D5 Blower Purge Desiccant Air Dryers

In a twin tower desiccant air dryer, one tower is on-line drying the compressed air while the other is off-line regenerating, which means it is eliminating the water vapor it has collected so it can be used to dry again. The two towers switch back and forth so one is always drying while the other is regenerating or in standby.
The nano D5 aircel branded twin tower desiccant dryers remove moisture from your compressed air system in the same way and to the same exacting standards of performance and reliability. The difference is how they regenerate and the amount of compressed air and/or power required to do so.

FEATURES

PLC controlled operation

• the dryer is operated by a robust and reliable PLC control system offering valuable features including ‘power on’, ‘hours run’ and ‘service required indicators’
• memory retention built into the PLC enables the controller to pick up where it left off in the drying cycle, ensuring consistently clean and dry air downstream
• compressor synchronization is a standard energy saving feature on HLA range which starts and stops the dryer with a signal from the compressor to eliminate purge loss when drying is not required
• NEMA 4 control panel

Low noise exhaust mufflers

• specifically designed to minimize the noise of
depressurization and purge exhaust
• high flow design improves regeneration

Low watt density heater (AEHD & ABP ranges)

• regeneration circuit is fully insulated for maximum
efficiency
• specifically designed for a long and dependable operating
life in harsh industrial environments

Secondary Heater contactor (AEHD & ABP ranges)

• provides protection against overheating in the event of a
primary contactor failure

Regenerative blower(ABP range)

• utilizes atmospheric air for regeneration
• easy maintenance and a rugged construction with TEFC premium motor that includes filtered air intake
• vortex regenerative blower (models 2500 scfm and below); centrifugal blower (models 3000 scfm and larger

pneumatically operated3-way valves

• three-way valves with stainless steel internals and Teflon® seats ensure reliable field proven performance
• used for inlet valves on models HLA 100 to HLA 800

high performance butterfly valves

• pneumatic actuators ensure precise proportional control and a bubble tight seal; no soft seals
• rugged stainless steel disk and Teflon® seats combined with a low pressure drop design
• used for inlet valves on models 1000 scfm and larger for HLA and AEHD ranges; 800 scfm and larger for ABP range

stainless steel spring check valves

• metal on metal seats for reliable operation, even high temperature operation
• provide worry-free operation and minimal maintenance

parallel cooling mode (ABP range)

• features a unique Parallel Cooling Mode to further reduce the heat and dew point spike prior to tower switch over. During the parallel cooling mode, both inlet valves are open and divert half-load to each tower, further cooling the previously regenerated desiccant bed with a larger volume of air.
• maximum savings with accurate dew point control

high quality construction

• ASME coded pressure vessels
• UL/cUL compliant
• activated alumina desiccant made in the USA
• lifting lugs and/or fork lift pockets on all products
