DI Resin Cartridge 10" Color Changing

This single DI Cartridge is made from MBD-30 is a self indicating mixed bed resin. It is a mixture of nuclear grade hydrogen and hydroxide form resins. The anion resin is a Type I strongly basic gel resin with an indicator dye that changes from greenish blue to rusty brown as the resin exhausts.

The cation component is a strong acid sulfonated polystyrene gel type cation exchange resin. During exhaustion, as the indicator dye changes color, the appearance of the mixed bed changes from a green color to a brown color. 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 10 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. The actual quality that is obtained depends on the manner in which the car
