8. Frequently Asked Questions (FAQ)

Q1: Which ABB medium-voltage drives is this deionizer compatible with? Can my drive use it? A: The SW-190148 (3BHB043813R0001 / Q-0621-A) deionizer is mainly compatible with ABB ACS1000, ACS6000, PCS6000 and other medium-voltage drive series using water cooling systems, matching Q-0621-A deionizer housing. Whether your drive can use it requires confirmation:

1. Complete model and series of your drive (e.g., ACS1000, ACS6000, PCS6000, etc.)
2. Whether the drive uses water cooling system (some medium-voltage drives use air cooling, no deionizer needed)
3. Whether the deionizer housing model in the water cooling system is Q-0621-A
4. Whether the original deionizer model is SW-190148 or compatible model It is recommended that you provide the complete model of the drive and water cooling system configuration (or photo of original deionizer label), and we can assist in confirming compatibility. If your drive is not applicable to this model, we can also recommend the corresponding model deionizer.

Q2: How often does the deionizer need to be replaced? How to judge it's time to replace? A: According to ABB medium-voltage drive preventive maintenance guidelines, the average service life of the deionizer is 2-4 years, but specific life depends on the following factors:

• Inlet water quality: Higher ion content in makeup water, faster resin saturation, shorter life
• System operating temperature: Higher water temperature, faster ion exchange reaction, relatively shorter resin life
• Cooling water circulation volume: Larger system water volume and more frequent circulation, greater ion load
• System sealing: System air leakage and contaminant ingress will accelerate resin failure

Basis for judging replacement:

1. Conductivity continuously rises: This is the most important criterion. When cooling water conductivity continuously rises, exceeds the set threshold (typically 1-2 μS/cm, specific subject to drive setting), and does not decrease after venting, water replenishment and other operations, it indicates ion exchange resin is approaching saturation
2. Reached recommended replacement cycle: Even if conductivity has not exceeded standard, replacement is recommended after 4 years of use to avoid sudden resin failure
3. Drive alarm: Some drives have high conductivity alarm, when this alarm occurs, deionizer should be inspected and replaced

It is recommended to test conductivity once a month and record, establish trend curve, 便于提前 predict replacement time.

Q3: Why simultaneously replace fine filter and clean strainer when replacing deionizer? A: This is a clear recommendation in ABB official preventive maintenance guidelines, for the following reasons:

1. System overall cleanliness guarantee: Deionizer, fine filter and strainer together constitute the purification circuit of the water cooling system. Deionizer is responsible for removing dissolved ions, fine filter is responsible for removing suspended particles (such as corrosion products, resin debris, dust, etc.), strainer is responsible for intercepting larger impurities. Only replacing deionizer without replacing fine filter, contaminants accumulated in old filter may continue to enter system, affecting deionization effect and water quality.
2. Avoid new cartridge contamination: Old fine filter may have accumulated particulate impurities and microorganisms, after replacing new deionizer, if continuing to use old filter, contaminants may enter new deionizer with water flow, block resin pores, reduce ion exchange efficiency, shorten new cartridge service life.
3. Maximize maintenance efficiency: When replacing deionizer, shutdown, drainage, disassembly of water cooling system components are already required, simultaneously replacing fine filter and cleaning strainer can be completed in the same shutdown maintenance, avoiding secondary shutdown maintenance in short term, improving maintenance efficiency, reducing total downtime.
4. ABB official maintenance specification: This is standard operating procedure in ABB medium-voltage drive maintenance manual, following this recommendation can ensure long-term stable operation of water cooling system, maintain drive original factory warranty conditions.

Therefore, we recommend purchasing corresponding fine filter cartridge simultaneously when purchasing deionizer, ensuring maintenance work is complete and thorough.

Q4: What type of resin is in the deionizer? Can I replace the resin myself? A: The SW-190148 deionizer contains mixed-bed ion exchange resin, i.e., cation exchange resin and anion exchange resin mixed and filled in a certain proportion. Among them:

• Cation exchange resin: Removes cations such as calcium (Ca²⁺), magnesium (Mg²⁺), sodium (Na⁺) from water
• Anion exchange resin: Removes anions such as chloride (Cl⁻), sulfate (SO₄²⁻), bicarbonate (HCO₃⁻) from water After the two resins are mixed, cations and anions are simultaneously removed when water flows through, achieving deep deionization, effluent conductivity as low as below 0.1 μS/cm.

Regarding self-replacement of resin:

• The SW-190148 is an integral drop-in cartridge, designed for overall replacement, users are not recommended to open the tank and replace resin by themselves
• Self-replacement of resin has the following risks:
  1. Tank sealing structure may be damaged, leading to water leakage
  2. Resin type, mixing ratio, filling amount are difficult to accurately match original factory specifications, affecting deionization effect
  3. Resin may be contaminated during replacement, introducing impurities
  4. May lose ABB original factory warranty
  5. Regeneration and disposal of old resin require professional equipment and environmental protection qualifications
• Correct approach: Overall replace with new SW-190148 deionizer, old cartridge disposed of per industrial waste regulations. If you have a large number of old cartridges to dispose of, it is recommended to contact a professional hazardous waste treatment company.

Q6: How long after replacing deionizer does conductivity drop? What if it doesn't drop?

A: After replacing new deionizer, the drop speed of cooling water conductivity depends on system water volume, circulation flow and initial conductivity:

Normal downward trend:

• Run circulation immediately after replacement, conductivity should start to gradually decrease
• Small system (< 100L): Usually can drop to normal range (< 1 μS/cm) within 1-4 hours
• Medium system (100-500L): Usually can drop to normal range within 4-24 hours
• Large system (> 500L): May take 24-72 hours to fully drop to normal range
• Higher initial conductivity, longer time required to drop

If conductivity doesn't drop, troubleshoot in following steps:

1. Confirm deionizer installed correctly: Check cartridge orientation, sealing ring in place, inlet/outlet valves fully open
2. Check system venting: Residual air in system will affect water circulation and deionization effect, thoroughly vent
3. Check circulation flow: Confirm circulation pump running normally, flow reaches rated value, too low flow will lead to insufficient deionization
4. Test makeup water quality: If makeup water itself has high conductivity (such as tap water), will continuously introduce ions, should use deionized water or pure water for replenishment
5. Check system for leaks or air ingress: System air leakage will cause carbon dioxide dissolution, raising conductivity; leaks will lead to frequent replenishment of high-conductivity water
6. Check for external contamination sources: Such as heat exchanger leakage (process medium mixed into cooling water), pipeline corrosion products, etc.
7. Confirm new deionizer is normal: Check tank for damage, whether resin is normal (can contact supplier for confirmation)
8. Contact technical support: If still cannot resolve after above troubleshooting, recommended to contact ABB technical support or our technical team for assistance in diagnosis

Q7: What are the storage conditions and shelf life of the deionizer?

A: The SW-190148 deionizer contains wet ion exchange resin, pay attention to the following conditions during storage:

Storage conditions:

• Temperature: Recommended to store in 5-30°C environment, avoid high temperature (> 40°C) and freezing (< 0°C). High temperature will accelerate resin degradation, freezing will cause resin ice expansion and rupture
• Humidity: Store in dry, ventilated indoor environment, avoid moisture causing tank external rust or label damage
• Light protection: Avoid direct sunlight, ultraviolet rays may accelerate resin and tank material aging
• Sealing: Keep original factory packaging sealed, prevent resin moisture evaporation and drying. Resin once dried will fail and cannot be recovered
• Upright storage: Recommended to store upright, avoid horizontal or inverted placement causing uneven resin distribution
• Away from contaminants: Away from chemicals, organic solvents, strong electromagnetic radiation and other substances that may contaminate or damage the product

Shelf life:

• Unopened original factory packaging: Under correct storage conditions, shelf life is typically 2-3 years (from production date). Specific subject to product label or ABB official instructions
• Opened but unused: After opening, if not installed and used, should be sealed and stored as soon as possible, recommended to use within 6 months
• Installed and in use: Service life 2-4 years (depending on water quality and operating conditions), with conductivity as replacement criterion

Notes:

• Deionizer exceeding shelf life is not recommended for use, resin may have partially degraded, affecting deionization effect
• Regularly check packaging integrity and leaks during storage
• Recommended to follow "first in first out" principle, prioritize using products with longer storage time
• For long-term storage (> 1 year), recommended to check storage status and product integrity once a year
