This animation illustrates the elegance and simplicity of the ISL system with no mechanisms or parts in the powder flow. There is no actuator to wear, abrade or fail and the system is fail safe. The ISL Transducer control system automatically varies the valve aperture, operating mode and product flow rates to ensure accurate continuous and batch control; irrespective of varying product characterisitics or even totally different products. The system is essentially maintenance free with only a handful of parts and assembly/dissasembly in seconds ensuring no downtime for cleaning or product changes.
