DPB Series - Global Air Treatment Dryers (500 – 4300 scfm) The DPB Series process design offers the end user the opportunities to significantly reduce the energy costs associated
with achieving a reliable -40°F (-40°C) pressure dew point. This is achieved by eliminating or reducing purge air
requirements (compressed air utilized to regenerate desiccant beds) typical of other desiccant dryer designs.
Inlet Flow capacities have been established at an inlet pressure of 100 psig (7 kgf/cm2), and a saturated inlet
temperature at 100°F (38°C). To determine maximum inlet flow at other conditions, multiply the inlet flow from the
Specifications Table by the multiplier from Table 1 that corresponds to your operating conditions.
Dew Point: Outlet pressure dew point at rated inlet conditions of 100 psig (7 kgf/cm2) and 100°F (38°C) and 70°F (21°C)
atmospheric dew point is -40°F (-40°C). Dew point varies slightly at other conditions. Consult factory to determine exact outlet pressure dew point at your operating conditions.
Outlet Temperature at normal rated conditions (after temperature spike) is 127°F (53°C). Outlet temperature
varies depending on inlet temperature and pressure.
Consult factory to determine exact outlet temperature at your operating conditions.
Available voltages: 460V/3ph/60Hz, NEMA 4 enclosure

RNC Series refrigerated air dryers are engineered to benefit you today and tomorrow from the tradition of durability that is Gardner Denver.
Quality components and engineering excellence meld to ensure you of a stable 38°F +/-4°F
pressure dew point. These exclusive compressed air preparation packages combine reliability, cutting-edge design, and innovative packaging into a single space saving unit. The air quality delivered from an RNC Series dryer may define the difference between moderate and superior results from your plant’s processes or systems.
RNC Series dryers benefit you with:
1. Four levels of Intelligence Controller (I-Controller) packages to allow you to
customize the RNC Series dryers to meet your specific requirements.
2. Select Heat Exchanger arrangements to ensure you get the right combination
of value and efficiency in every size.
This secures your investment today and tomorrow with energy efficiency.
3. Combination Separator/Filter that incorporates our 99% efficient 3 micron
Grade B elements. This ensures you of consistent water removal (especially under low flow conditions).
Many years ago, Gardner Denver set the standard for energy efficient rotary screw air compressors. The goal was to combine the rugged simplicity of the screw compressor with the energy efficiency of the big old reciprocating compressors. We called the new technology the TurnValve™ and introduced it with the Electra-Saver® Air Compressors. Now, almost half a century later, the legendary Electra-Saver® is still one of the most energy efficient designs your money can buy for plants with changing air demands.
Today, Gardner Denver continues that tradition of providing energy saving solutions to help you increase profits and reduce power costs. Challenges for energy efficiency and dew point stability are answered with a technological breakthrough in energy efficient refrigerated air dryer design. We call this energy saver the RSD Series and it is unlike any energy efficient compressed air dryer technology you have ever seen. Only the RSD Series Digital Scroll Refrigerated Air Dryers offer you.
Dew Point Stability: 38°F from 0%-100% of rated flow
Energy Savings: up to 91% power reduction
