Chemical-free, waste-free ion exchange system

With cartridge water purifiers, resin replacement is required once the ion exchange resin capacity is exhausted. We collect the ion exchange resins and perform the chemical-based cleaning work, so you don’t have to worry about cleaning or waste disposal. When replacing the resins, we perform ion exchange resin quality testing and cylinder pressure testing based on our own inspection standards prior to delivery.
