Description

20G STEEL COMPRESSED WATER STORAGE TANK
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.

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
Check Pre‑Charge Pressure: Before first use, verify the air charge (often around 7–10 psi, depending on system).
Mount Securely: Use a stable, level surface to prevent vibration and maintain diaphragm health.
Inspect Annually: Check for any signs of stress or corrosion, especially on weld seams.
Flush occasionally: If water sits for a long time, flush the tank periodically to refresh stored RO water.
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.
