FAQ
Got questions? We've got answers.
Why do I need a chiller and what is its temperature range?
Purpose: Automatic cooling and cleaning (filtration/ozone), so your ice bath is ready at any time without needing ice bags.
Temperature range: Cools down to 3°C and heats up to 42°C if needed (All-in-one system).
How much power does a chiller consume?
Consumption: OBERON chillers are designed for efficiency. A standard unit uses approx. 800W to 1.1kW during active operation.
Operation: Once the target temperature is reached, the device enters standby mode or significantly reduces power.
Do I need a chiller to keep the water clean?
Yes: Only the chiller provides the integrated filtration system (20-micron filter) and ozone disinfection to actively remove bacteria and debris.
Without a chiller: Standing water in a simple tub quickly becomes cloudy and unhygienic without chemical additives or manual filtering.
Advantage: With a chiller, the water remains crystal clear for weeks due to constant circulation and purification.
How often do I need to change the water without a chiller?
Frequency: Without a chiller and filtration, you should change the water every 3 to 5 days.
Reason: Static water without circulation and ozone cleaning becomes unhygienic due to bacteria, skin flakes, and sweat.
Pro Tip: With an OBERON chiller, this interval increases to 1 to 3 months.
Are there health risks with ice baths?
- Yes: Cold shock can put a significant strain on the cardiovascular system.
- Risk groups: People with heart problems, high blood pressure, diabetes, or during pregnancy should avoid ice baths.
- Safety: OBERON strongly recommends consulting a doctor before the first use.
- Rule: Never ice bath alone and increase duration slowly to avoid hypothermia.
DO YOU HAVE A GUIDE?
Which ice bath is perfect for traveling?
Model: The Lite Tub.
Benefit: It is the lightest and most mobile option, easy to inflate and pack down in minutes.
How fast does the water get cold with the chillers?
Cooling capacity: An OBERON chiller lowers the water temperature by approx. 3°C to 5°C per hour.
Efficiency: The insulated OBERON tubs help reach the target temperature faster and maintain it longer.
