  • BP Series Blower Purge Desiccant Compressed Air Dryers

  • BP Series Dryers Produce 100% Efficient Air SystemsFor 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.

    Reduce Energy ConsumptionBP 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.

    Eliminate Costly Compressed Air LossGlobal 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 WorksFiltered 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

    Soft-seated check valves provide for tight shut-off and durability.

    Towers are filled with extra, high-grade activated alumina to deliver superior performance.

    Low-watt density heater saves energy and prevents premature desiccant aging.

    Standard Controls• Tower Status• Service Reminder• Heater On• Heater Temperature• Desiccant Bed Temperature• Failure to Switch• RS 232

    High quality pressure gauges display left tower, right tower and purge pressure.

    Function indicator LEDs allow for easy monitoring.

    The control panel and terminal box are built to NEMA 4 standards.

    Premium quality inlet switching/purge exhaust butterfly valves for long life on 3” and larger. (High-performance pneumatic angle-seated valves for smaller sizes.)

    High-capacity blowers are quiet and energy efficient.

    Easy-view vacuum fluorescent text display is visible under any condition.

    Engineering Data: 500-4300 scfm*

    *Consult factory for larger models.1 Performance data per CAGI Standard ADF 200 for Dual-Tower Regenerative Desiccant Compressed Air Dryer. Rating conditions are 100°F (37.8°C) inlet temperature, 100 psig (6.9 bar) inlet pressure, 100% relative humidity, 100°F (37.8°C) ambient temperature,

    and 5 psi (0.35 bar) pressure drop.Dimensions, Weights & Inlet/Outlet Connections are based on standard pre-piped filter options.

    Inlet FlowInlet 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.
