3M™ commercial reverse osmosis scale reduction system for coffee, hot tea and espresso, Model TFS450 RO helps produce consistent Recipe Quality Water™ for hot beverages and steamers while maintaining efficient equipment operations in water conditions with high total dissolved solids (TDS) and/or hardness.

• Precision lockable, metering valve provides Recipe Quality Water™ with adjustable Total Dissolved Solids (TDS)* for coffee and espresso brewing
• Reduced equipment maintenance and replacement costs from reduced minerals that cause lime scale
• Daily production from 300 gallons/day (1136 liters/day) with no blending up to 600 gallons/day (2271 liters/day) with blending**
• Conversion of inlet water to product water (water utilization efficiency) is at least 50%; higher with blending**
• Lower product-water recovery times with use of the included permeate pump
• A hydraulic (non-electrical) bypass valve maintains the water flow in high demand situations
• All product water (including blending and bypass) is pre- and post-filtered by carbon and particulate filters for cyst reduction and great taste
• System includes built-in pressure gauges and an in-line product-water TDS meter for monitoring
• Sanitary Quick Change (SQC) encapsulated cartridge design allows for fast and easy cartridge change-outs
• System includes pre-filter, (Model HF90), post filter, (Model HF95) and (2) RO Membranes, (Model CFS M)
• Requires external storage tank (not included)

Scale can cause equipment down time, reduces energy efficiency, and affects both water-level and temperature controls. The design of our TFS450 System allows for filtered water to be blended with RO water for adjustment of beverage quality and production volumes to about 300 gal/day**. On-line TDS monitoring and pressure gauges are included. An installation kit is available (sold separately).

"* From 10% to about 50% of inlet-water TDS
**Capacity/Conversion is at 77 °F (25 °C) and 70 psi feedwater pressure to atmosphere without blending. With blending the system production rate is approximately doubled and the maximum outlet water Total Dissolved Solids (TDS) is about 50% of inlet water TDS. Performance may vary depending on water temperature and pressure."
