Hot Water E-Cell Stack MK-3PharmHT

Summary

Product identification

The E-Cell* EDI MK-3PharmHT Stack is a hot water sanitizable electrodeionization (EDI) stack designed to provide ultrapure water for the pharmaceutical and biotechnology industries.

Key features include:

• Uses electrical current for ultrapure water production.
• Hot water sanitizable up to 185ºF (85ºC) for 160 cycles.
• Delivers high product water quality and low energy consumption.
• Minimizes cleaning requirements at higher feed water hardness levels using counter-current operation.
• Leak free, with a standard 3-year prorated warranty.
• Operates continuously, requiring no caustic or acid for regeneration of ion exchange resin.
• Requires no brine injection or concentrate recirculation.

Typical Applications: The product water from this stack can exceed USP, EP, and other pharmacopeia required quality levels in applications such as:

• Water for injection
• Pharmaceutical purified water
• Laboratory purified water systems

Quality Assurance:

• CE, RoHS, CSA and EAC marked
• Materials in contact with fluids meet FDA requirements
• Certified with UKCA
• Manufactured in an ISO 9001 and ISO 14001 facility
• Halal certified by the Islamic Food and Nutrition Council of America (IFANCA®)

Mechanical / Hydraulic

• Nominal Flow: 3.4 m3/h (15 gpm)
• Flow Rate Range: 1.6–5.4 m3/h (7.0–23.8 gpm)
• Shipping Weight: 100 kg (220 lbs)
• Dimensions (width x height x depth): 30 cm x 61 cm x 54 cm (12’’ x 24” x 22”)

Operating limits

• Recovery: Up to 96%
• Inlet Pressure: ≤ 6.9 bar (100 psi) (Determined by downstream pressure requirements, operation choice, and stack pressure drop.)
• Pressure Drop: 1.4–2.8 bar (20–40 psi) (At nominal flow and 25°C.)
• Hot Water Sanitization Cycles: 160
• Maximum Sanitization Temperature: 85ºC (185ºF)
• Maximum Sanitization Inlet Pressure: 2.1 bar (30 psi)

Product water

Guarantees available based on site conditions and design:

• Resistivity: ≥ 10 MOhm-cm
• Sodium: ≥ 99.9% removal
• Silica (SiO₂): Up to 99% removal

Electrical

• Voltage: 0–300 VDC
• Amperage: 0–5.2 ADC

Feed water

• Total Exchangeable Anions (TEA as CaCO₃): ≤ 63.6 ppm (At minimum flow and maximum temperature, represents all anions including OH⁻, CO₂, and SiO₂.)
• Conductivity Equivalent: ≤ 109 μS/cm
• Temperature: 4.4–40˚C (40–104˚F)
• Total Hardness (as CaCO₃): ≤ 1.0 ppm (Applies to standard counter-current flow. Decreases to 0.1 ppm in co-current flow.)
• Silica (SiO₂): ≤ 1.0 ppm (Allowable limit decreases above nominal flow and to 0.5 ppm with feed water hardness above 0.5 ppm as CaCO₃.)
• Total Organic Carbon (TOC as C): ≤ 0.5 ppm
• Total Chlorine: ≤ 0.05 ppm
• Fe, Mn, H₂S: ≤ 0.01 ppm
• Boron: ≤ 1.0 ppm (Limited to 0.3 ppm as B if a silica guarantee or resistivity guarantee above 10 MOhm-cm is required.)
• pH: 4 to 11
• Oil & Grease: None detectable
• Particulate: RO permeate (RO or equivalent feed water is required as EDI stacks contain packed beds of ion exchange medium that cannot be backwashed. Systems with an open system between RO and E-Cell must be fitted with filters, typically 5 µm absolute or 1 µm nominal, immediately preceding the E-Cell.)
• Oxidizing Agents: None detectable
• Color: ≤ 5 APHA (Defined by ASTM D1209.)
