TSUNAMI Membrane Dryers
Tsunami Membrane Dryers provide an economical solution for supplying clean, dry air without the need for electricity. The molecular makeup of the hollow tubes allows water vapor to pass. The greater the pressure differential between the inlet nad outlet pressures, the drier the air downstream.
The 2-Stage Membrane Dryer includes a water separator, oil coalescing filter, and membrane dryer. Incoming air enters the 1st and 2nd stage filters where liquid water, oils and particulates are removed. Then, the air enters the Membrane Dryer where water vapor is removed from the air.
How it works:
1. The molecular makeup of the hollow tubes allows certain gases to pass through the membrane quicker than the desired gas.
2. As compressed air travels through the hollow tubes, water vapor passes through the membrane pores.
3. The water vapor collects within the housing until it is removed.
4. A fixed orifice at the bottom of the hollow tubes allows dry air to pass up the housing, around the hollow tubes, to sweep the water vapor out the sweep holes at the top of the housing.
