BLUE GLASS 4753: the internal treatment of Styleboiler tanks

Styleboiler’s goal is the constant improvement of the performance of our products, and to ensure the quality of sanitary water, it is essential to apply an internal treatment to the tanks.

Our hot water heaters are lined with food-grade inorganic glass porcelain (ENAMEL), applied at 860°C according to the DIN 4753 method. But the true highlight is the vitrification system, based on the exclusive “BLUE GLASS 4753”.

This treatment not only prevents corrosion and contamination but ensures superior durability of the tanks. This advanced technology protects against corrosion, contamination, and offers a series of unique advantages:

  • Certified protection:

The tank’s internal coating creates a clean and safe environment for sanitary water, proven by WRAS certification and KTW-BWGL conformity certification.

  • Material safety:

Our treatment includes antimicrobial technology, used and tested in a wide range of ACS products for over 50 years, ensuring the absence of toxic or harmful substances that could affect health.

  • Extra durability:

Thanks to a highly specialized tank coating, the water heater is protected from the corrosive effects of water, ensuring an exceptionally long lifespan.

The mixture used is unique and not available commercially. Each individual ingredient is selected with extreme care and mixed with expertise and attention, using methods perfected through decades of research. This process takes place exclusively within our facilities in Italy, where every stage is meticulously controlled to ensure exceptional results.

The “BLUE GLASS 4753” formula is the result of decades of research and development to create a unique eco-sustainable enamel. It represents a safe solution both for personal health and environmental protection, as it contains no nickel, one of the most common metals that can cause allergic reactions. Even in small amounts, the presence of nickel could contaminate water, with the risk of health problems such as asthma, respiratory issues, and, in rare cases, chronic nickel toxicity.

Styleboiler is the only company offering the “BLUE GLASS 4753” glass porcelain coating, combining artisanal tradition with technological innovation, confirming the excellence of “Made in Italy” in the field of internal treatment of ACS tanks for over 50 years.
