Eiger Reverse Osmosis System EG-RO 400GPD
The Eiger EG-RO-400B is a reliable professional reverse osmosis system designed for environments with increased water consumption needs, such as cafés, restaurants, hotels, offices, and commercial kitchens. Thanks to multi-stage reverse osmosis technology, the system effectively removes salts, heavy metals, chlorine, microparticles, and dissolved contaminants, delivering exceptionally pure water with improved taste. Its high performance makes it suitable for continuous professional use, while its compact design allows for easy under-counter or technical-room installation.
The EG-RO-400B significantly reduces operating costs, protects professional equipment (coffee machines, ice makers, etc.) from scale buildup, and extends the lifespan of appliances, making it a comprehensive and sustainable clean water solution.
Absolute Hygiene Without a Tank
The system’s innovation lies in its tank-less design. By eliminating the bulky water storage tank—which often becomes a breeding ground for bacteria—the risk of secondary water contamination is removed. As a result, bacteria lose their reproduction space, and every drop that reaches your glass is fresh, clean, and safe.
Ultra-Fast Water Flow
No more waiting. Thanks to the powerful electric pump and high-flow system, water flow is up to 7 times faster compared to traditional reverse osmosis systems with a storage tank.
- Traditional systems (75 GPD): Approx. 0.13 L/min
- EG-RO-400B: From 1.0 L/min up to 2.0 L/min, filling your glass instantly
70% Space Saving
The integrated and compact design (Integrated Water Way Design) saves significant space under your sink. The slim main unit, without a storage tank, saves up to 70% of space, leaving your cabinet free for other kitchen equipment.
High-Precision 4-Stage Filtration
The system ensures water purity through a 4-stage filtration system with filtration accuracy down to 0.0001 μm. It effectively removes:
- Heavy metals and dissolved solids
- Viruses and bacteria
- Chlorine and large particles, while improving water taste
The process includes a PP membrane, carbon fiber filter, reverse osmosis (RO) membrane, and a high-density PP membrane.
Efficiency and Ease of Use
- Reduced Water Waste:Clean-to-waste water ratio of 1.5:1 (high-performance models) or 1:1, saving over 200% more water compared to traditional systems.
- Easy Installation: Integrated design reduces piping connections, minimizing the risk of leaks.
- 3-Second Filter Replacement: Filter changes are quick and simple with a twist mechanism—no tools or disassembly required.
