Penguin Chillers Barrel Cold Therapy Package

This package pairs Penguin's Cold Therapy Chiller — 7,500 BTU/hr of cooling, a built-in pump, a 150-micron washable and reusable filter, R-32 refrigerant, and a 56 dBA sound rating in an outdoor-rated 17 x 15 x 13-inch, 49-lb unit — with the brackets, hoses, and quick-connect fittings to plumb it into a compatible Ice Barrel (buyers choose the 300/500 kit or the 400 kit). It chills water down to 37°F and, per Penguin, easily holds normal plunge temperatures in the low-to-mid 40s°F, running on a standard 110-120V circuit at 450W/3.9A with an estimated operating cost as low as $18/month at $0.12/kWh. It is plug-and-play with no tools required, ships free in the continental 48, and is built in Knoxville, Tennessee.

The fine print matters. Penguin states plainly that it does not sell the Ice Barrel — this listing is hardware to cool a barrel you already own or buy separately, so the real all-in cost of a chilled setup includes the tub. The pump is not self-priming: the chiller must sit at or below the tub's drain level, ideally within 3 feet, and it should not be paired with sub-50-micron filters or ozone venturis. Standard warranty is 1 year, extendable to 2 years (+$189.99) or 3 years (+$289.99), which trails the multi-year coverage on some all-in-one plunges. Penguin publishes no horsepower figure for this unit, only the BTU rating. For owners of passive barrels tired of ice runs, though, this is a directly sourced, US-made route to set-and-forget cold water.
