The Special Requirements of DI Water Storage

Deionized water differs significantly from ordinary water due to the removal of ions and impurities that can otherwise facilitate corrosion or biological growth. Because DI water is highly reactive and aggressive concerning materials, improper storage vessels can contaminate the water or degrade over time.

Key storage requirements for DI water include:

• Ultra-high corrosion resistance: DI water aggressively attacks many conventional metals and coatings.
• Hygienic, inert surfaces: Prevent contamination and microbial growth.
• Non-leaching materials: Avoid release of metals, organics, or other substances into the water.
• Seamless integrity & tight seals: Prevent ingress of contaminants.
• Long-term chemical stability: Maintain water quality over extended storage.
• Regulatory compliance: Meet FDA, NSF, ISO, and other relevant standards for water purity.

What Are Glass-Fused-to-Steel (GFS) DI Water Tanks?

GFS tanks are innovative storage tanks made by fusing a glass enamel coating directly onto steel panels at very high temperatures (typically 820°C to 930°C). This high-temperature fusion bonds the glass chemically and mechanically to the steel surface, forming a hard, inert, and impervious coating that combines the strength of steel with the hygienic properties and corrosion resistance of glass.

For DI water, this means the tank interior surface is non-reactive, non-porous, and durable, preventing corrosion and contamination while maintaining the water's purity throughout storage.

Advantages of GFS DI Water Tanks

• Unrivaled Corrosion Resistance: The dense glass enamel coating is highly resistant to aggressive chemistry of DI water, withstanding acid, alkali, and oxidative conditions better than epoxy-coated steel or stainless steel tanks.
• Chemical Inertness: Glass is inert and non-leaching, ensuring the DI water doesn't pick up metals or contaminants, preserving quality for pharmaceutical, semiconductor, or food-grade applications.
• Hygienic Surface: Smooth and non-porous surfaces resist biofilm formation and bacterial growth, critical for ultra-pure water storage.
• Durability and Longevity: GFS tanks have a lifespan exceeding 30 years with minimal maintenance, outperforming alternative coatings or stainless steel tanks prone to pitting and corrosion.
• High Structural Strength: The steel core provides strength against pressures, thermal cycling, and environmental stresses while the glass coating protects the internal surfaces.
• Seamless Assembly: Bolted modular design allows quick construction and future expandability without welding on site, reducing contamination risk and installation time.
• Regulatory Compliance: Center Enamel GFS tanks meet NSF/ANSI 61 for drinking water safety and predicate international certifications (ISO 9001, AWWA D103-09, OSHA, ISO/EN 28765) ensuring global acceptance.
• Environmental Sustainability: The glass enamel coating is inert and recyclable, and with long service life, the tanks reduce lifecycle environmental impact.
