VPSA O2 scrubbers

VPSA technology (Vacuum Pressure Swing Absorption) is based on an energy-efficient, low pressure technique. A VPSA can both circulate and inject. During circulation, the residual oxygen level reduces along with the oxygen in the storage cell. Circulation is the most energy efficient mode for lowering the oxygen level in a storage area. So-called pull-down time is an indication of the time necessary for circulation to bring your storage cells to the required oxygen levels. During circulation, the VPSA reduces the oxygen concentration in the cell up to 30% quicker than when injecting.

The advantage of injection is that a cell can be kept at slight over-pressure so that ULO conditions (ultra low oxygen, <3%) are even possible in a storage area with a minor leak (ask your cool cell constructor or Van Amerongen for further advice). With the VPSA, you can switch between injecting and circulating and vice versa at any given moment.

Advantages of Van Amerongen VPSA O2-scrubbers;

The oil-free blower used in our VPSAs ensures that the active carbon is not contaminated by residual oil, resulting in its life-expectancy more than doubling. Furthermore, the active carbon filter is cleaned by means of a vacuum technique, allowing it to remain free of dirt and moisture. This makes our VPSA O2-scrubbers the most durable and energy-efficient!
