“NET-VIRA Nordic Villa" is the company's introduction of advanced membrane deoxidation technology from Europe, and is developed by the boiler design team based on the actual working conditions of China's boiler industry water treatment. Patented products of intellectual property.

In the boiler feed water treatment process, oxygen removal is a very critical part. At present, China's industrial boilers use demineralized water or desalinated water as boiler feed water. Because oxygen corrosion is a slow process, some enterprises do not pay attention to boiler feed water deoxidation. On the other hand, due to the lack of stable and reliable oxygen removal technology, the problem of dissolved oxygen corrosion in industrial boilers in China is quite special, resulting in a shortening of the average life of industrial boilers by more than 1/3, causing huge economic losses to enterprises and countries.

Boiler oxygen corrosion generated substances mainly iron oxide will deposit or adhere to the boiler tube wall and heating surface, forming insoluble iron and poor heat transfer, iron scale will cause pits on the inner wall of the pipe The drag coefficient increases, and when the pipeline is seriously corroded, a pipeline explosion accident may occur. GB1576-2008 "Industrial Boiler Water Quality" standard stipulates that steam boilers with a evaporation capacity of 10 tons/hour or more and 7MW hot water boilers must be deaerated, and steam boilers of less than 10 tons/hour and 7MW hot water boilers are found to have local oxygen. In the case of corrosion, oxygen removal measures should also be taken. Many boiler feedwater treatment workers have been exploring efficient, economical and environmentally friendly oxygen removal methods for many years.
