The Importance of Clean,
Dry Compressed Air
Water jeopardizes everything you want your compressed air system to do. Failure to remove this water ruins
product and fouls process. That’s why it is vital to have a reliable air treatment system in place to help protect
your equipment and your operations.
Sullair Refrigerated Air Dryers reliably remove harmful moisture and contaminants from compressed air,
helping protect your compressed air system, machinery and downstream tools.
How?
1. Saturated compressed air enters the system and
is precooled in the air/air heat exchanger.
2. Then, precooled air moves downstream through
the air/refrigerant heat exchanger. The heat
exchanger’s vertical profile design reduces
condensed moisture by nearly 99% using
gravitational force.
3. To reliably prevent separated droplets from re-
entering the airstream, condensate collects in
a large reservoir with subsequent recirculation
where flow velocity is significantly reduced.
4. Accumulated condensate is then discharged from
the dryer via drain.
The dried, cold process air passes back through the
heat exchanger to be reheated — reducing relative air
humidity and recovering up to 60% cooling capacity.
Non-Cycling
Non-Cycling dryers are ideal for running at full
load because they maintain a constant energy
consumption no matter the flow and air demand.
Sullair non-cycling dryers use a hot gas bypass to
maintain a stable dew point in varying operating
conditions and control the amount of refrigerant
circulating through the dryer.
