A five pound bag of mixed bed DI resin for spot free water. This is enough resin to refill (4 +) 10 inch filters. This is a mixed bed - both cation and anion resins are combined in this one bag. The resin is color changing.
We also offer bulk Anion and bulk Cation resins. These are also color changing.
This is enough for 4 refills of our refillable Clear Canister
RESINTECH MBD-30 is a self indicating
mixed bed resin. It is a mix 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 blue to colorless 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 blue color to a very
light 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.
RESINTECH 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. The actual quality
that is obtained depends on the manner in which the cartridge is configured. A constant supply of high purity water can be obtained
by using two cartridges in series, and allowing the
first cartridge to completely change color. During this operation the second cartridge
insures that the water leaving the system is of the
highest purity. New cartridges are placed into the polishing position and the remaining cartridge is moved to take the place of the first.
