The Frozin 0.8 HP Cold Plunge Water Chiller is a self-contained cooling system designed to bring up to 100 gallons of water down to 37°F and hold it there—without ice. Equipped with a 650 GPH circulation pump and an integrated 20-micron filtration system, it keeps your water consistently cold and clear between sessions. With standard 3/4-inch IN and OUT hose connections, it connects directly to the Frozin 400 and most other hard-sided cold plunge tubs without modification. Once set up, your tub is ready whenever you are.

Product Highlights
0.8 HP Compressor — Cools to 37°F
The 0.8 HP compressor is rated to cool up to 100 gallons of water to a minimum of 37°F. Once the target temperature is reached, the system maintains it automatically without requiring manual adjustment or ice replenishment.
Integrated 20-Micron Filtration
The built-in 20-micron filter captures particulates, hair, and debris as water circulates through the system. This extends the usable life of each fill and reduces how frequently the tub needs to be drained and refilled.
650 GPH Circulation Pump
The high-flow 650 GPH pump keeps water moving continuously through the chiller and back into the tub. Active circulation helps distribute cold water evenly and prevents temperature stratification.
Standard 3/4-Inch Hose Connections
The chiller uses standard 3/4-inch IN and OUT hose ports that connect directly to the Frozin 400’s built-in plumbing ports. No adapters or custom fittings are required for most compatible tubs.
Weather-Resistant Housing
The chiller unit is housed in a durable, weather-resistant casing suitable for placement in a garage, on a patio, or in a backyard gym environment. It is designed to operate in typical outdoor ambient conditions.
Always-Ready Operation
Because the chiller maintains your set temperature continuously, there is no warm-up or cool-down period before a session. Your tub is at the correct temperature whenever you are ready to use it.

Frequently Asked Questions
Is this chiller compatible with the Frozin 400 cold plunge tub?
Yes. The Frozin 0.8 HP Chiller is designed to connect directly to the Frozin 400’s built-in 3/4-inch IN and OUT hose ports. It is also compatible with most other hard-sided cold plunge tubs that use standard 3/4-inch plumbing connections.
How cold can this chiller get the water?
The chiller is rated to cool water to a minimum of 37°F (2.8°C). Actual cooling performance may vary depending on ambient air temperature, starting water temperature, and tub insulation.
How large a tub can this chiller handle?
The chiller is rated for tubs up to 100 gallons. For best performance, use it with a well-insulated tub in a moderate ambient temperature environment.
Does the chiller include a filtration system?
Yes. An integrated 20-micron filter is built into the unit. It captures particulates as water circulates through the system, helping to keep the water cleaner between full water changes.
Can I use this chiller outdoors?
Yes. The chiller’s housing is weather-resistant and suitable for outdoor placement in a garage, on a patio, or in a backyard setting. Avoid placing it in areas with standing water or direct exposure to heavy rain. In freezing ambient conditions, drain the system when not in use.
Does the chiller run continuously?
The chiller is designed to maintain a set target temperature. Once the water reaches the target, the compressor cycles as needed to hold that temperature. The circulation pump runs continuously to keep water moving through the filtration system.
How often does the filter need to be replaced?
Filter replacement frequency depends on usage and water quality. Follow the manufacturer’s recommended maintenance schedule included with the unit. Regular filter changes help maintain pump performance and water clarity.
What electrical requirements does this chiller have?
The chiller requires a standard grounded electrical outlet. Refer to the product documentation included with the unit for specific voltage and amperage requirements. Do not use an undersized extension cord.
The Frozin 0.8 HP Water Chiller is a reliable, self-contained solution for anyone who wants a consistently cold plunge tub without the ongoing effort of managing ice. If you use a hard-sided tub regularly and are ready to automate your temperature control, this is a practical and well-specified option.
