EXCEL Gas is a leading supplier of industrial water demineralizer and deionizer (DI) equipment designed for the economical and efficient removal of dissolved salts and minerals. These water treatment systems produce high purity water for commercial and industrial applications. EXCEL Gas supplies a complete line of DI systems to meet your water quality requirements.
EXCEL Gas supplies deionizers are available as standard pre-engineered units or as custom designed systems with the flexibility to meet a wide range of requirements.

These DI water systems can be manufactured with a full range of options and related equipment to provide fully integrated water purifications systems. Tanks range in size from 14" to 48" in diameter, with flows up to 188 gallons per minute. The deionizers are a highly efficient means of removing dissolved minerals and solids to produce high purity DI water.
DI Water System Features and Benefits
EXCEL Gas supplies deionizers are designed for fully or semi-auto production of water with a conductivity of less than 10 micro-ohms and feature:
- Strong acid cation and type 1 strong base anion resins as the standard, with other resins available as an option.
- Microprocessor based control system with conductivity monitor and flow sensor for regeneration initiation.
- Electrical enclosures are NEMA 4XFG corrosion resistant fiberglass, which reduces maintenance costs.
- Resin vessels can be polyethylene-lined fiberglass or rubber-lined steel depending on size and customer requirements.
- ASME code vessels.
- Factory assembly and skid mounting for quick installation and minimum startup cost.
- Schedule 80 PVC piping package including air operated composite plastic diaphragm valves is standard. Air or electric actuated ball or butterfly valves are available as an option.
- Pressure regulators, rotameters and metering valves supplied for accurate and safe control of regeneration water and chemical introduction.
- Internal distributors are corrosion resistant, designed for optimum efficiency and are fully supported where required.
Why use a Water Demineralizer / Deionizer?
The deionization process removes ions (cations and anions), dissolved solids and gases, including:
- Sodium, calcium, and magnesium (cations)
- Sulfates, alkalinity, chlorides, carbon dioxide, and silica (anions)
Deionization is accomplished by passing water through ion exchange columns containing cation and anion resins. Simply put, the result is water without ions minerals and salts.
Applications for Industrial and Commercial DI Water Sytems
The following facilities are examples of ideal applications for water demineralizer and deionizer (DI) equipment:
- Food and Beverage Processing Plants
- Power plants
- Chemical plants
- Pharmaceuticals
- High pressure boiler feedwater
- Manufacturing Plants
Service DI versus Installed DI Systems
There are two choices when considering using the deionization process in a plant:
- Service DI (SDI)
- Installed DI
Service DI
In some instances, a company may want to consider Service Deionization, SDI, for emergency applications, temporary systems or permanent applications requiring Ultrapure Water, with a flow requirement of 1 GPM to 150 GPM. DI exchange tanks eliminate the cost and responsibility of a regenerable DI system and afford you an uninterrupted flow of UltraPure quality water.
Installed DI Systems
A company should consider an installed DI system if the demand is relatively constant, the water quality is consistent, have the training to handle chemicals and have the permits to discharge waste regenerant chemicals.
Terminology for DI Sytems
Deionizers, de-ionizers, demineralizers, and de-mineralizers are the different names for the same equipment. DI is often used as the abbreviation for De-Ionization or De-Ionizers. You will also hear this equipment called DI systems, DI water systems, DI cells, or DI water treatment systems. Two-bed deionizers are sometimes referred to as separate bed systems or mono-bed systems.
