With a motor of 50 W is obtained 500 cbm/h air flow and a warming of the air by 14 degrees Celsius. By the heated air is heated again to get a highly efficient energy cycle. Construction heaters are used with different effects on the recorder due to the outdoor climate. Production involves the spinning of the body are continuously welded to a frame that holds together the structure. The fan is attached to a base plate with the brackets on the motor.
