We design, build and install plants for the pneumatic conveyance of solid materials. Applications we have tested range from so-called diluted phase plants, consisting of  single/double stage centrifugal ventilators with volumetric blowers, according to pressure and therefore distances to be covered.
The alternative, recommended for the conveyance of granules, is dense phase conveyance, requiring the use of thrusters and time-controlled compressed air. The best system solution is selected based on all the characteristics of the material to be conveyed.
