Continuous Electrodeionization CEDI Water System for Pharma Boiler Applications
The continuous electrodeionization cedi water system pharma boiler is engineered to deliver ultra‑pure, de‑ionized water directly into pharmaceutical steam‑generation lines. Designed for 24/7 operation, this modular CEDI unit eliminates the need for chemical regeneration, ensuring consistent conductivity below 0.1 µS/cm while protecting boiler tubes from scaling and corrosion. Ideal for GMP‑compliant facilities, the system integrates seamlessly with existing boiler feedwater loops, offering a compact footprint and low total cost of ownership.
By coupling ion‑exchange membranes with a low‑voltage electric field, the solution continuously removes residual ions, producing water that meets USP <659> and EP standards without interrupting boiler uptime.
How It Works – Continuous Electrodeionization in a Nutshell
The system contains alternating cation‑exchange (CEM) and anion‑exchange (AEM) membranes arranged in a stack. Feedwater flows through the ion‑exchange resin beds, where the majority of ionic contaminants are captured. A DC voltage (typically 5‑12 V) is applied across the membrane stack, creating an electric field that drives the bound ions through the membranes into a separate concentrate stream, which is safely discharged.
Because the electric field continuously sweeps ions away, the resin never reaches exhaustion, eliminating the costly chemical regeneration cycles required by conventional de‑ionizers. The result is a steady, high‑purity water supply that matches the demanding specifications of pharmaceutical steam generation.

- Retrofit projects for existing boiler plants seeking to upgrade from batch ion‑exchange to a nonstop CEDI solution.
Competitive Advantages
• Zero‑chemical regeneration – eliminates hazardous waste handling and reduces operating expenses.
• 24/7 reliability – designed for continuous duty cycles with built‑in redundancy and easy module replacement.
• Compact modular design – footprint up to 40 % smaller than traditional mixed‑bed de‑ionizers, freeing up valuable plant space.
• Regulatory alignment – meets USP <659>, EP, and cGMP water‑purity standards without additional validation steps.
• Scalable capacity – multiple modules can be paralleled to match future expansion of boiler demand.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑size system?
MOQ starts at a single 500 m³/h module, which can be configured with optional pre‑treatment stages. Larger capacities are built by stacking additional modules.
Can the system be tailored to specific boiler pressure ranges?
Yes. All wetted parts are fabricated from 316L stainless steel and can be pressure‑rated up to 25 bar (≈ 360 psi). Custom pressure ratings are available on request.
What is the typical lead time after order confirmation?
Standard lead time ranges from 15 to 45 days, depending on module count and any additional instrumentation required.
What warranty and support options are offered?
A standard 24‑month parts‑and‑labor warranty is provided. Extended warranty and on‑site service contracts can be added to match the plant’s maintenance strategy.
