to the seaside working environment, the shipbuilding industry frequently
encounters the problems of corrosion of newly blasted steel surfaces.
Oxidization occurs almost immediately after sand blasting of steel surfaces
when the ambient relative humidity is high (>80%RH). To avoid damage,
it is common practice to blow very dry air on the surface between the sand
blasting and protective coating stages.
Shipyards commonly use industrial
dehumidifiers to blow dry air over the blasted surfaces.
Unfortunately, the dehumidifiers currently available are extremely large
and heavy, and consume a great amount of electricity.
DHD Series 8000 and 18000 are new,
super high efficient dehumidifiers capable of the same or better
performance, while smaller in size and approximately half the weight of
comparable dehumidifiers. Most important of all, by utilizing advanced
heat pipe technology, the DHD Series uses only about half the electrical
power of conventional dehumidifiers. In
addition, the DHD Series provides hot drying cycle to cure coatings even
The DHD 8000 and 18000 are
