Designed to produce low dissolved solids water from tap or well water, these RO systems use high efficiency reverse osmosis membranes. The 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.

Part of the L-series family (other systems include XL and HL series), these RO systems are designed to work at pressures of 200-250 psi for higher TDS water and use TW reverse osmosis membranes. The TW RO membranes offer higher salt removal and the higher operating pressure overcomes the loss of membrane flow due to higher TDS level.

These reverse osmosis systems use the proven, reliable components and are mounted on a sturdy powder-coated metal frame. 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.

Wall Mount Filter Cartridges

Includes mounting bracket and Isolation Valves to close the line when changing the filter cartridge. 

Part # A711  
 

Filter cartridge must be ordered separately - common options are shown below.  Any 20" Big Blue size cartridge can be installed.  Click here to view our complete filter cartridge product selection.

Chemical Injection System

Antiscalant injection as an alternative to a water softener for scale control, or

Sodium Metabisulfite injection as an alternative to a carbon filter to remove chlorine.

Water Quality Monitors

Pre-packaged wall-mountable water quality monitoring controls allow you to monitor the quality of the incoming feed or RO product water.  Assembly includes the monitor, enclosure and sensor. 
 

• All dimensions and weights are approximate.
   
• Capacity Basis: 24 hrs/day
   
• Systems rated at: 77°F (25°C) using 1000 ppm sodium chloride solution operating at approx. 200 psi (14 kg/cm²) pressure. For feed water with higher TDS refer to our Series HL brochure.
   
• Minimum feed pressure to RO System:  40-60 PSI. System capacity changes significantly with water temperature
   
• Chlorine must be removed if present in feed water prior to RO with a carbon filter.
   
• Pretreatment for water hardness using a softener 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.
