The Polar Monkeys Standard

Built different. On purpose.

The standard isn't good enough. Real ice. Serious cooling power. No compromises on the experience.

REAL ICE

Not just cold. Ice cold.

Others: Many chillers cool water without making ice.

HOT + COLD

32°F to 107°F. One system does it all.

Others: Often require separate systems for heating and cooling.

HIGH-POWER

Serious cooling chiller. Built for everyday use.

Others: Our 1.0 HP ChillX vs. many residential chillers at just 0.25–0.5 HP.

WHITE GLOVE

Premium delivery. Included.

Others: Curbside delivery or additional fees for in-home service.

2-YEAR

Warranty built to last. Backed to match.

Others: Many include just a 1-year warranty.

USA

American-assembled. Locally supported.

Others: Support may depend on overseas partners.

FROM ICE TO HEAT.

Craving an ice-cold reset or a warm recovery session? ChillX delivers both with precise temperature control and built-in ice-making technology. Set your temperature, and make every session yours.

  • 1.0 HP CHILLER
  • ICE-MAKING TECHNOLOGY

CLEANER WATER,
LESS WORK.

Spend more time in the water, not maintaining it. ChillX combines automatic filtration, continuous circulation, and built-in ozone technology to help keep your water cleaner between sessions.

  • AUTO FILTRATION
  • BUILT-IN OZONE

NO PLUMBING,
NO COMPLICATIONS.

Your recovery space, your way. Connect ChillX to your tub, fill it with water, and plug into a dedicated 110V outlet. No permanent plumbing or complex installation required.

  • PLUG & PLAY
  • NO PERMANENT PLUMBING

YOUR ROUTINE,
ON AUTOPILOT.

Your recovery shouldn't revolve around your schedule. Set your preferred session times, automate your ChillX operation, and manage your system from anywhere. Less adjusting. More time for what matters.

  • SMART SCHEDULING
  • REMOTE CONTROL

The tub changes.
The standard never does.

Three distinct systems. One non-negotiable level of quality. Whichever you choose, you're getting the best cold therapy system we know how to build.
