Overview
The Deepflow CYTTED150 EDI Module is an electrodialysis ion exchange unit engineered for continuous, chemical-free polishing of purified water to ultrapure specifications. Integrated into multi-stage ultra-pure water systems, it operates on the principle of electrochemical deionization—using direct current across ion-selective membranes and mixed-bed ion exchange resins to remove residual ionic contaminants from reverse osmosis (RO) permeate. Unlike traditional mixed-bed polishing, the CYTTED150 eliminates the need for periodic acid-base regeneration, enabling uninterrupted operation with stable resistivity ≥18.2 MΩ·cm at 25 °C and total organic carbon (TOC) <5 ppb. Designed for laboratory-scale and pilot-system deployment, it delivers a nominal throughput of 150 liters per hour under standard feedwater conditions (conductivity ≤10 µS/cm, silica <0.5 mg/L, temperature 15–35 °C), meeting ASTM D1193 Type I and ISO 3696 Grade 1 water quality requirements.
Key Features
- Continuous electrochemical deionization without chemical regeneration—reducing operational risk and waste disposal burden
- Integrated stack architecture with homogeneous ion-exchange membranes and optimized resin packing for high current efficiency and low energy consumption
- Stainless steel 316L housing with sanitary tri-clamp (DIN 11851) inlet/outlet ports for seamless integration into existing water distribution loops
- Real-time monitoring of key performance indicators: module voltage, current draw, product water resistivity, and feed conductivity via optional analog 4–20 mA outputs
- Modular footprint (W × D × H: 420 × 380 × 650 mm) compatible with skid-mounted or cabinet-integrated system layouts
- Compliance-ready design supporting IQ/OQ documentation packages and traceable component certification (CE, RoHS)
Sample Compatibility & Compliance
The CYTTED150 is intended exclusively for post-RO feedwater polishing and is not designed for direct use with raw municipal or well water. It requires pretreatment to meet strict inlet specifications: maximum turbidity ≤0.2 NTU, free chlorine <0.1 mg/L, and total suspended solids (TSS) <1 mg/L. The module complies with ISO 9001:2015 manufacturing controls and conforms to electrical safety standards IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions). When integrated into a full ultra-pure water system, final output meets ASTM D1193 Type I, CLSI EP21-A, and ISO 15195:2018 requirements for clinical and analytical laboratory applications. For regulated environments, the module supports GLP/GMP-aligned validation protocols—including documented flow path materials (EPDM gaskets, PTFE seals), non-leaching construction, and compatibility with 21 CFR Part 11-compliant data logging systems when paired with external SCADA interfaces.
Software & Data Management
While the CYTTED150 operates as a standalone hardware module without embedded firmware or touchscreen interface, it is fully compatible with third-party supervisory control systems via standard analog signals (4–20 mA for resistivity, voltage, and current) and digital dry-contact alarms (e.g., low-flow, overvoltage, membrane fouling alert). Integration with PLC-based water management platforms enables automated logging of operational parameters in accordance with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Optional DIN-rail mount signal conditioners provide isolated analog inputs for centralized SCADA dashboards, facilitating trend analysis, preventive maintenance scheduling, and audit-ready electronic records compliant with FDA 21 CFR Part 11 when deployed with validated software infrastructure.
Applications
- HPLC, UHPLC, and LC-MS mobile phase preparation requiring low-conductivity, low-TOC water
- Cell culture media formulation and buffer preparation in biopharmaceutical R&D labs
- ICP-MS and GF-AAS trace metal analysis where chloride, sodium, and silica interference must be minimized
- Photolithography rinse processes in microelectronics research cleanrooms
- Calibration standard preparation for conductivity and pH reference solutions
- Supporting ISO/IEC 17025-accredited testing laboratories requiring documented water purity traceability
FAQ
What feedwater quality is required for optimal CYTTED150 performance?
RO permeate with conductivity ≤10 µS/cm, silica <0.5 mg/L, and SDI <3 is mandatory. Pre-filtration through 1 µm absolute and activated carbon polishing is strongly recommended.
Can the CYTTED150 be retrofitted into an existing ultra-pure water system?
Yes—provided hydraulic compatibility (pressure drop ≤1.2 bar at 150 L/h) and electrical supply (220 VAC ±10%, 50/60 Hz) are verified; engineering review of piping schematics and control signal mapping is advised prior to installation.
Does the module include built-in sanitization capability?
No—thermal or ozone-based sanitization must be performed upstream at the RO or storage loop level; the CYTTED150 stack is not rated for >40 °C continuous operation or oxidative chemical exposure.
What is the expected service life of the ion-exchange membranes and resins?
Under specified feedwater conditions and proper pretreatment, the stack typically achieves 3–5 years of continuous operation before performance decline necessitates replacement—validated via annual conductivity/resistivity trending and current efficiency monitoring.
Is technical support available for system validation and qualification?
Deepflow provides IQ/OQ templates, material certifications (3.1), and application engineering consultation; final PQ execution remains the responsibility of the end-user’s qualified validation team.
