Ultra-compact and Efficient Temperature Control Technology


All our products are powered by our Proprietary, Patented, Ultra-compact and Efficient Temperature Control Technology which can achieve temperatures between 0°C – 60°C (32°F – 140°F) in seconds.

KÜLKUF is powered by patented ClimaCon® technology. ClimaCon® technology incorporates novel and efficient heat transport mechanisms that remove/add heat to provide thermal comfort to the body. It works on the principles of the Peltier effect, embedding a thermoelectric unit with the geometrically optimized heat sinks. A highly efficient thermoelectric unit accompanied by high heat transfer coefficients is the engine that drives the system.

Cyclist in Swiss

WOW, it stopped my night sweats and allowed for a good night sleep, just like you said it would.

Our bodies maintain a core body temperature

As you age, the ability to maintain and regulate body temperature can change significantly. When a hot flash occurs, your body works overtime to regulate its core temperature. KÜLKUF products are designed to reduce the stress on your body and help you cool down from within.

Patented solution and recognised by leaders

KÜLKUF is the only patented self-contained cooling product on the market that has been shown to reduce the body’s core temperature. An independent scientific study by the world-renowned Korey Stringer Institute demonstrated a significant lowering of the core temperature with the use of KÜLKUF.

Science for a better life, health and wellness

The wristband was initially designed for pro-athletes and gym-goers to reduce muscle soreness from heat exhaustion and increase stamina. After a few women approached us, we began months of testing KÜLKUF on menopausal women. The results were staggering. 9 out of 10 women said that hot flashes were eliminated within 60 seconds.

Menopause made easy & comfortable

Placing the smart cooling device on your wrist helps lower body temperature naturally. Cools down to 45°F in seconds and has 3 user-controlled temperature levels.
