The Frostcore Ice Bath Water Chiller lets you skip the bags of ice. Set your target water temperature and the chiller holds it, so every plunge is the same. It works with the tub you already have and plugs into a standard household outlet.
Features
- No ice: set any temperature from 36°F to 86°F and the chiller holds it.
- Works with most tubs: standard bathtubs, soaking tubs, and inflatable tubs of about 80 to 132 gallons. Keep the inlet and outlet pipes apart and off the bottom and walls.
- Cooling: a built-in circulation pump and compressor can cool water to about 37°F (3°C) in roughly 4 hours.
- 3-stage filtration: a 40 micron filter catches hair and debris, a 20 micron filter removes fine sediment, and an ozone generator sanitizes the water.
- WiFi control: use the control panel or the phone app over 2.4GHz WiFi, with schedules, a lock, disinfection, and status monitoring.
- Outdoor ready: GFCI plug, IPX4 splash resistance, and a UV-resistant housing. Do not run it when the air is below 34°F.
- Setup: inlet and outlet pipes and camlock couplings included. Let the unit rest 3 to 4 hours before first use, then install in as little as 5 minutes.
