SiO₂-based surface protection for improved durability
Do you have to deal with issues like metal leaching, corrosion and scaling? If you are in the water business, you have most likely encountered these and other challenges. Sealix® is a new generation of brazed plate heat exchangers that creates a barrier against these issues and keeps water running longer.
Sealix® is a revolutionary SiO₂-based thin-film technology that increases corrosion resistance, decreases the tendency for scaling, and increases durability. A protective layer is applied to all surfaces that come into contact with water to increase the lifetime and operational safety of the entire system, reducing maintenance costs and unplanned downtime.
How Sealix® Keeps Water Running
Sealix® protects the surface of the heat exchanger and increases corrosion resistance. Customized chemical compounds modify the surface energy and enhance the mechanical and thermal stability. This improves the surface behaviour in terms of scaling, and maintains the high thermal and hydraulic performance of the brazed plate heat exchanger – and is well-suited for water to water applications.
Reduce maintenance costs
Sealix® surface protection improves the system’s efficiency and reduces maintenance costs related to breakdowns and unplanned downtime. The innovative self-cleaning technology reduces deposit formation and prevents contamination while protecting the surface.
Dramaticall reduce scaling with Sealix®
Sealix® treated and untreated copper-brazed stainless-steel samples were immersed in a salt/water solution at a temperature of 50°C and for a duration of 9 hours to visualize the significant difference in their corrosion resistance.
Already proven in practice
In Central Europe, a large number of Sealix® units have already been installed in domestic hot water systems, where they work without any problems – and exceed the operating time of the previously used standard products many times over.
Internationally recognized and approved
SiO₂ -based surface sealing is recognized worldwide and approved by the United States Food and Drug administration, the European Food Safety Authority and the Japan Inspection Association of Food & Industry Environment.
