The Air Squeezing Bottle is an insulated container that eliminates condensation on the glass using dry ice. It works by fixing water in a cooling coil, which is cooled indirectly to 0 degrees Celsius by -78.5 degree Celsius dry ice. The coil consists of brass pipes with NBD Nano superhydrophobic coating inside, allowing the air to be blown by a fan and cooled below its dew point temperature. As a result, the air condenses into water and drips out over the cooling coil. Powered by a rechargeable 12V-2.5A battery (INPUT: 100-240V), this compact bottle offers an airflow of 60CFM (1.7m3/min) at 5W, maintaining a temperature range of 20-30 degrees Celsius and relative humidity of 70%. It can accommodate 150g dry ice input per hour and has a fixed water capacity of 1.8 liters for the cooling coil. The bottle's water output performance is approximately 200-300ml per hour, with dimensions of 175mm(W)×175mm(D)×293mm(H).
