DEMI Set with ion-exchange resin MB20 ROHM HAAS for complete demineralization of water. Recommended as the final stage after the RO reverse osmosis filter, especially in marine aquaristics. The set includes a 10" housing with a 1/4" connection, a disassemblable canister for multiple refills, resin (pre-filled), fittings, clips, tubing, and mounting components.
Demineralization set water resin MB20 is a complete final-stage cartridge for a water treatment system, designed to operate after a reverse osmosis filter. This stage perfectly complements a reverse osmosis system and helps achieve water with a very high degree of purity, especially where full demineralization matters, such as in marine aquaristics. The ready-to-install set includes a 10" housing, a refillable canister for repeated media filling, MB20 resin, fittings, clips, tubing, and mounting components, making it a practical solution as a final water filter working with an RO installation.

The DEMI set with ROHM HAAS MB20 ion exchange resin has been prepared for complete water demineralization after prior purification in an RO system. It is used as the final stage of filtration when standard reverse osmosis is to be supplemented with additional removal of residual ions from the water.
This application is especially valued in marine aquaristics, where the quality of the input water has a direct impact on parameter stability and the safety of the aquatic environment. The set can therefore be an important component wherever the water filtration system is intended to provide the highest possible final purity.
The set has been designed to operate as a final stage after water filtration through an RO osmotic filter. In practice, this means installation after the reverse osmosis system in order to refine the final water quality before further use.
This solution works especially well wherever water purified as much as possible from residual minerals is needed. In particular, the set is recommended for aquarium applications, especially marine aquaristics.
The DEMI set is used as the final stage after an RO reverse osmosis filter. To maintain demineralization effectiveness, the condition of the media should be monitored and the canister should be replaced or refilled when the resin no longer provides the expected performance.
The set includes all the basic components needed to connect and use the demineralization system:
The transparent housing and transparent canister make it easier to inspect the operating components and ensure proper installation of the set. The use of a refillable 10" canister is a practical solution for users who want to refill the media in the future without having to replace the entire housing.
The included wrench for unscrewing improves service handling, and the bracket for hanging the housing helps ensure stable installation. The 1/4" elbow fittings with quick connector and the 2 m length of tubing make it easy to integrate the set into an existing reverse osmosis filter or another RO system based on standard 1/4" connections.

The set is used for final water demineralization after filtration in an RO system. Its task is to further purify the water after reverse osmosis and remove residual mineral compounds that may still be present after the osmotic membrane has operated.
Yes, this solution is especially recommended for marine aquaristics, where very high water purity is important for preparing water for further use.
The set is installed as the final stage after purification with an RO osmotic filter. This means it operates after the reverse osmosis system as an additional stage of water treatment.
The set includes: a 10" transparent housing with 1/4" thread, a 10" transparent refillable canister, 0.75 L of MB20 resin filled into the canister, a wrench for unscrewing, a single bracket for hanging the housing, 2 1/4" elbow fittings with quick connector, 2 safety clips, 2 m of tubing, and a mounting plate.
Yes, the set includes a refillable 10" canister that allows repeated media filling. This is a practical solution that facilitates later operation and servicing.
The set includes 2 1/4" elbow fittings with quick connector, intended for connecting standard 6.4 mm tubing. Thanks to this, the set can be easily integrated into many popular RO installations.
Yes, the set includes 0.75 L of MB20 resin already filled into the canister. This makes installation easier and shortens the time needed to prepare the system for operation.
Yes, the set includes a wrench for unscrewing, a single bracket for hanging the housing, a mounting plate, fittings, safety clips, and tubing, which makes installation of the entire system easier.
