  • 4500 Gallons Per Day (17 cubic meters per day) Heavy-Duty Commercial Reverse Osmosis System: produces high quality purified water by reverse osmosis thin film (TFC) membrane using a high pressure pump (included).
  • Removes total dissolved solids; chlorides; sodium; boron; fluoride; minerals and other salts using high-rejection high quality thin-film reverse osmosis membranes.
  • Unlike light-duty systems this reverse osmosis unit includes a 1.0 HP heavy-duty stainless steel multistage centrifugal pump ensuring long life and better performance than standard rotary vane pumps.
  • The unit comes with a white powder-coated steel frame; stainless steel braided hoses; inlet solenoid valve; and stainless steel concentrate control valve.
  • To make service and operation easier this unit includes many options not normally included in other base-unit reverse osmosis systems such as: 5-micron pre-filter; pure-water (permeate) flow meter; waste-water (concentrate) flow meter; PVC pressure vessels; and automatic feed-water shut-off valve.
  • The pressure gauges included display pressure for the high pressure pump; inlet water pressure and pre-filter outlet; making it easy to diagnose and track pressure across the pre-filter.
  • An excellent control panel package includes a UL listed control box with On/Off Switch; low-inlet water protection; function LEDs; and contacts to set up float switches in a storage tank.
  • The control box also features contacts for locking out pretreatment filters during backwash and makes it easy to connect anti-scalant pumps.
