Demineralised Water Systems
High-purity performance, tailored to your operational needs
At AllWater Technologies, our demineralised water systems are built to deliver consistent, ultra-pure water for the most demanding industrial processes. Whether you’re operating in pharmaceuticals, precision manufacturing, metal finishing, or laboratory environments, our DI water systems are engineered for reliability, efficiency, and compliance.
We offer a comprehensive selection of standard and bespoke deionisation systems, including compact DI water units for small-scale operations and large, fully automated twin-bed demineralisation water units for continuous high-flow requirements. Every system is backed by in-house design expertise and a commitment to quality that runs throughout every project we deliver.
Why Choose a Demineralised Water System?
A demineralised water system, also known as a deioniser or DI system, removes dissolved salts and ions from water using ion exchange technology. This is essential in processes where mineral contamination could interfere with production quality or cause corrosion in sensitive equipment.
AllWater Technologies supplies industrial DI water units that meet the needs of both low and high-purity applications. Our systems help clients:
- Achieve consistent water quality
- Protect sensitive equipment from scale and corrosion
- Maintain compliance with process specifications and industry standards
Reduce operating costs through efficient regeneration and automation
Our support includes
Telephone & remote diagnostics for rapid fault identification
System troubleshooting and root cause analysis
Planned service visits tailored to your production schedule
Guidance on optimisation, upgrades and retrofit options
Ongoing training and user support post-installation
On-site engineering support from qualified specialists
Our Demineralisation and Deionisation Solutions
We offer a wide range of system configurations to suit different flow rates, space requirements, and operational goals. These include:
Compact Skid-Mounted DI Units
Ideal for low-volume or space-constrained applications, our compact demineralisation water units use advanced multiport valve technology to deliver efficient service and regeneration cycles.
Key features:
- No separate source of DI water for regeneration required
- Compact and low cost
- Fully skid-mounted on a corrosion resistant polypropylene skid
- Low chemical consumption and minimal downtime
Counter-Current Demineralisation for Enhanced Efficiency
Our counter-current DI systems offer superior water quality by reversing the flow of regenerants during resin regeneration. This ensures that treated water comes into contact with the most highly regenerated resin, reducing chemical usage and increasing output quality.
Advantages:
- Fast regeneration time (typically 30 minutes)
- High quality, low conductivity treated water (typically < 2 uS/cm)
- More efficient use of regenerants
- Self-neutralising effluent stream
Larger Industrial DI Water Systems
For high-demand environments, our larger systems are constructed with individual diaphragm valves on pipework manifolds, all supported on a durable steel frame. These designs simplify maintenance and allow for greater scalability.
Typical applications:
- Power generation
- Automotive and aerospace components manufacturing
- Any industry requiring consistent high-purity water at volume
Custom Deionisation Systems
When off-the-shelf solutions won’t suffice, we can design and manufacture bespoke deionisation systems tailored to your site, process, and water quality requirements.
Custom features may include:
- Specialised ion exchange resins for specific contaminants
- Resin cleaning systems (in situ or offline)
- Integrated recovery solutions for rinse water recycling
- Compact or modular builds to suit restricted footprints
- Custom valve configurations and chemical dosing systems
We’ve developed specialist DI pure water systems for clients in the metal finishing, electronics, and life sciences sectors—each with industry-specific adaptations and long-term performance guarantees.
All DI water systems from AllWater Technologies are available with modern control options to simplify operations and improve reliability.
Options include:
- Conductivity or resistivity monitoring for real-time quality assurance
- PLCs for automated process control
- HMIs for intuitive local system operation
- Remote diagnostics and fault alerts
- Data logging and performance tracking
These features help you stay compliant, reduce manual oversight, and spot issues before they affect output.
To ensure safe and compliant chemical management, we provide a full range of regenerant storage and fume scrubbing systems tailored to your plant’s footprint and volume.
Solutions include:
- Semi-bulk and bulk chemical storage tanks
- Day tanks and carboy stations
- Resin-type scrubbers with colour-change media for visible performance
- Integrated transfer pumps and containment bunds
We work closely with you to match these elements to your safety protocols and chemical usage needs.
Every DI system we build is designed, fabricated, and tested at our UK facility. This means:
- Complete oversight of quality from design to delivery
- Client sign-off available at any stage of the build
- Rapid turnaround on replacements, upgrades, and parts
- Ongoing support from the engineers who built your system
We understand that specifying the right DI water unit can be complex. Our team offers expert consultation to help you evaluate:
- Feedwater quality and flow requirements
- Space and installation constraints
- Output purity and regulatory standards
- Maintenance and regeneration preferences
We’ll work with you to recommend a solution that matches your goals—whether that’s a compact deioniser system or a fully automated industrial reverse osmosis and DI hybrid plant.

Frequently Asked Questions (FAQ)
A demineralised water system removes dissolved salts and minerals from water through ion exchange. It is commonly used where ultra-pure water is required for industrial processes.
Reverse osmosis removes most contaminants using a semi-permeable membrane, while DI systems remove remaining ions for higher purity. They are often used in combination.
This depends on your flow rate, space, and water quality requirements. We offer both compact units and large-scale twin-bed systems with custom options.
Yes. AllWater Technologies can tailor your system with specialised resins, automation features, compact layouts, and more.
Absolutely. We offer full commissioning, service agreements, and emergency support to ensure your system operates reliably over the long term.
