1. Maximum Rated Inlet Flow assumes an inlet air pressure of 100 psig (7.0 barg) and temperature of 100°F (37.7°C).
2. Outlet flow is inlet flow minus average purge & depressurization loss over time.
3. With this option, a dewpoint sensor is incorporated into the dryer providing the ultimate in energy savings. The outlet dewpoint is constantly monitored, allowing the cycle time to be adjusted depending on the actual moisture load - saving valuable purge air.

Features

• Patented Combined Filter & Desiccant Cartridges:
  • Water separation, inlet and outlet filtration and desiccant are all integrated into a single cartridge (eliminates up to 3 external filters and drains). Built in inlet filter improves flow distribution and lowers pressure drop. Snow storm filled desiccant provides maximum adsorption capacity. Easy to replace cartridges simplify maintenance requirements.
• 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. The PLC remembers where it stopped in the drying cycle to ensure consistently clean and dry air downstream. A standard energy saving feature starts and stops the dryer with a signal from the compressor or point-of-use equipment to eliminate purge loss when drying is not required.
• Energy Saving Dewpoint Control Option:
  • With this additional option, a dewpoint sensor is incorporated into the dryer providing the ultimate in energy savings. The outlet dewpoint is constantly monitored, allowing the cycle time to be adjusted depending on the actual moisture load - saving valuable purge air.
• Floor or Wall Installation:
  • Can be floor or wall mounted - simply by rotating the feet 90°.
• Optimum Dewpoint Performance:
  • Air velocity (and therefore air to desiccant contact time) is carefully controlled via a pressure maintaining device to ensure optimum dewpoint performance.
• Constant Flow & Pressure:
  • Pressure is equalized before switching columns to ensure uninterrupted compressed air at all times with no changes in pressure.
• Reliable High Performance Valves:
  • Three way ball valves (NDL-010 to 050) or solenoid operated diaphragm valves (NDL-060 to 130) provide proven performance and reliability.
• Maximum Corrosion Protection:
  • Anodized extruded high tensile aluminum columns provide maximum protection for corrosive environments.

Benefits

• Guaranteed Performance:
  • The nano D-Series1 dryers have been 100% function and performance tested at the factory to ensure the highest standard of performance, delivering compressed air purity in accordance with ISO8573:1 - 2001, Class 2 dirt (1 micron) and Class 2 water (-40⁰ C pressure dewpoint).
• Reliable Operation:
  • High efficiency moisture removal and reliable operation with PLC controlled solenoid valves. Integral volumetric flow limiter prevents overflow ensuring consistent dewpoint performance. Condensate is automatically removed every cycle to eliminate possible carry over
• Quiet Depressurization:
  • Unique exhaust air silencers significantly reduce noise levels
• Energy Saving Design:
  • Integrated inlet & outlet filtration eliminates the need for external filter housings*. Advanced design limits regeneration purge air usage to approximately 15%. Energy saving dew point monitoring option can save up to 60% during reduced inlet moisture loading
• PLC Controls and Digital Display:
  • A clear digital display provides a full view of PLC operation and monitoring data
• High Quality Construction:
  • 100% tested for leaks, proper operation and dewpoint performance
• Easy to Install & Ready for Use:

• Easy to Maintain:
  • Patented, combined filter and desiccant cartridges. 12,000 hour and 5 year service interval kits. Built in inlet and outlet filters. No special tools required. No handling of loose desiccant. No handling of contaminants. Replace cartridges is less than 15 minutes
• Warranty:
  • Peace of mind - a 5 year warranty comes standard with every Nano NDL dryer

How the Nano NDL Works

The advanced nano D-Series1 dryers use the pressure swing adsorption principle to efficiently dry compressed air. They use a heatless twin tower configuration (see diagram opposite) housed in a modular design. Each column contains a unique (and patented) desiccant cartridge which incorporates inlet and outlet filtration.

Wet air from the compressor after-cooler enters the dryer and is directed into column A. Bulk liquids (water) and particles are removed by the filtration/separation stage, which is located on the inlet to the cartridge. Water is retained within the dryer until the column is regenerated, when it will be vented to atmosphere as it is depressurised. Following the filtration stage, air passes through the desiccant bed where any remaining moisture is adsorbed. Finally, the dry air passes through a particle filter, which retains any remaining desiccant particles that may have been carried through the system (<1 micron / ISO8573.1 class 2 for dust).

Simultaneously, a small amount of dry air is counter-flowed down through cartridge B and exhausted to atmosphere, removing the moisture and regenerating the desiccant.

The dryer is controlled by a PLC which periodically switches the solenoid valves when the compressor is running, reversing the function of each column and therefore ensuring the continuous supply of dry air.
