The density and thickness of the ice curtain affect the evaporation area.Only the tighter the ice curtain and the thicker it is, can it absorb moreOf water.When the wind passes through the ice curtain, the moisture evaporates and takes away the heat, and cool cold wind comes out.High- copper wire motor.The high- copper wire motor can guarantee the service life of the product and can be sustainableTime running air supply, strong horsepower, can blow the wind 5-6 meters local.Turbine 2-wheel structure.Turbine wind wheel design, large air volume, long air supply distance, effectively reducing wind and wind wheelThe friction, reduce the decibel generated by friction.Please allow 2-3cm differs due manual measurement.
