Heron GRO-400 Commercial RO Water Purifier Machine – 400 GPD

The Heron GRO-400 Commercial RO Water Purifier Machine is an industrial-grade powerhouse designed to provide high-volume, 100% pure drinking water. In large-scale environments like garments factories, corporate headquarters, and educational institutions, a standard filter simply cannot keep up with the demand. This 400 GPD (Gallons Per Day) model is engineered to be a workhorse, delivering safe and mineral-balanced water to hundreds of users every single day without fail.

Why Your Large Organization Needs the Heron GRO-400?

Managing drinking water for a massive workforce is both a cost and a health challenge. Relying on jar water is not only expensive but also carries risks of contamination. The Heron GRO-400 Commercial RO Water Purifier Machine eliminates these concerns by producing approximately 1,500 liters of purified water every 24 hours. Whether you are running a multi-shift factory in Gazipur or a busy school in Dhaka, this machine ensures that your team stays hydrated with water that meets global safety standards.

Advanced 5-Stage Purification Technology

The Heron GRO-400 Commercial RO Water Purifier Machine utilizes the world’s most trusted purification method: Reverse Osmosis (RO). Developed with USA technology, this 5-stage process is specifically designed to tackle the harsh groundwater conditions in Bangladesh, including high iron, arsenic, and total dissolved solids (TDS).

1. Stage 1: Sediment Filter (PP): Removes large particles like dust, mud, sand, and rust.

2. Stage 2: GAC Filter: Absorbs chlorine, bad odors, and organic chemicals.

3. Stage 3: CTO Filter: Further refines the water by removing pesticides and VOCs.

4. Stage 4: High-Flow RO Membrane: The “brain” of the Heron GRO-400 Commercial RO Water Purifier Machine. It filters out 99.9% of bacteria, viruses, and heavy metals.

5. Stage 5: Taste & Odor Filter: Ensures the final output tastes as fresh as natural spring water.

According to the , RO technology is the gold standard for removing dissolved contaminants that boiling or simple filters cannot touch.
