arium® 615DI cartridges are designed to produce highly deionized water. The DI cartridges contain highly effective ion exchange resins to remove cations and anions from the water by exchanging H+ and OH–. The uniform and compact mixed bed ensures a reliable desalination and an optimal utilization of the resin material, reducing conductivity by up to 0.1 µS/cm. All DI cartridges are available in three different types (with LED or digital controlled conductivity monitoring and without conductivity monitoring), producing 10 l/min, 18 l/min and 25 l/min.The LED controlled 615DIL cartridges allows the user to monitor the conductivity of the product water with a red or green light. If the conductivity is 20 µS/cm, the LED lights up green. If the conductivity is > 20 µS/cm, the LED lights up red, to alert the user.The digitally controlled 615DIC cartridges allow the user to monitor the conductivity by individual adjustable alarm requirements. The conductivity measurement range is between 0.1–200 µS/cm.
