High Quality Water for Specialized Applications

Culligan® Portable Exchange Deionizers (PEDI) are a part of a multiple process treatment system that produces high-purity water required for many specialized applications. Portable Exchange Deionizers from Culligan® is a safe, convenient and economical way to obtain consistent high-purity water from potable water sources. Our reliable PEDI systems consist of activated carbon and a selection of high quality ion exchange resins in portable exchange tanks. They connect directly to your tap water supply or for polishing to RO for high-purity water production. When the PEDI tanks are exhausted, a Culligan® service technician delivers, exchanges and maintains the equipment, thus providing continuous and uninterrupted supply of high-purity water to your operation.

Culligan® High Purity Water Advantages

Culligan® High-Purity Water Advantages

N/A No Capital Investment
You rent instead of buy and conserve your capital. Rental fees are part of your operating costs, spread out over the time you use the service. Rental charges can be arranged to suit your needs - per tank, per gallon, or per regeneration.

Reduce Labor and Maintenance Costs
There is no equipment to operate, repair and no equipment downtime. Your local Culligan® dealer installs and maintains the equipment. System regenerations are handled off site by a Culligan® regeneration facility. Your personnel do not need to handle chemicals, dispose of any waste or perform any routine maintenance or service work.

Culligan® Global Network - Global Scope, Local Service and Knowledge
With over 800 plus dealers and international licensees in over 90 countries, your local Culligan® dealer can provide quick, professional and efficient services and knowledge to address your water treatment requirements.

Culligan® Designed Regeneration Process Ensures Consistent Quality
Culligan® dealers use proprietary regeneration systems for maximum quality, efficiency and economy in resin regeneration and fast turnaround of PEDI tanks. This type of systems provide strict Quality Control processes, sanitization of each service unit, document control and tank and resin traceability.

Designed Just for You!
Our engineers work with you to determine what system configuration and design is best for your current and future needs. The system is designed based on your feed water quality, flow rate, product water quality requirements and application. Your Culligan® dealer can also provide water treatment systems such as filtration, softening, RO, sterilization and other accessories to meet your particular water treatment needs.

Advanced Monitoring and Control Capabilities with the Culligan® Smart Controller
The exclusive Culligan® GBE Smart Controller monitors and control the functions of your PEDI system including: current flow rate, daily usage, total usage since new, monitor water quality, auto bank switching, remote monitoring capabilities.

High Purity Water System from a Single Tank to a Complete Solution

High-Purity Water System from a Single Tank to a Complete Solution

N/A Culligan® PEDI High-Purity water systems are available in several system configurations. Your system is customized for size, capacity, system configuration to help meet your water quality and quantity needs in the most efficient and economical operation.

Two-Bed Portable Exchange Deionizer (PEDI) System

Two-Bed Portable Exchange Deionizer (PEDI) System

N/A This is a typical Ion Exchange DI System where the Cation and Anion Exchangers are connected in series as two separate columns. The Cation column/tank reduces positively charged ions (calcium, sodium, magnesium, potassium, iron, etc). The Anion column/tank reduces negatively charged ions (sulfates, chlorides, carbonates, bicarbonates, nitrate and silica). Strong Base Anion units typically produce deionized water with quality of <0.5 megaohms-cm at a pH of 8-9. Weak Base Anion units produce lower quality water (50 kohms-cm nominal), at pH of 6-7, and do not remove silica and CO2.

N/A Cation and Anion resins are combined typically in a 40/60 by volume proportion and mixed in a single column/tank. Mixed Bed Deionizers are used in the production of High-Purity water of >2 megohms-cm resistivity with a more neutral pH than two-bed systems. Typical installation includes two columns in series (worker - polisher) to provide continuous High-Purity water and back up contingency. Mixed Bed PEDI is used with tap water or as polishing systems downstream from RO water purifiers for the production of ultrapure water of >10 megohms-cm. Up to 18.2 megaohms-cm ultrapure water can be produced.

Multiple-Tank Portable Exchange Deionizer (PEDI) Systems

Multiple-Tank Portable Exchange Deionizer (PEDI) Systems

N/A Three tanks or more are connected in series or parallel or a combination of the two. Produces High-Purity water in any desired quantity. Systems typically consist of a Strong Acid Cation (SAC) column, a Strong Base Anion (SBA) and a Mixed Bed (MB) Polisher column in a number of varying combinations to produce the water quality and quantity required. High-purity water quality of >15 Megaohms-cm, with a more neutral pH can be attained.
