Pulsair: Pneumatic Impulse Mixing

Homogenizing large tank volumes, mixing-in additives during the production of lubrication oil and suspending solids in a liquid phase are typical applications for the pneumatic pulse-mixing technology of PULSAIR. The process, patented worldwide, is based on an injection of an adjustable pressure pulse underneath an accumulator plate, installed on the bottom of the mixing tank. The injected pressurized air forms a big air bubble, soaring within the tank and displacing the surrounding liquid. Meanwhile negative pressure is generated underneath the bubble, sucking the surrounding material. This produces in the tank a vertical flow directed upwards, adjustable according to the requirements by varying the pulse length and the pulse duration. Contrary to mechanical agitators the height of the tank is very marginal. No moving parts or shaft bearings are in the tank.
