Culligan’s demin water systems
Guaranteed and continuous supply of demineralized water
The creation of demineralized water is achieved by means of a deionization process. Our deionizers program can be used as stand-alone units for small water applications such as laboratories or for the production of demineralized water within the industry. For the treatment of larger water flows, we use our deionizers in combination with our reverse osmosis technologies, which provide a downstream polishing phase to supply pure demineralized water in a cost-efficient manner.
Our deionizers use ion exchange resins. As an alternative to small water flows, our portable exchange detergents (PEDI) offer a low-cost alternative with service options, including our experienced technicians who can replace depleted resins to keep your system operational.
- Culligan Continuous Electro-deionization (CEDI) systems (flow ratio till 15 m³/hour)
CEDI process reduces ions from water using electricity, resin and membranes, decreasing the need for chemicals. CEDI is used as a polishing process to further deionise Reverse Osmosis permeate to multi megaohm-cm quality water. Models are available for up to 13m³/hr flow rate.
- Culligan Automatic Deionisation Systems (flow ratio till 40 m³/hour)
Fully automated demineralisation units designed for flows up to 40m3/hr. Choose from a flexible configuration of weak base or strong base resin tanks. Deyolit series deionizers are equiped with a control system designed to monitor the process & automatically initiate regeneration when water quality deteriorates to a pre-determined limit.
- Culligan PEDI Portable Exchange Deionizers (flow ratio till 3 m³/hour)
For installations where regeneration systems are not appropriate, replaceable portable exchange deionisers (PEDI) are an great solution. Suitable for a wide range of flow rates (up to 500 L/hr), Culligan PEDI systems reduce both positively and negatively charged ions from water by means of ion exchange resins. When your PEDI tanks are exhausted, a Culligan service technician can replace your ion exchange tanks at your convenience. This type of system can reduce capital costs as well as handling of regenerate chemicals such as caustic and acids.
