Everpure EV9973-65 MRS-350CC-BL 350 GPD Reverse Osmosis System with Remineralization and Blending Valve Overview

The Everpure EV9973-65 MRS-350CC-BL reverse osmosis system is designed to protect espresso and coffee equipment by delivering highly purified, balanced water. Using advanced reverse osmosis technology, it removes at least 90% of total dissolved solids (TDS), helping prevent limescale buildup that can reduce performance and damage internal components.

By also reducing chlorine, taste, odor, and particulates, this system ensures consistent water quality that enhances beverage flavor while lowering maintenance costs and extending equipment lifespan.

Design

Engineered for precision and flexibility, this system includes a calcite feeder cartridge that reintroduces a controlled level of minerals into the water. This re-mineralization is ideal for espresso applications where balanced water chemistry is essential for optimal extraction.

A built-in blend valve allows operators to fine-tune the mix of purified RO water and filtered water, creating a customized water profile while improving system efficiency. The unit is designed for wall mounting with easy service access, requiring clearance around all sides for maintenance.
