Wall Mount High TDS Series

AMI Wall Mount High TDS Reverse Osmosis System

Designed to produce low dissolved solids water from high TDS tap or well water, these wall-mountable RO systems use high efficiency reverse osmosis membranes. The RO product water is used in applications such as spot free rinse, water stores, whole house, labs, ice makers, humidification, misting and a wide variety of other applications.

The convenient, space efficient wall mountable reverse osmosis systems are substantially lower in cost than frame-mounted RO systems and are more cost-effective to ship.
WMH Series RO systems are expandable to allow for quick, easy and cost effective upgrades to systems in the field. Simply purchase and install the appropriate expansion kit assembly to increase your system capacity at any time down the road.
These reverse osmosis systems use the proven, reliable components and are mounted on a sturdy powder-coated metal mounting backplate. There are numerous design details learned from years of experience that are incorporated in our water filtration systems. Our process and fluid design ensures an optimum membrane life and minimizes the membrane fouling.

Notes and Voltage/ Ordering Information

All dimensions and weights are approximate.
Capacity Basis: 24 hrs/day
Systems rated at: 77°F (25°C) using 5000 ppm sodium chloride solution operating at approx. 200-250 psi pressure.
Minimum feed pressure to RO System:40-60 PSI. System capacity changes significantly with water temperature
Chlorine must be removed with a carbon filter prior to the RO system, if present in the feed water.
Pretreatment for water hardness using a softener or antiscalant injection should be added to avoid scaling the membranes.
Feed water turbidity: Less than 1 NTU; Feed water silt density index (SDI): 3 maximum. If exceeded, pretreatment with media filter recommended. All pretreatment equipment and SDI test kits are available from Applied Membranes.

Voltage Codes: Above models indicate recommended voltage codes per model.

Available voltages:

• 116 = 120V/1ph/60hz • 215 = 220V/1ph/50hz.
• 216 = 220 or 230V/ 1ph/ 60hz • Three phase not available.
