40g/h Self-Cleaning Salt Chlorinator Unit
Built for large residential pools and demanding climates. The Century 40g/h model offers maximum chlorine output with minimal maintenance.
- Produces a massive 40 grams of chlorine per hour
- Rated for large inground pools up to 40,000 gallons.
- Advanced automatic reverse polarity cycle.
Heavy-Duty Electronic Chlorine Generator (ECG)
When dealing with large water volumes or extreme summer heat, undersized equipment fails. The Century 40g/h electronic chlorine generator (ECG) is engineered specifically to handle heavy usage without burning out the control board. Many of our contractor partners consistently rate this model as the best salt chlorinator for inground pools due to its oversized titanium plates. Furthermore, it operates as a fully automated self-cleaning salt chlorinator, frequently reversing its electrical polarity to shed calcium scale. If you are looking for a reliable, high-margin chlorinator unit to add to your wholesale catalog, this 40g/h model delivers unmatched ROI.
40g/h Pool Chlorine Generator: Standard Technical Specifications
Automated Reverse Polarity: Hard water destroys standard cells. The Century 40g/h power supply is programmed with an automatic reverse polarity function. By shifting the electrical charge on a set cycle, the system actively repels and sheds calcium buildup from the electrolytic plates, drastically reducing the need for field technicians to perform manual acid washes.
Full-Amp Load Endurance Testing: High-capacity systems must run hard during the peak of summer. We subject this model to long-term, full-power endurance tests on the factory floor. We verify that the internal heat sinks and rectifiers can sustain 100% output continuously without thermal degradation, ensuring it handles oversized pools without failing.

40g/h Pool Chlorine Generator: Applications
Built for Demanding Climates & Hard Water
Designed for regions that push pool equipment to its limits through intense heat, high bather loads, or aggressive water chemistry.
- Sun Belt Region Pools (AZ, TX, FL): Essential for Southern states where high UV index and warm water rapidly deplete free chlorine residuals.
- Hard Water Districts: The go-to solution for municipal water zones with high calcium hardness, where the self-cleaning feature is mandatory to prevent rapid scaling.
- Oversized Freeform Pools: Perfect for large, custom residential pools (up to 40,000 gallons) that require heavy-duty daily chlorine production.
Frequently Asked Questions (FAQs)
The 40g/h electronic chlorine generator (ECG) utilizes an automatic reverse polarity cycle. It periodically reverses the electrical current to shed calcium scale from the titanium plates, drastically reducing manual acid washing.
The control board is programmed with adjustable reverse polarity intervals, allowing technicians to set it based on local water hardness levels.
The control board is programmed with adjustable reverse polarity intervals, allowing service technicians to set it (e.g., 2, 4, or 8 hours) based on local calcium hardness levels.
"Sizing up" is a common professional practice. A 40g/h unit running at 50% capacity will last nearly twice as long as a 20g/h unit running at 100%, offering a much better return on investment.
While it drastically reduces the frequency, in very hard water areas, a quick visual inspection every 6 months is still recommended, and a mild acid wash may be required occasionally.
By utilizing thicker MMO coatings and the self-cleaning feature, the Grade 1 titanium plates are designed to deliver over 10,000 hours of active electrolysis under proper water chemistry conditions.
Yes, producing 2.12 lbs of chlorine per day, this electronic chlorine generator (ECG) is specifically engineered to handle intense direct sunlight and heavy bather loads without depleting free chlorine levels.
