Description

20G STEEL COMPRESSED WATER STORAGE TANK

The 20G Steel RO Storage Tank is a premium, high‑capacity pressure vessel designed specifically for reverse osmosis systems. It features a virgin polypropylene liner and a chlorobutyl diaphragm that ensures clean, pure water and long-term durability. With a steel outer shell, precision welds, and deep‑drawn domes, this tank offers excellent structural integrity and reliability under pressure. When your RO system fills the tank, it stores pressurized water so you can dispense RO water instantly — without waiting for filtration.

Key Features & Benefits

• Large 20-Gallon Capacity — Stores a significant volume of RO-purified water, reducing pump on/off cycling.
• High Operating Pressure — Rated for up to 100 psi, enabling consistent delivery.
• Premium Internal Diaphragm — Uses a cured chlorobutyl diaphragm with a PP liner for contact-safe, clean water.
• Stainless Steel Connection — The water inlet uses a stainless-steel fitting to avoid wear and ensure longevity.
• Pre‑Pressurised for Convenience — Ready to use out of the box; no need for manual pressurisation during setup.
• Robust Frame — Steel shell with strong welds guarantees structural strength and long-term reliability.

Technical Specifications

Use Cases & Applications

• Under‑sink RO systems — Perfect where you need stored RO water for a faucet without delay.
• Water‑dispensing businesses — Useful where RO water is dispensed to customers rapidly.
• Portable or mobile RO setups — Strong, steel body makes it rugged and transportable.
• Backup water storage — Acts as a buffer in systems with variable demand.

Installation & Maintenance Tips

1. Check Pre‑Charge Pressure: Before first use, verify the air charge (often around 7–10 psi, depending on system).
2. Mount Securely: Use a stable, level surface to prevent vibration and maintain diaphragm health.
3. Inspect Annually: Check for any signs of stress or corrosion, especially on weld seams.
4. Flush occasionally: If water sits for a long time, flush the tank periodically to refresh stored RO water.
5. Replace When Needed: Though very durable, the diaphragm may wear over the years — replace it when capacity or pressure drops.

Why Choose This RO Tank Over Plastic Alternatives?

• Durability: Steel tanks are more rugged and resistant to cracks or degradation than plastic.
• Better Pressure Capacity: A Higher PSI rating ensures better performance and responsiveness.
• Longer Life: With a proper diaphragm and steel shell, this tank lasts many years with minimal maintenance.
• Taste & Purity: The PP liner and chlorobutyl diaphragm preserve water purity without leaching contaminants.
