At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

Astral Sel 9-Plate: High-Durability Electrolysis Engineering

The Astral Sel 9-plate electrode is the original disinfection component for AstralPool salt chlorination systems. This device uses titanium plates coated with noble metals to transform sodium chloride into a high-purity active disinfectant. The cost of inaction when using compatible electrodes results in poor disinfection and a risk of short circuits in the control equipment. The Astral Sel Cell ensures stable chlorine production, protecting the health of users and the technical integrity of the installation.

Disinfection Efficiency via Reinforced Titanium Plates

The Astral Sel 9-plate cell is designed to maximize electrical contact surface within the water flow. This engineering configuration allows for efficient hydrolysis even under conditions of high chemical demand.

  • Long-Lasting Coating: The plates feature a special treatment that extends effective operating hours in aggressive saline environments.

  • Homogeneous Production: The 9-plate design ensures a constant release of free chlorine, avoiding oxidation spikes that damage the pool liner.

  • Operational Sustainability: Optimizes the salt chlorinator's electrical consumption by requiring less intensity to generate the necessary oxidation potential.

  • Precision Installation: The connection terminal is designed for a perfect fit, preventing terminal overheating caused by loose contacts.

Mechanical Robustness and Safety Standards

The construction of the Astral Sel Electrode follows AstralPool's industrial quality standards. Its architecture facilitates rapid replacement in the technical room, reducing downtime in residential and commercial facilities.

  • Chemically Resistant Body: The support materials are prepared to withstand the injection of pH correctors and high temperatures in the return flow.

  • Protected Terminals: Electrical connection points feature protection to prevent corrosion from ambient humidity inside the cell.

  • Polarity Reversal Architecture: Designed specifically to work with the self-cleaning cycles of Astral Sel equipment, minimizing scale buildup.

  • Factory Certification: Each electrode undergoes conductivity tests to ensure it meets the specified grams of production per hour.

  • Available in 4 models:

    • For Sel Astral 40: 28419 (former ref. 4408060124)
    • For Astral Sel 60 / Sel Pure 60: 54054 (former ref. 4408060125)
    • For Astral Sel 100 / Sel Pure 100: 54055 (former ref. 4408060126)
    • For Astral Sel 160 / Sel Pure 160: 54056 (former ref. 4408060127)

Technical Specifications

  • Number of Plates: 9 titanium plates.

  • Brand: AstralPool (Original).

  • Compatibility: Fluidra Astral Sel and Sel Pure systems.

  • Coating Material: Precious metal mix (Ruthenium/Iridium).

  • Cleaning Type: Compatible with electronic polarity reversal.

  • Estimated Lifespan: Between 3000 and 5000 hours (depending on water hardness).

  • Electrical Connection: Threaded or pressure terminals (depending on manufacturing version).

Compatibility and Application Limits

The Astral Sel 9-plate electrode is exclusively compatible with salt chlorinators in the Astral Sel and Sel Pure range that use this plate configuration. It must be installed after the filter and before any heating system.

TECHNICAL RESTRICTION: Do not submerge in high-concentration acidic solutions (greater than 10%) for prolonged periods, as this degrades the plate coating. Do not operate with salinity below 3000 ppm to avoid premature titanium wear.

Frequently Asked Questions

  • Why choose the original AstralPool electrode instead of a compatible one? The original Astral Sel Electrode ensures that the chlorinator correctly detects water conductivity. Compatible models often trigger "low salt" errors and have up to 50% shorter lifespans due to their low precious metal content.

  • When should I replace my Astral Sel 9-plate cell? You should perform the replacement when you observe that chlorine production is null despite having the correct salt levels (approx. 4000 ppm). If the plates are white or worn out after cleaning, their chemical reaction capacity has been exhausted.

  • How can I extend the life of this replacement part? Keep the water pH between 7.2 and 7.4. Uncontrolled pH forces the cell to work more hours than necessary, accelerating the wear of the Astral Sel titanium plate coating.
