Know What You're Buying
Full specifications, what's in the box, and everything you need to plan your install.
7,500 BTU/hr of cooling with the pump already built in — add it to a tub you already own and stop buying ice.
Penguin Chillers has been building water chilling equipment in Knoxville, Tennessee since long before cold plunging went mainstream. This is the unit that does the work behind most of their cold therapy setups: a titanium coil exchanger, quick connect camlock fittings, and enough capacity to pull a standard plunge down to 37°F and hold it there for around $18 a month in electricity.
Pick the Install & Filter Kit option if you are starting from a bare tub — it adds the bulkheads, tubing, fittings and washable filter you need to plumb it in.
Warranty
1 year limited manufacturer warranty is included as standard. A 2 or 3 year extension can be added above. Claims are handled directly by Penguin Chillers: (865) 214-6509 or support@penguinchillers.com.
Not covered: normal wear and tear, damage caused by freezing, improper installation, running the unit without a filter or with a filter finer than 50 microns, use with an ozone venturi, and any failure to follow the manufacturer's installation, use or care instructions.

Before you order — installation limits
- The pump is not self-priming. The chiller has to sit level with or below the bottom of your tub so it gravity primes — never elevate it above the tub.
- Place it within about 3 ft of the tub drain wherever possible.
- The bulkheads in the Install & Filter Kit only fit tubs with a wall thickness of 1/4 inch or less. Measure before you order.
- Never run a filter rated below 50 microns, and do not use with an ozone venturi.
- Needs a standard 110–120V outlet. Rated for outdoor use above 32°F — below freezing, disconnect and drain completely.
