The Drying Process The Regeneration Process
Wet Incoming Air
— supply air from compressor or
from the compressor system
Dry Outgoing Air
— air that has had the water vapor
removed
Dry Outgoing Air
— small amount of dry air used to
“sweep” or regenerate the towers
Wet Discharge Air
— water vapor which was removed
during the drying cycle
The Tsunami Regenerative Dryer
Product Description
The Tsunami Regenerative Dryer System uses the latest technology to provide your facility with the cleanest, driest compressed
air available. Our systems, unlike some of our competitors, are complete systems. This includes the Tsunami water separators
and Tsunami oil coalescing filters. We use Moisture Minder® automatic piston drains to assure proper draining of water and oils
before the dryer.
We can configure systems to provide very low dew points (down to -80° F) or very low relative humidity (down to .01%) with very
low sweep rates. Flow rate and sweep rate determine the quality of your compressed air.
• This technology functions by passing wet, dirty compressed air through the Tsunami water separator which removes bulk
water and oil down to 10 microns, then the air passes through the Tsunami oil coalescing filter which further removes oil and
particulates down to .01 micron.
• This pretreated air enters the dryer and passes through one or more desiccant canisters.
• These canisters are filled with a molecular sieve bed which is under tight compression, so there is virtually no movement or
banging together of the beads to cause material break down. Our desiccant media is also encapsulated in a 10 micron filter
bag which eliminates the possibility of desiccant carryover downstream.
• As the wet air passes through the towers, the molecular sieve draws the water vapor in while under pressure. At the same
time, one or more towers are depressurized. These towers discharge water vapor through the mufflers below those towers
with the use of sweep air.
• The PLC controller sends out a pilot signal for an internal spool to shift, which switches the flow of air through the towers.
• This switching of tower operation now allows wet, incoming air to flow through a new or previously dried tower. We take
a little air from the dry, outlet flow and direct this air backward through the wet towers via a very small orifice in the
regeneration valve. (This is referred to as sweep air or the regeneration process). This dry flow of air through the wet beads
will dry them out so they are ready for a new cycle. It’s like changing your desiccant every few minutes. Our system assures
a continuous flow of clean, dry compressed air for your needs.
