The HBP Series
HBP Series Dryers produce 100% efficient air systems. HBP Series dryers improve air system efficiency by the use of 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.
Feature
- Soft-seated check valves for tight shutoff and durability
- Towers filled with extra, high-grade activated alumina
- Low-watt density heater saves energy and prevents premature desiccant aging
- High quality pressure gauges display left tower, right tower, and purge pressure
- NEMA 4 Construction
- Premium quality inlet switching/purge exhaust butterfly valves on 3” and larger (High-performance pneumatic angle-seated valves for smaller sizes)
- Optional EMS controlled Free-Air Supercharger uses A3 Purge TechnologyTM
Reduce Energy Consumption
As the air compressor is the most costly system component to purchase and, it uses more electrical energy than the rest of the system combined, it is wise to ensure that the smallest air compressor is installed. HBP 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 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.
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. Tower 2 (shown in regeneration mode) with valve (B) closed, depressurizes to atmosphere through muffler (C). Valves (D & 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. Valves (F & D) close and Tower 2 is repressurized. At a fixed time interval, 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.
