condensation — initiating corrosive processes that can cause significant damage within days. In nuclear power stations, reactor vessels and cooling systems require precise humidity control during maintenance to prevent intergranular corrosion on austenitic stainless steel components. In thermal power stations, boilers, reheaters, and feed pipes are all vulnerable during wet and dry lay-up periods.
DST dehumidifiers supply dry air directly to enclosed spaces, equipment interiors, and machinery rooms — maintaining relative humidity below 50% and eliminating the conditions in which corrosion can occur. The result is faster return to service, reduced maintenance costs, and longer equipment lifespan across every type of power generation facility.
See how DST desiccant dehumidification systems are deployed in power generation environments — from hydroelectric turbine halls and nuclear reactor rooms to wind turbine nacelles and thermal boiler preservation. Our systems protect critical equipment during shutdown, maintenance, and long-term lay-up with reliable, low-maintenance humidity control.
DST’s most extensive power generation partnership — spanning turbine preservation at Ringhals nuclear power plant, hydroelectric mounting halls at Messaure, Bastusel, Porjus and Stalon, and gas turbine preservation at Kimstad, across more than 20 years.
Two separate DST projects for Vestas — one of the world’s leading wind turbine manufacturers — covering wind power plant humidity control in 2002 and wind turbine dehumidification in 2019.
DST supplied power plant conservation dehumidification for E.ON in the Netherlands, protecting equipment from corrosion during an extended lay-up period.
DST has been supplying dehumidification solutions to the power generation industry since 1992 — across hydroelectric, nuclear, thermal, and wind power facilities in Sweden, Norway, France, Poland, Japan, the UK, and beyond. All systems are configured to the specific equipment, shutdown conditions, and environmental requirements of each installation.
