Scale Wear Design CHILLA pool aerator chiller for 1.5" returns — lowers water 6–10°F, no electricity

CHILLA is a simple, no-electricity pool aeration fountain that lowers pool water temperature by 6–10°F using your existing return line.

Built to thread into a standard 1.5" in-ground pool return, the Scale Wear Design CHILLA uses aeration and evaporative cooling to drop water temperatures over a few days without adding electrical load or expensive equipment. It installs in minutes, is removable, and can be combined with a second unit for larger pools or faster cooling. This approach offers a budget-friendly alternative to powered chillers while also providing an attractive fountain effect children enjoy and adults appreciate at night.

How does CHILLA lower my pool temperature without electricity?

CHILLA redirects water through a fountain-style aerator so surface water sprays and mixes with drier air, increasing evaporation and releasing heat. Over 48–72 hours of regular circulation you’ll see measurable cooling, especially when run overnight or during lower-humidity periods.

• Operates using your pool pump and 1.5" return line — no extra power draw.
• Aeration increases evaporation, which removes heat from the pool water.
• Most effective when run continuously or during cooler night hours.

Will CHILLA fit my pool and how do I install it?

The chiller is designed for standard 1.5" threaded in-ground pool returns; measure your return to confirm compatibility before ordering. Installation requires unscrewing the existing 1.5" cap, attaching the supplied 1.5" adapter, and pressing the fountain into place — no gluing or permanent modifications needed.

• Fits 1.5" female threaded returns commonly found on in-ground pools.
• No glue: screw in adapter, press in fountain, and it's ready to run.
• Close unused return ports with 1.5" plugs to maximize flow through the CHILLA.

How much cooling can I expect and how long will it take?

Expect a temperature drop in the range of about 6–10°F when correctly sized for your pool; results depend on pool volume, sun exposure, humidity, and pump runtime. Typically the effect becomes noticeable within 2–3 days; installing a second unit helps larger pools reach lower temperatures faster.

• Typical cooling: 6–10°F under favorable conditions.
• Visible change often in 48–72 hours of consistent use.
• Install two units for larger pools or quicker temperature reduction.

Is CHILLA safe, and will it affect my pool system?

CHILLA is non-powered and designed to work with standard pool returns, minimizing risk to equipment. It sits in the return line and should not require plumbing changes, but always follow the included installation video and ensure secure fittings to prevent leaks or flow restriction.

• Non-electric design avoids additional power draw or wiring.
• Removable and non-permanent — no chemical or structural changes.
• Follow instructions and watch the installation video for correct setup.

Who is this for? CHILLA is ideal for pool owners seeking an affordable, low-maintenance way to cool in-ground pools without buying a powered chiller. It's a good choice for families who want a playful fountain feature for kids, owners who want quieter night-time water sounds, and anyone looking to shave several degrees off pool temperature while keeping operating costs minimal. Measure your return fitting, consider your pool size, and add a second unit if you have a large volume or want faster results.
