Italcoat produces coated aluminium with hygroscopic lacquer, ideal for the manufacture of energy recovery rotors. Hygroscopic lacquer makes products more resistant to the corrosion caused by humid environment, e.g. in marine environment. In addition, it limits the bacteria formation and it’s free of Silica Gel, a possible source of bad smell.
Aluminium is chemically degreased and lacquered on both sides with an innovative hygroscopic and anticorrosion formulation developed by our R&D department, named Hygrosieve®. This coating offers a lot of advantages: no risk of coating pulverisation, selective adsorption of water moisture with the exclusion of pollutants, reduction of the flow rates of refrigerant fluid, the chance to add biocide additive to the formulation.
The Hygrosieve® hygroscopic lacquer is characterized by a Molecular Sieve effect that improves the performance in terms of selective vapour adsorption /desorption with a 15% of energy saving.
The coated aluminium with hygroscopic lacquer absorbs moisture from the air and reduces the ventilation system’s energy consumption.
Typical Alloy: 3003
Temper: H18 – H19
