K Series Industrial
K-Series Commercial & Industrial RO Systems
Designed to produce low dissolved solids water from tap or well water, these industrial-grade RO systems use high-efficiency reverse osmosis membranes for reliable, long-term performance.
Applications include semiconductor manufacturing, boiler feed water, pharmaceutical production, municipal water treatment, water reuse, food and beverage processing, bottling plants, and more.
The AMI K-Series RO systems are built using proven, reliable components and mounted on sturdy powder-coated steel frames. Years of design experience are incorporated to ensure ease of maintenance and performance optimization.
Series K systems utilize 8” diameter, 40” long RO membrane elements. Pressure vessels are mounted horizontally and contain multiple elements per vessel for high-volume throughput.

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
