BRS 4 Stage Systems are perfect for reefers who have water treated with chlorine or relatively clean well water. The 4 stage systems are self-contained on a single bracket making them ideal for tight spaces or where a non-permanent connection may be required. Installing a RO/DI system only takes a few minutes and can be done very easily without any permanent modifications to your home or the plumbing.
