Blygold PoluAl XT MB, an anticorrosion coating resistant to bacteria and fungi in line with the European regulation on biocides (BPR)
Blygold PoluAl XT-MB - Corrosion & Microbe resistant HX
Heat exchangers used to cool down an airstream or room are often exposed to corrosive environments and microbiological growth. The condensation on the fins and the airborne pollution create the perfect conditions for corrosion and micro biological growth.
Both phenomena, corrosion and microbiological growth, will reinforce each other. Corrosion will create rough surfaces that increases the adhesion of pollution and microbes. Organisms will only grow if they are able to stick to a surface. Microbes, once settled on a surface, are able to create a very corrosive local microclimate that will affect the material they grow on.
The growth of bacteria and mould on chilled water or evaporator coils creates hygienic and smell issues. The typical smell of air-conditioning, also called dirty sock syndrome is, in fact, caused by the presence of these organisms.
Special Coating
Blygold PoluAl XT-MB is a corrosion protective coating for cooling coils and evaporators. The coating shields vulnerable metals from aggressive environments. The aluminum content in the coating provides the necessary heat conductivity to make sure that coated heat exchangers have an optimal cooling capacity. Special additives ensure the applied coating film is bacteria and fungi resistant. After treating evaporators or cooling coils these articles should be considered “treated articles” and labeled as such. The efficiency of the coating to resist bacteria and fungal growth has been tested and is available upon request.
Special application
A good coating will only perform when applied in a high quality process. Coating heat exchangers requires specialists that are able to apply the coating on every piece of bare metal present in a heat exchanger. Blygold uses proprietary spray techniques that can only be practiced by certified applicators. These qualified applicators are required to make sure a corrosion and micro-organism resistant heat exchanger is created. This is preferably done in a conditioned Blygold workshop but is, under restricted circumstances, also possible on-site.
