BP Series Dryers Produce 100% Efficient
Air Systems
Reduce Energy Consumption
BP Series dryers are 100% efficient at delivering full
supply-side compressor capacity. Therefore, users
benefit from the ability to purchase a less expensive
air compressor and a 20% reduction in compressor
operating costs.

Inlet-to-Outlet Performance
For decades, compressed air users have relied on
FS-Elliott to deliver technology that reduces the cost
of operation and improves the reliability of air-driven
processes. The BP Series dryers improve air system
efficiency by the use a dedicated axial blower, instead of
a percentage of dehydrated purge air, to regenerate the
off-line desiccant tower. ISO 8573.1 Class 2 (-40°F/-40°C)
dew point performance is guaranteed.

Eliminate Costly Compressed Air Loss
Global competition, spiraling energy costs, and the
challenge to “do more with less” require manufacturers
to closely examine operating costs. Compressed air
generation tends to be the most costly utility within a
facility. Eliminate air loss to align supply-side equipment
with demand-side requirements to optimize your air
system.

The FS-Elliott Products Guarantee
FS-Elliott guarantees that BP Series dryers will produce the design
dew point while operating continuously at maximum rated flow
(100% duty cycle) at CAGI ADF 200 inlet standards of 100°F
inlet temperature and 100% relative humidity at 100 psig.

How It Works
Filtered compressed air enters on-line desiccant-filled, drying
Tower 1 through Valve A. Up-flow drying enables the desiccant
to strip moisture from the air stream. Clean, dry compressed air
exits through E to feed the air system. Valve B on Tower 2 closes,
depressurizing the air to atmosphere through the muffler. Valves
D and F open and the heater turns on. The high-efficiency blower
draws ambient air and feeds it through the heater. The ambient air
stream passes through Valve F and flows downward through the
moist desiccant in Tower 2, collecting water vapor before exiting
Valve D. Once the desiccant is fully desorbed, the heater turns
off. Valve D closes and Tower 2 is repressurized. Once the energy
management system controller determines that Tower 1 is fully
saturated, Valve B will open and Tower 2 will be placed on-line to
dry the airstream and Valve A will close. Operations will switch and
Tower 1 will be regenerated.

Engineered Efficiency and Performance
Towers are filled with extra, high-grade
activated alumina to deliver superior
performance.
Soft-seated check valves provide for
tight shut-off and durability.
Standard Controls
• Tower Status
• Service Reminder
• Heater On
• Heater Temperature
• Desiccant Bed Temperature
• Failure to Switch
• RS 232

display is visible under any condition.
Low-watt density heater saves
energy and prevents premature
desiccant aging.
High quality pressure gauges

Inlet flow capacities shown in the Engineering Data Table have been established at an inlet pressure of 100 psig
(7kgf/cm2) and a saturated inlet temperature of 100°F (38°C). To determine maximum inlet flow at other conditions,
multiply the inlet flow from the Engineering Data Table by the multiplier from Table 1, which corresponds to your
operating conditions.
Dew Point
Outlet pressure dew point at rated inlet conditions of 100 psig (7kgf/cm2) and 100°F (38°C) saturated. Dew point
varies slightly at other conditions. Consult the factory to determine exact outlet pressure dew point at your
operating conditions.
