DI Resin Cartridge 10" Color Changing

ResinTech MBD-30 is a 1:1 volumetric mixture of CG8-H (an amber-colored hydrogen form cation resin) and SBG1P-OH-ID (a dyed hydroxide form type 1 porous strong base anion resin). The anion component is infused with a permanent pH indicator dye that changes color from blue to amber as the resin exhausts. MBD-30 is intended for use in cartridge applications where a color indication of resin exhaustion is desired.

Many manufacturing processes require high purity water for washing, rinsing and test purposes. Not all processes requiring demineralized water need the ultimate quality; however, they may require multi-megohm resistivity water. MBD-30 is designed to provide demineralized water with a resistivity in excess of 18.3 megohm. It is specially intended for use in cartridge applications with clear (see-through) housings. Such systems are typically designed without meters and rely on the changing color of the mixed bed resin to indicate exhaustion. In typical operation there is a safety line at the exit end of the cartridge, and when the color change reaches that level, the cartridge is considered exhausted and exchanged for a fresh cartridge. Our DI resin is rated for 6,800 ppm tds per 10" cartridge, with a minimum of 3,000 ppm tds holding capacity across almost all water profile types.
