The CWS-100 is a durable compact and portable spot free, water purification system engineered to process up to 39,000 gallons of water and produces ultralow TDS spot free water before having to replace the carbon block filter at minimal cost. The life expectancy of the membrane element is 3 to 5 years when recommended maintenance is followed.

The production capacity ranges up to 2500 gallons per day, depending on incoming water pressure. Our compact portable design allows for ease of mobility and can be connected to a water storage tank and then used in conjunction with a pressure washer as needed.

The CWS-100, spot free water system operates off normal tap water pressure and filters water by reverse osmosis and does not use Deionization (DI). Reverse Osmosis water is the least expensive to produce per gallon, and leaves the best looking surface as opposed to DI, which can dissolve waxes, etch or corrode metal surfaces, and cloud paint jobs. This product is excellent for professional spot-free window and solar panel cleaning, automotive, marine and aviation detailing and car wash use.  Surfaces dry spot free without hand drying. Simply attach a garden hose and you are ready to produce 100% spot free water.
