K Series Industrial

AMI Commercial Industrial RO Systems for Water Filtration

Designed to produce low dissolved solids water from tap or well water, these industrial RO systems use high efficiency reverse osmosis membranes. The product water is used in applications such as semiconductor, boiler feed, pharmaceutical, municipal, water reuse, food processing, bottling, plants, and a wide variety of other applications.

The AMI K Series reverse osmosis 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 water filtration systems. Our process and fluid design ensures an optimum membrane life and minimizes the membrane fouling.

Series K systems use 8” Diameter, 40” long membrane elements. Pressure vessels contain multiple elements and are mounted in a horizontal position.

  • Over 40 years of experience in reflected in our quality
  • Manufactured in the USA in our ISO 9001:2015 Certified Facilities
  • Conservatively engineered for reliable, long term performance
  • Factory tested to ensure trouble-free operation
  • Heavy duty powder coated frame
  • Stainless steel high pressure components, stainless steel pump
  • Microprocessor controlled operation

Notes and Voltage/ Ordering Information

  • Systems rated at 77°F (25°C) using 2000 ppm feed water and approx. 225 psi (16 kg/cm²) pressure. System capacity changes significantly with water temperature and feed TDS. For higher TDS, a water analysis must be supplied and could result in modifications to the system.
  • Chlorine must be removed with a carbon filter or with chemical injection prior to the RO System, if present in the feed water.
  • Water must be pretreated by softener or antiscalant to avoid scaling the membranes.
    All dimensions and weights are approximate.

Please add our voltage codes to the end of the model number when ordering: 
Example: J-84B-236 = 220/230v/3 ph/60 Hz
