Abstract: The development of micro processed equipment is presented, with current exit for control of the speed of rotation of the fan motor of the system of forced air, using investing of the frequency. Through programming (software IHM.EXE), the user can define the mass to be cooled, in kilograms of the product. The equipment calculates through a programmable polynomial previously defined, the frequency of operation of the investor which corresponds to air specific flux, within the limits of the project. The equipment was installed in a forced-air cooling system, being considered by the calculation in useful mechanical power, the energy savings is estimated at around 82% with a rotation equivalent to 56% of the fan nominal, thus providing significant savings in system operating costs.
