Hot Water Electrodeionization System
Gujarat Ion Exchange and Chemicals Ltd is a leading manufacturer and supplier of Hot Water Sanitizable EDI Systems in India. hot water sanitizable Electrodeionization (EDI) systems, engineered for industries demanding ultrapure water and stringent microbial control—such as pharmaceuticals, biotechnology, food & beverage, and laboratories.
These systems integrate continuous electrodeionization with robust, thermally stable construction, allowing for periodic hot water sanitization (up to 85°C) without the need for chemical agents. This ensures both high-purity water production and effective microbial management.
Key Advantages Hot Water EDI System
- Chemical-Free Operation: Eliminates the need for acid and caustic regeneration.
- Consistent Ultra-Pure Water: Delivers >16 MΩ-cm resistivity water continuously.
- Low Maintenance: No downtime required for regeneration; minimal moving parts.
- Compact & Modular Design: Easy to integrate with RO and polishing systems.
- Sanitary Construction: Made from FDA-compliant and hygienic materials for cleanroom environments.
- Fully Automated: Advanced PLC control with real-time conductivity, temperature, and pressure monitoring.
- Regulatory Compliance: Meets pharmaceutical water standards including USP, EP, and WFI (when part of validated system).
