Active Aqua Water Chiller All in One - 1/3 HP

Yes! The Active Aqua 1/3 HP All in One is the outdoor workhorse of the lineup, built for cold plunge duty with the circulation pump, 20 micron filtration, and ozone sanitation already built in. Unlike the indoor Active Aqua units, there is nothing extra to buy: connect the plumbing to your tub, plug in the GFCI protected cord, and plunge. Plunge Crafters is an authorized Active Aqua dealer, so every unit ships new with the full manufacturer warranty.

It cools water down to 39°F, with a digital set point range of 39°F to 82°F. That covers the full cold therapy range, from deep cold at 39°F to milder recovery temperatures, with no ice required. Once your water reaches the set point, the chiller cycles on and off automatically to hold it. Your tub size, insulation, ambient temp and sun exposure still affect how fast it pulls down and how hard it works to hold temperature.

With its built-in 800 GPH circulation pump, it is sized for typical backyard cold plunge builds, including standard stock tanks. Not sure it is the right match for your tub? Contact us with your tub's gallon capacity and we will confirm fit before you order. Building indoors instead? The Active Aqua 1/4 HP covers tubs from 40 to 92 gallons and the Active Aqua 1/2 HP covers 90 to 172 gallons.

Yes, that is exactly what it is built for. It has a rainproof design, corrosion-resistant ABS housing, and a GFCI protected power cord, and it is approved for outdoor use. It is the model to choose for backyard, patio, and poolside cold plunge setups, and it works just as well in a garage or gym if you ever move it indoors. Shop all cold plunge chillers.

Yes, the pump is built in. An integrated 800 GPH circulation pump moves water between your tub and the chiller, so there is no separate pump to buy, size, or plumb. That is one of the biggest differences from the indoor Active Aqua units, which require an external pump sold separately.

Boost runs the chiller at maximum output to accelerate cooling, useful right after you fill the tub or do a water change. Once your water reaches the set point, the chiller cycles on and off automatically in normal mode to hold your temperature, so you only run Boost when you need the fast pull-down.

Yes. It has built-in 20 micron filtration with a washable, reusable cartridge, plus a built-in ozone generation system that helps keep water clean and clear between changes. Rinse the filter cartridge regularly and you will go longer between water changes with less chemical maintenance. The indoor Active Aqua units do not include filtration, which makes this the pick if you want sanitation handled in one box.

It runs on standard 120V household power, drawing 5.0 amps during operation, and the GFCI protection is built into the power cord itself, which is exactly what you want for outdoor wet-area equipment. No special wiring or dedicated circuit is required for most homes. Never run it on an undersized extension cord.

It ships with 1/2", 3/4", and 1" fittings plus two water adaptors, so it connects to the plumbing used in most DIY cold plunge builds. Need adapters, hose, or bulkheads to finish the connection to your tub? Browse our fittings, hose and bulkheads collection or contact us and we will spec the connections for your build.

Install it on a stable, level surface positioned below your tub's water level, with clearance on all sides so it can pull in air and dissipate heat. The locking caster wheels make it easy to roll into position and keep it planted once it is there. Keep it out of direct sunlight where possible: shade helps any chiller work less to hold temperature.

Not through freezing weather. Drain and disconnect the unit when temperatures drop below freezing to protect the pump, plumbing, and heat exchanger. Water expands as it freezes and can crack internal components. If you plunge year-round in a cold climate, move the system to a garage or covered space for the winter months.
