The reusable cartridge is designed for full demineralisation and contains mixed-bed resin. For the connection of the reusable cartridge, we recommend using GENO-therm® hoses. The reusable cartridge features an integrated non-return valve and a flow stabiliser which prevents incorrect operation. The mixed-bed resin in the reusable cartridges may be regenerated. The regeneration can either be done by Grünbeck’s customer service/authorised service company or an approved specialist company.
