Continuous Dosing

from small to medium quantities

Continuous charging of powder into a process is a common requirement for many applications. From powder spray coating in the automotive industry, continuous charging of diamond dust into acid baths for wire production in

semiconductor manufacturing, to constant charging of an API into a continuous reaction system,  Dec have developed a  large range of solutions to meet such complex requirements.


Dosing can be effected either by repeating at a high frequency calibrated dose by using μPTS or the flexPTS or, by having a continuous powder flow when using PFL Powderflex.

Most of these systems are suitable to inject powder directly inline even when the process is done under vacuum or pressure.
