Spectrum SPECTRUM SRDI-IND ION-X Purity Colour Change 20" Large Diameter
The SPECTRUM Ion-X high purity colour change DI cartridge has been designed specifically to provide demineralised water for applications requiring high purity water for washing, rinsing and testing purposes with resistivity in excess of 10 megohm.As the cartridge will visually change colour over the course of its life to indicate exhaustion, it is ideal for applications that have been designed without flow meters. To ensure a constant supply of high purity water, two cartridges can be used in conjunction where the first is put into the ‘roughing position’ and the second into the ‘polishing position’. This ensures complete utilization of all the exchange capacity thereby lowering operating costs while increasing average quality.Maximum Temperature: 37°CFeatures & Information Colour change resin beads throughout the media give visual indication as the media becomes exhausted (from purple to light brown) Achieves resistivity levels to 10 megohm, ideal for washing, rinsing and testing purposes Features & Information Laboratories Corrosive test chambers Dentistry

Pentair Pentair RFFE10-BB Iron Removal Large Diameter Cartridge, 10"
The RFFE from Pentair helps to eliminate the orange and brown stains often found in sinks, toilets, baths and other plumbing fixtures, as well as reducing the possibility of damage to pipes and water heaters and is effective where feed concentrations are up to 3 ppm dissolved iron.Completely suited to drinking water applications, cartridges should be installed on the main cold water line after the pressure tank or water meter. For best results, pre-sediment (SSP-5) and post carbon (RFC20) treatment is recommended. As water flows through the cartridge the RFFE causes the iron to oxidize and drop out of the flow, holding it within its matrix to ensure no harmful chemicals are added to the water.Recommended Operating Conditions:pH: >7.0Silica: <100 ppmManganese: <1 ppmIron: <3 ppmIron Bacteria: NoneHydrogen Sulphide: NoneMax flow rate: 12 lpmMaximum Temperature: 37°CFeatures & Information Easily and effectively reduces up to 3 ppm of dissolved iron from water Improves flavour and reduces the metallic taste caused by iron Reduces the possibility of pipe and water heater damage For use in Pentek 10- and 20-inch Big Blue filter housings
