Cold water without the ice run

The Penguin is for an existing tub that needs repeatable cold water without bags of ice taking over the weekly routine. Its 3/4 HP system provides 7,500 BTU/h of cooling, and the pump and filter are built into the same 49 lb unit.

Give the pump an easy job

Gravity-prime the system before startup. Place the chiller within 3 feet of the tub drain, with the bottom of the chiller at or below the bottom of the tub. Short, simple plumbing helps the pump stay primed.

What to expect

Under favorable conditions, the Penguin can hold water in the low 40s or high 30s. Tub volume, insulation, shade, outdoor temperature, and plumbing all matter. The honest number is the temperature your whole setup can hold, not the lowest number printed on a chiller page.

  • 110 to 120V, 450W, 3.9A.
  • 56 dBA operating noise.
  • 17 in wide x 15 in deep x 13 in high.
  • 49 lb with a 10 ft GFCI-protected power cord.
  • Rainproof housing for indoor or outdoor use.
  • Made in the USA with a one-year product warranty.

Disconnect the chiller during freezing conditions. Filtration cuts down on water changes, but the tub still needs normal cleaning and water care.

Call or text (844) 565-1113 with the tub volume, drain location, climate, and whether it will live indoors or out. We will help you check the layout before you cut hose.

Manuals and controller guides

Penguin publishes separate guides for current and discontinued Cold Therapy Chiller designs. Use the guide that matches your unit’s label, controller, and hose connections. Find the chiller and controller guides in Penguin’s manufacturer manual library.

“The Ben(s) have been absolutely amazing to work with. From emails, to phone calls, to (late) night texts, they have literally answered every question with care, complete accuracy and honesty. And, sometimes a bit of humor. Seriously, couldn't recommend them and the entire SaunaMarketplace team highly enough if you are in the market for a sauna, a heater or any type of related item.”
