Veolia EDI Modules MK-3MiniHT For Hot Water Sanitizable
Product Overview
The MK-3MiniHT is Veolia's next-generation Hot Water Sanitizable (HWS) Electrodeionization (EDI) module, specifically designed for industries requiring ultra-pure water and strict hygiene standards. It supports 80°C hot water sanitization and is ideal for sterile environments in pharmaceuticals, biotechnology, microelectronics, and more.
Key Features
1. High-Temperature Sanitization
-
Temperature Tolerance: 80°C cyclic hot water sanitization (conventional EDI modules tolerate only 50°C), ensuring complete elimination of microorganisms (e.g., bacteria, endotoxins).
-
Sanitization Cycle: Supports daily or weekly automated sanitization without chemicals, avoiding secondary contamination.
2. Sanitary Design
-
Materials: 316L stainless steel end plates + high-inertness polymer flow paths, corrosion-resistant and non-leaching.
-
Seals: FDA-approved EPDM gaskets, heat-resistant and compliant with USP Class VI standards.
3. High-Efficiency Purification
-
Product Water Resistivity: Consistently ≥16 MΩ·cm (at 25°C), meeting USP/EP ultrapure water standards.
-
Low Energy Consumption: DC voltage ≤100V; integrated ion-exchange resin and membrane stack reduce energy use by 20%.
4. Compact Modular Structure
-
Flow Range: 0.5–2 m³/h (configurable), suitable for small-scale purification systems.
-
Connections: Sanitary Tri-Clamp quick-connect fittings for online installation/replacement.
