Penguin Chillers 2 ½ HP Water Chiller

Before you buy

Penguin still lists the 2.5 HP, but on October 29, 2026 it was marked temporarily unavailable, with shoppers pointed to Penguin's scratch-and-dent section. Titanium and 316 stainless versions are both listed.

• Power: 208 to 240V, 14.7 A, 3,200 W, single phase. It will not run from a household outlet. The older listing below says 11 A and 2,410 W; plan for Penguin's current numbers.
• Cooling: 25,000 BTU/hr, rated 37 to 100°F with water.
• Size: 26.5 x 25 x 18.5 inches, 135 pounds. 61 dBA.
• Pump not included. Penguin recommends a Danner Mag Drive 5.0 to 18, or any pump rated under 10 PSI (23 feet of head).
• Indoor use only. Water must flow whenever the chiller is on. Unplug the chiller before you stop the pump.
• Warranty: 1 year included, with paid 2- and 3-year extensions.

Who it suits: big or heavily used tubs, small commercial setups, and rooms that get hot. It has more than three times the rated cooling of Penguin's plunge-specific Cold Therapy Chiller (7,500 BTU/hr), so a single home plunge rarely needs it. Our chiller sizing calculator will tell you.
