FrostCore F85 1 HP Cold Plunge Water Chiller with Wi-Fi & Ozone

Transform a compatible tub into a streamlined cold-plunge system with the FrostCore F85 1 HP Cold Plunge Water Chiller. Engineered for powerful cooling, convenient water management, and easy everyday operation, the FrostCore F85 delivers controlled water temperatures without the ongoing need for bags of ice.

With a 9,553 BTU/h maximum cooling capacity, built-in circulation pump, filtration system, ozone sanitation, and smart Wi-Fi controls, the F85 brings the essential components of a cold-plunge setup together in one compact system.

Designed for water volumes of approximately 80–132 gallons, it can be paired with dedicated plunge tubs as well as many standard, soaking, and inflatable tubs.

Powerful 1 HP Cooling Performance

At the heart of the FrostCore F85 is a powerful cooling system designed to maintain cold-plunge temperatures with greater consistency and convenience than manually adding ice.

The system offers an adjustable water-temperature setting range of 36°F–86°F, allowing you to customize your plunge to your preferred temperature.

A rotary compressor and titanium heat exchanger support efficient cooling, while the integrated circulation pump keeps water continuously moving through the system.

Integrated 3-Stage Water Management

The FrostCore F85 goes beyond temperature control with an integrated water-management system designed to help keep plunge water cleaner between changes.

The system combines:

• 40-micron pre-filter to capture hair and larger debris
• 20-micron filter for finer sediment
• Ozone sanitation to support ongoing water treatment

Together with continuous water circulation, these features create a more convenient cold-plunge experience with less reliance on manual water maintenance.

Smart Wi-Fi Control

Manage your plunge from the integrated touchscreen or connect the FrostCore F85 to a compatible smartphone over 2.4 GHz Wi-Fi.

Smart controls allow you to adjust settings, create operating schedules, activate disinfection functions, lock or unlock controls, and monitor system status remotely.

Schedule the system ahead of your routine so your plunge can be prepared when you are.

Compatible with Multiple Tub Styles

A dedicated cold-plunge tub isn't required. The FrostCore F85 is designed for use with compatible:

• Cold-plunge tubs
• Standard bathtubs
• Soaking tubs
• Inflatable plunge tubs

For dedicated plunge tubs, the inlet and outlet lines can be connected to compatible ports. For suitable open tubs, the hoses can be positioned directly below the waterline according to the manufacturer's installation instructions.

Built for Convenient Setup

Insulated inlet and outlet hoses help reduce unwanted temperature loss and condensation, while camlock-style connections simplify installation.

The unit also incorporates practical protection features including a GFCI plug, freeze protection, flow monitoring, and system alarms.

Its IPX4-rated housing provides protection against water splashes, making the system suitable for appropriately protected indoor or outdoor cold-plunge installations.
