The Madimack InverCHLOR 300 is designed for efficient, low-maintenance pool sanitisation with intelligent control, real-time monitoring, and compatibility with both salt and mineral pool setups. Built for Australian conditions, it helps maintain clean, healthy water with less manual adjustment.
- Works with standard pool pumps
- Communicates directly with Madimack Inverflow pumps
- Can be used to run the pump and control Madimack InverEco Plus and Elite V4 heat pumps
- Does not communicate with Viron variable speed pumps
- Touchscreen LCD display with UV-protection cover
- Real-time alerts when salt or minerals need attention
- Suitable for low salt or mineral operation
Optional add-on: Pair it with the Madimack pH Doser for improved water balance and even clearer pool water.
Heat pump compatible: Synchronises with compatible Madimack heat pumps, allowing the heater to run outside standard filtration and chlorination times while still using the same circulation pump.
Variable speed pump integration: A direct-fit upgrade path for compatible Madimack Inverflow Plus pumps. Also suitable for many AstralPool and Hurlcon retrofit situations without plumbing changes, helping reduce running costs and noise.

Why Choose the Madimack InverCHLOR 300?
Long cell life: Intelligent control helps optimise operation and extend cell life beyond 10,000 hours.
Easy retrofit installation: Compact design that suits many existing pool systems and replaces many AstralPool and Hurlcon chlorinators without replumbing.
Low salt and mineral capability: Operates efficiently across ultra-low salt or mineral levels from 1,200 to 6,000ppm. Specifications are based on around 3,000ppm.
Smart monitoring: Real-time alerts help reduce guesswork and make routine pool care easier.
Built for outdoor use: Durable construction with a UV-protected front cover for long-term performance.
Modern controls: Touchscreen LCD interface for easy setup, adjustment, and day-to-day operation.
For a smart chlorinator upgrade with strong output, easy retrofit potential, and modern control, the Madimack InverCHLOR 300 is a strong option for medium to larger residential pools. Not recommended for standalon spas & swimspas.
In plumbing, named sizes are not the actual measurements. A pipe called “50mm” or “2"” does not measure 50 mm across. Instead, it follows nominal sizing, an internationally-standardised naming system.
Use the Outside Diameter (OD) to check your pipe against fittings. Below is a quick reference for common spa & pool pipe sizes:
| Imperial Name | Metric Name | Pipe Diameter (OD) |
|---|---|---|
| 1/2" | 15mm | ~21.2–21.5 mm |
| 3/4" | 20mm | ~26.6–26.9 mm |
| 1" | 25 mm | ~33.4–33.7 mm |
| 1.5" | 40 mm | ~48.1–48.4 mm |
| 2" | 50 mm | ~60.2–60.8 mm |
| 2.5" | 65 mm | ~75.2–75.5 mm |
These are nominal sizes and are designed to fit matching fittings — not to measure exactly what their name suggests. These are based on PVC Pressure Pipe AS/NZ 1477 Dimensions1.
- º Internal diameters vary slightly by manufacturer and class.
- 1 Not all pool/spa fittings match these dimensions exactly. Some do not follow Australian or international standards. Chinese spas may use proprietary fittings.
Understanding Plumbing Sizes & Nominal Measurements
Plumbing sizes can be confusing. PVC and many other pipe systems use nominal sizes—the size is a name, not the exact measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.
Why pipe sizes don’t match the measurements
The Nominal Pipe Size (NPS) system standardises pipe dimensions so that pipes, fittings, valves, and accessories interoperate. Plumbers work with these nominal names every day, but DIYers can be tripped up if they try to match by a tape-measure alone.
How to Measure Pipe Correctly
-
Pipe size is identified by:
- The pipe’s Outside Diameter (OD).
- The fitting’s Inside Diameter (ID) (socket opening).
- Pipe Class / Schedule (e.g., Class 9, 12, 18 or Sch 40) relates to wall thickness and therefore the Internal Diameter (ID) and pressure rating.
- The outside diameter of a fitting is not useful (wall thickness varies by manufacturer).
Hose & Tube Dimensions
Common flexible hose sizes used in pool/spa systems (approximate IDs).
| Imperial Name | Metric Name | Inside Diameter (ID) |
|---|---|---|
| 3/8" | 9–10 mm | ~9 mm |
| 3/4" | 19 mm | ~19 mm |
BSP – British Standard Pipe Thread Sizes
BSP thread names are also nominal. The thread OD will not equal the nominal name.
| BSP Thread Size Naming | Outside Diameter (mm / inch) | TPI |
|---|---|---|
| 1/16" BSP | 7.7 mm / 0.304" | 28 |
| 1/8" BSP | 9.7 mm / 0.383" | 28 |
| 1/4" BSP | 13.16 mm / 0.518" | 19 |
| 3/8" BSP | 16.66 mm / 0.656" | 19 |
| 1/2" BSP / 15 mm | 20.99 mm / 0.825" | 14 |
| 5/8" BSP | 22.99 mm / 0.902" | 14 |
| 3/4" BSP / 20 mm | 26.44 mm / 1.041" | 14 |
| 7/8" BSP | 30.20 mm / 1.189" | 14 |
| 1" BSP / 25 mm | 33.25 mm / 1.309" | 11 |
| 1-1/4" BSP | 41.91 mm / 1.650" | 11 |
| 1-1/2" BSP / 40 mm | 47.80 mm / 1.882" | 11 |
| 2" BSP / 50 mm | 59.61 mm / 2.347" | 11 |
| 2-1/4" BSP | 65.71 mm / 2.587" | 11 |
| 2-1/2" BSP | 75.18 mm / 2.960" | 11 |
| 3" BSP | 87.88 mm / 3.460" | 11 |
| 4" BSP | 113.03 mm / 4.450" | 11 |
| 5" BSP | 138.43 mm / 5.450" | 11 |
| 6" BSP | 163.83 mm / 6.450" | 11 |
