Kurita - Dropwise Technology
From Paper Solutions Technologies
Kurita Dropwise Condensation Technology is a patent pending technology to increase operating efficiency and conserve energy in industrial production facilities. This technology can be applied without apploying any additional system equipment. The KURITA DW product is dosed continuously into the steam line in front of the target device creating a water repellent film on the surfaces. Increasing the water repellency greatly improves heat transfer efficiency. The productivity of industrial processes increases significantly. At the same time the steam consumption is reduced leading to less fuel consumption and cutting down costs for water and energy. Kurita Dropwise Condensation Technology is a sustainable technology leading to a reduction of carbon dioxide emission supporting the development of an eco-friendly society.

More about Dropwise Technology
The dryer constitutes up to 40 % of the total energy costs. Rotating cylinders are heated to remove residual moisture, and at the end, the paper only has from 2 to 9 percent of remaining water. When this operation takes place, a water film always forms due to the centrifugal forces and even a very thin water film layer acts as insulator and inhibits the heat transfer significantly. As a result, more steam is required to equilibrate temperatures, and this situation leads to higher costs, higher maintenance charges, higher steam pressure and a decreased production.
As a result of years of experience, Kurita developed our Dropwise technology, where heat transfer improves by forming a water-repellent film on surfaces.

Kurita Dropwise Technology (Paper Industry) - Video
Paper production involves several processes in which minor details could lead to a significant increase in costs. The paper dryer section is the portion of this process where the remaining water is evaporated by the supply of heat energy. As a result of years of experience, Kurita developed our Dropwise technology, where heat transfer improves by forming a water-repellent film on surfaces.
