RObust COFFEE direct flow reverse osmosis filter offers a unique solution for coffee professionals. Designed in compliance with global coffee standards, it provides water that enhances the unique taste of coffee. The water meets Specialty Coffee Association standards.
Enjoy perfect coffee with a simple RObust setup
RObust COFFEE filter system is designed to provide perfectly balanced water for brewing high-quality coffee. Through a combination of advanced purification stages and mineral enrichment, it ensures optimal water composition that meets SCA (Specialty Coffee Association) standards. Here's how the filtration process unfolds:
1. Pre-filtration:
Tap water undergoes initial treatment to remove mechanical impurities, chlorine, chlorinated organic compounds, and natural organic substances, preparing it for the next stages.
2. Membrane filtration (Ecosoft RO element):
Water is pushed through a semi-permeable reverse osmosis membrane, which removes up to 99.8% of dissolved impurities, including viruses and bacteria. The membrane's pores are 200 times smaller than viruses and 4000 times smaller than bacteria, ensuring exceptional purification.
3. Special coffee cartridge:
Water flows through a dedicated cartridge that enriches it with calcium (Ca) and magnesium (Mg). These minerals enhance the extraction of flavor and aromatic components, delivering premium-quality coffee.
4. Post-carbon filtration:
Water undergoes final polishing to improve its taste and aroma by removing any residual odors.
High-pressure pump system:
A high-pressure pump feeds water simultaneously to the membrane and the special coffee cartridge. The result is water enriched with Ca and Mg in concentrations aligned with SCA (Specialty Coffee Association) recommendations.
Dry-run protection:
If the water supply is interrupted or the inlet pressure drops below 0.4 bar, a low-pressure relay automatically shuts off the valve and disables the pump. Even if the purified water faucet remains open, the system won't restart until the necessary inlet pressure is restored, safeguarding the pump from damage.

RObust COFFEE direct flow reverse osmosis filter is designed for cold tap water only.
The front panel features two pressure gauges:
- Inlet pressure gauge: shows pressure after pre-filters.
- Pump pressure gauge: shows pressure after the membrane block.
If pressure drops below recommended levels, follow the panel instructions.
Pre-filtration cartridges
Replace after filtering 5,000 liters or at least every 3 months. Delayed replacement may damage the membrane.
Reverse osmosis membrane
Replace after filtering 40,000 liters or at least once per year if filtration speed decreases.
Post-filtration cartridge
Replace if taste deteriorates or odor appears, after 5,000 liters or at least every 3 months.
Replace all cartridges together as a set.
Downtime maintenance
If unused for over 2 weeks, disinfect before resuming use (procedure in the user manual).
Compatible replacement solutions
Perfect water for better coffee
Enjoy coffee made with water that meets the Specialty Coffee Association standards, with a Total Dissolved Solids (TDS) range of 60-120 ppm for pure water quality. This enhances the taste and aroma, providing a premium coffee experience every time.
Economical and environmentally conscious
With a 1:1 Pure to Drain ratio, the RObust COFFEE minimizes water waste and enhances cost efficiency, saving up to 350 EURO per year by converting a significant portion of water into purified output.
Built-in pressure monitoring
Equipped with pressure gauges, the system continuously monitors pump conditions. This ensures stable performance and helps identify maintenance needs before they become critical, enhancing the longevity of the system.
Reliable flow for consistent brewing
The filter provides a steady supply of 75 liters per hour, enough to keep your coffee machine running smoothly throughout the day, even during busy hours.
Customizable water quality
The system offers flexibility to adjust based on the specific TDS levels of your feed water, allowing for precise calibration to suit your water's unique composition. This adaptability ensures the filter consistently delivers high-quality water, effectively reducing impurities and maintaining performance, even in regions with fluctuating TDS levels.
Certified safety and compliance
RObust COFFEE system is CE-marked, confirming its compliance with European safety standards. It is also certified under EC New Approach Directives, providing peace of mind regarding its safe operation.
