Blygold PoluAl XT Dry cooler protected Protection of Climate with PoluAI XT Installations Heat exchangers are subject to severe corrosion because of their construction, which usually combines dissimilar metals, and the environment that they are exposed to. Corrosion and pollution of heat exchangers will directly affect the performance of the air conditioning system. The heat exchanger must be sealed off from the environment in a manner that will not reduce its heat transfer or cause a pressure drop. If this can be accomplished, the cooling capacity will remain intact and energy consumption can be controlled. To achieve this, have your heat exchanger treated with the Blygold PoluAI XT Corrosion Protection System. Blygold® AMERICA INC. Blygod~ I AMERICA •• ;"" .1\" 'i" ~" c,:····, \'1 ~.•. t. . .'.

This goldcolored polyurethane coating has new important features that make the treatment easier and faster. PoluAI XTcan be applied directly to the copper and aluminium and therefore expensive pre-treatments are no longer needed. The heat conductive pigmentation in the coating is oriented in the 3-dimensional coating structure so that it creates a very high chemical resistance at a lower layer thickness. Coatings on heat exchangers should not exceed a thickness of more than 25 micron or' mil to prevent an unnecessary increase of pressure drop and thermal resistance. In combination with the unique application procedures of certified Blygold applicators the PoluAI XT is the best available option to prevent air conditioning failure and unnecessary energy consumption.
