Which Kelvin is right for you?

Electric whole-body cold, from −110°C to −150°C, with no liquid nitrogen on any model.

Made to order, with delivery and commissioning by our team.

Three Temperatures

Kelvin 110, 130, and 150

The number is the coldest set point the chamber holds. Choose by how cold you want to go and how many people you are running per day.

Kelvin 110 −110°C Lower running cost and a smaller power draw. The right call for a home or a compact recovery room.

Kelvin 130 −130°C The everyday standard for gyms and hotel spas, balanced for daily throughput at any size.

Kelvin 150 −150°C The deepest cold we build, for high-volume sites running back to back all day.
