400 GPD Reverse Osmosis System with Blend Valve, TDS Display, and Expansion Tank

Water is the foundation of great coffee. If the water is off, everything is off. This 400 gallon per day RO system gives you control, consistency, and peace of mind behind the bar.

Designed for cafés and serious coffee environments, this system produces up to 400 gallons of purified water per day, removing dissolved solids that cause scale, damage equipment, and mute flavor clarity. From there, the integrated blend valve allows you to dial your water back in. Instead of running pure zero TDS water, you can set your target mineral content and send exactly the right water profile to your espresso machine or brewer.

A built in TDS meter screen lets you confirm output in real time. No guessing. No test strips. You can see what your system is producing and adjust as needed to stay in your ideal range.

An expansion tank is included to maintain consistent pressure and flow during peak service. Tank size is selected based on your specific needs, with options ranging from 3 to 10 gallons included.

Key Features:

• 400 gallons per day production capacity

• Adjustable blend valve to set final TDS

• Digital TDS display screen for live monitoring

• 3 to 10 gallon expansion tank included

• Designed for coffee and beverage equipment

• Not compatible with ice machines

If you are investing in quality equipment, protecting it with properly balanced water is not optional. This system helps extend machine life, reduce service calls, and most importantly, support better tasting coffee every single day.
