XL Series – Low Energy 2,000 to 10,000 GPD

XL SERIES – LOW ENERGY RO SYSTEMS 2,000 TO 10,000 GPD

Designed to produce low dissolved solids water from tap or well water, these small commercial Low Energy RO systems use extra low energy XLE reverse osmosis membranes which run at 100-140 psi. 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 L and HL series), these complete reverse osmosis systems are best suited for water of less than 1,000 PPM total dissolved solids (TDS). The systems use 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 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 1,000 ppm sodium chloride solution operating at approx. 200 psi pressure. System capacity changes significantly with water temperature. For higher TDS a water analysis must be supplied and could result in modifications to the system or changing from XL to L or HL series system.
Minimum feed pressure to RO System: 40-60 PSI.
Chlorine must be removed with a carbon filter or with chemical injection prior to the RO system, if present in feed water.
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.
Voltage Codes: 216 = 220 -240v/ 1ph/ 60hz • 215 = 220-240v/1ph/50hz .
Three phase or other voltages not available with XL Series. See Series L or HL.
