Tips and tricks

Installation Tips:
  • The cooling power of the CoolCube is guaranteed. The effect on the water temperature is dependent on a number of factors such as Starting temperature, ambient temperature, water flow volume, installation location, lighting systems, surrounding heat sources, etc. Please take this into account when installing the machine.
  • The computer in the CoolCube will remember your settings, even when the power is switched off. So you can use a simple time switch, or any similar solution to cool your icebath at set times, or remotely.

How do I start using a CoolCube™?

Simply connect the tubes between the pump and your CoolCube, put the pump in the bath/tank/small pool (under water) and turn your CoolCube™ on. It’s that easy!
It depends on the outside temperature, but usually a CoolCube™ needs 2 to 4 hours to reach freezing cold water. Temperatures as low as 1-2 degrees Celsius are simple to achieve.
Yes it can! Depending on the outside temperature it can reach 36-38 degrees Celsius which is similar as normal hot-tub-temperature.
Yes it will.
It consumes about the same as a fridge/freezer combination. Even if you practice daily, your electricity bill will not drastically increase.
  • Always make sure you have a viable method to regain normal body temperature after an ice-bath. This can be a normal hot shower, a sauna or the sun (if the outside temperature is over 30 degrees Celcius).
  • Study ‘Cold Therapy’. The more you know about Cold Therapy, the better. For us there has been only one mentor; that is Wim Hof.
  • The weight of a CoolCube™ is significant; the CoolCube™ C2 ways up to 60 kilos. The CoolCube™ C3 is over 80 kilos. Make sure you prepare the location of your future CoolCube™.
  • If you have little to none experience with ice baths and Cold Therapy, start slow. Meaning, max 2 minutes submerged.
  • Although the pump is vigorously tested and safe for use, we still recommend you disconnect it from your power-supply as to avoid unnecessary risk of injury.
  • Again; study Cold Therapy before you start practicing.
The Coolcubes are not designed to be exposed to the elements year-round. In fair-weather contditions having the unit outside is no problem, but exposure to heavy rain, mud or freezing temperatures during winter is not recommended. The Coolcubes are delivered with a -very minimlistic- plastic cover which can be used to for some protection from the rain.
