PRO Chiller
Powered by 1.0HP and bacteria killing UV-C Sanitation. With an industry leading 5-Micron Filtration, keep your water cleaner for longer. Built on wheels for effortless mobility and reduced exposure to debris and moisture. Water temps as low as 36°F.
Ultraviolet light is used as a form of water sanitation.
Disinfection and Sterilization: UV light is effective at killing or inactivating microorganisms such as bacteria, viruses, and mold. In cold plunge chillers, UV lamps are often incorporated into the filtration system to disinfect the water. This ensures that harmful pathogens do not grow or thrive in the cold water, making the experience more hygienic and safe.
Prevention of Biofilm: Cold plunges can develop biofilms — slimy layers formed by bacteria. These biofilms can affect water quality and even clog filters. UV light helps to break down and prevent the formation of these biofilms by killing the bacteria that contribute to their formation.
Maintains Water Clarity and Freshness: By killing microorganisms and preventing the buildup of organic matter, UV light helps keep the water clear and fresh, improving the overall experience of the cold plunge.
UV light in cold plunge chillers helps maintain clean, hygienic water. It enhances safety, improves water quality, and ensures the longevity of the system by preventing the growth of harmful microorganisms.
Able to reach temperatures as low as 36°F as quickly as 3-5 hours from setup. Once initial temperature is reached, effectively maintains temperature with twice the cooling speed of a 0.5HP Chiller.
A micron rating refers to the size of the particle a filter can effectively capture. A 5-micron filter can capture particles such as dirt, sand, debris, and microorganisms that are 5 microns in size or larger. It helps keep the water clean by removing visible debris, larger microorganisms, and particles that might affect water quality or comfort.
The smaller the micron #, the finer the debris being captured from entering your cold plunge.
Built on wheels, off the ground for effortless mobility and reduced exposure to debris and moisture.

Cooling Power
Cooling rates are fastest when water temperature is at its highest. Chiller will cool faster earlier and slower as it's reaching 40°F.
Ambient temperatures have a dramatic effect on cooling rates. Chillers placed indoors will cool faster than outdoors especially during warmer months.

Top 3 Lessons I Wish I Knew Before Purchasing My Cold Plunge System
How often do you want to change your water?
Possibly the most important things to consider when buying a cold plunge.
Water changes can be time-consuming, messy and disruptive, turning your plunge into a chore instead of a habit. Pay attention to HP, invest in UV-C or Ozone sanitation, use Sirona Sanitizer & Oxidizer and choose the right filter with a low micron rating.
With the proper setup, you’ll be changing your water every few months instead of every week—and that could be the difference between staying consistent or giving up on your routine.
There are other layouts aside from the traditional tub.
I upgraded from a $99 pod to a $1k tub, thinking it was the natural next step. Instead, I found it uncomfortable: numb toes, difficulty breathing and overall frustration not being able to withstand the cold temperatures I once could.
Finding the barrel as an option changed everything. Plunging upright feels instinctively better, unlike the tub that requires more of a lay down approach similar to bath time. If you’ve been using a pod and are ready to level up, the barrel is definitely worth considering.
Why U.S. based customer support actually matters.
Whether it’s fixing air lock after replacing a filter or requesting a component under warranty, I learned the hard way how critical it is to have live support. Do yourself a favor and call before you buy and make sure someone actually picks up.

Frequently Asked Questions
How easy is HydroTub to setup?
The HydroTub takes 5 minutes to setup. It's as easy as opening the package, removing the plunge from the carry-all bag and inflating with the included pump.
How easy is the Chiller to setup?
The Pro Chiller comes with all necessary parts and instructions for setup. A set of tubes connects the Pro Chiller to your Cold Plunge. The UV Chamber and Filtration are built inside the side compartment of your Chiller. Setup can be as fast as 90 seconds (please refer to our youtube video).
How often should I change the filter?
For reusable filters, we recommend cleaning once a week to prevent debris build up.
For 5 micron replaceable filters, we suggest replacing every 2-4 weeks based on water quality.
What are the power requirements?
Our OSONE chillers use a standard 110V outlet. We recommend using an isolated outlet, if possible.
Can the products be outdoors?
Yes, the HydroTub is built for indoor/outdoor use. We recommend placing under a covered area, such as a lanai, to prevent direct sunlight and exposure to the elements.
The Chiller can also be outside and we also highly recommend putting under cover. For longevity purposes, all items should be under a covered area to prevent direct sunlight and direct exposure to the elements. Outside temperature directly affect cooling times and chiller output so keep this in mind during setup. Chillers operating indoors have proven to use less energy and are better protected from the elements and can increase longevity.
Can I buy the HydroTub separate from the Chiller?
Yes, you are able to buy all of our products a la carte. We have customers who have bought the HydroTub during the cooler months and come back to purchase the Chiller for the summer months.
