Advanced EDI technology for the industries that cannot compromise on water quality
The E-Cell™ EDI MK-5D Stack delivers a continuous, chemical-free solution for producing ultrapure water in demanding industrial applications. Designed for power generation, solar manufacturing, green hydrogen, semiconductor production, and other heavy industries, it combines outstanding water quality with low energy consumption and dependable, long-term operation.
Using electrical current to continuously regenerate ion exchange media, the MK-5D eliminates the need for acid or caustic regeneration, brine injection, or concentrate recirculation. The result is a cleaner, simpler, and more efficient approach to ultrapure water production.
Built for Consistent Ultrapure Water
With advanced electrodeionization technology and flexible counter-current operation, the E-Cell™ EDI MK-5D Stack is engineered to maintain high product water quality while reducing operational complexity.
Key performance highlights
Product water resistivity of up to ≥16 MΩ·cm
Sodium levels of ≤3 ppb
Silica levels as low as 5 ppb
Boron levels as low as 0.08 ppb
Sodium removal of ≥99.9%
Silica removal of up to 99%
Boron removal of up to 96%
Recovery of up to 97%
Continuous operation without chemical regeneration
No brine injection or concentrate recirculation required
Standard 3-year prorated warranty for leak-free operation
Actual performance depends on feed water quality, system configuration, operating conditions, and site-specific requirements. Performance guarantees are available for qualified design conditions.
Designed for Demanding Industrial Applications
The E-Cell™ EDI MK-5D Stack provides reliable ultrapure water for applications where quality, uptime, and operating efficiency are critical.
Typical applications
Ultrapure rinse water for semiconductor chips, solar panels, and microelectronics
Demineralized boiler feed water for high-pressure boilers
Ultrapure water for electrolyzer-based green hydrogen production
High-purity process water for power generation and other heavy industries
From high-pressure steam systems to next-generation hydrogen production, the MK-5D helps support stable operations and stringent water quality requirements.
Lower Chemical Demand. Simpler Operation.
The MK-5D Stack continuously regenerates its internal ion exchange media using electrical current. This eliminates the routine handling and storage of regeneration chemicals while helping simplify system design and reduce chemical consumption.
Operational advantages
Continuous production of ultrapure water
No acid or caustic regeneration
No brine injection
No concentrate recirculation
Reduced cleaning requirements at higher feed water hardness levels with counter-current operation
Compact design for efficient system integration
Reliable performance with minimal operator intervention
Flexible Performance for Real-World System Design
