PRODUCT USER MANUAL
RD SERIES DRYER
2.1 INTRODUCTION
The Sullair Non-cycling Refrigerated air dryers are
designed for constant full load operation. They use
specially designed heat exchangers with integrated
components to provide consistent dewpoint and
trouble-free service for years to come.
The dryers remove the moisture, from the
compressed air stream. By using basic refrigeration,
the hot saturated air is cooled in the highly efficient
heat-exchangers and the moisture is condensed and
removed. Additional filtration eliminates other
contaminants and particles.
Water (moisture) is one of the greatest enemies of air
tools and piping. Left untreated in the compressed air
stream, this moisture will deteriorate the tools,
equipment and piping with corrosion, pipe scaling,
freezing and a host of other problems that will
diminish the life of your entire compressed air
system. With a Sullair refrigerant dryer, you can be
assured of clean, dry air with consistent dewpoint
between 36 and 40°F / 2 and 4°C. The unique three-
in-one heat exchanger combination—
• Air to Air (pre-cooler/re-heater Heat Exchanger)
• Air to Refrigerant (high efficiency Heat
Exchanger)
• Integrated Separator (located at the coldest point
to maximize moisture extraction)
heats up the exiting air, thereby eliminating the
chances of freezing even in relatively cooler ambient
conditions. Warm dry air will not affect the piping nor
the tools and the result is extended tool life. In
addition, applications that require clean dry air can
rely upon Sullair’s non-cycling refrigerated air dryers
to provide dry air at full load continuously.
2.2 SPECIFICATIONS
Pay attention to the Minimum and Maximum
operating conditions before installing and operating
the dryer.
RD dryer capacities are designed in accordance to
CAGI standards. Variances from standards will
directly affect performance.
If your application does not match the above criteria,
contact your Sullair distributor and they will be able to
provide the right dryer for your application.
