Superconduction liquid technology orginated from military project in the second war. In icy and snowy environment, runway freezes, so the takeoff and landing of airplane have accidents easily. Therefore, scientists developed superconduction liquid whose boiling point is 40C or so. So, only a few seconds later after evaporation terminal is electrified, superconduction liquid forms gas distributing in the vacuum copper pipe that is installed with radiator, transferring heat quickly. And the temperature of evaporation terminal and the terminal temperature are nearly equal. Its rate of heat conduction is higher than 95%. The machine is equipped with three protective fixtures including temperature controller, temperature fuse and overpressure valve, which is quite reliable. This machine can be placed on table and wall. Working voltage: 110V/220V. Power: 800.1200.2000W (three options).
