Nano D2 Series
Modular Desiccant Air Dryers

34 – 177 scfm
Designed for use in the compressor room, at the point of application or integrated into your original equipment, nano D2 modular desiccant air dryers are an effective solution to the problems caused by contaminated compressed air.

Nano D2 NDL desiccant air dryers reliably give you:
• more for your money - everything needed for installation is in the box
• moisture & particulate protection of your production process
• lower life cycle costs - low energy costs and simplified maintenance
• built in dew point monitoring (optional)
• space saving - models up to 24 scfm can be easily wall mounted
• safe and quiet operation
• flows 34 - 177 scfm at 100 psig operating pressure
• peace of mind - the most reliable product of its kind
• combined filter and desiccant cartridges can be serviced in less than 15 minutes

Nano 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 – 2010, Class 2 dirt (1 micron) and Class 2 water (-40°F pressure dew point).
Energy saving dew point monitoring option can save up to 60% during reduced inlet moisture loading.

(1) NDL 010 to 050 have push to connect fittings on the inlet and outlet. All other models have NPT(F) threaded connections
(2) at inlet conditions of 100 psig and 100°F and a -40°F outlet pressure dew point. For all other conditions refer to the correction factors above
(3) recommended for all applications. Required when dryer is to be installed immediately downstream of an oil lubricated compressor. To order with a pre-filter add “-F” to the model number (i.e. NDL 120-F)

Reliable High Performance

• Pressure is equalized before switching columns to ensure uninterrupted compressed air and consistent air pressure. Equalization also ensures long desiccant life due to minimized desiccant attrition.
• NDL 010 to 050 use integrated check valves and two pilot operated solenoid valves for proven performance and reliability.
• NDL 060 to 130 use four pilot operated solenoid valves.

optimum dew point performance
• Dryers are provided as standard set for a -40°F dew point. Optional dew point of -94°F is available.
• Air velocity and, therefore, air to desiccant contact time, is carefully controlled via a pressure maintaining device to ensure optimum dew point performance (optional).
D2 Desiccant Dryers Principles of Operation

System Performance

These advanced dryers use the pressure swing adsorption principle to efficiently dry compressed air. They use a heatless twin tower configuration housed in a modular design. Each column contains a unique (and patented) desiccant cartridge and outlet filtration. Wet air from the compressor aftercooler enters the dryer and is directed into column A. nano can provide F1 water separators and coalescing prefilters to ensure trouble-free operation for nano D-Series dryers. Air passes through the desiccant bed where moisture vapor is adsorbed. Then the dry air passes through a particle filter which retains any desiccant particles (< 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, reversing the function of each column and therefore ensuring the continuous supply of dry air.
D2 Desiccant Dryers System Performance
Energy Saving Dew Point Control Option
• with this option, a dew point sensor is incorporated into the dryer providing the ultimate in energy savings
• the outlet dew point is constantly monitored allowing the cycle time to be adjusted depending on the actual moisture load saving valuable purge air
• easily field retrofit; includes dew point display
• the -ES option reduces valve actuation increasing service life and includes an extended 5-year valve warranty
Floor or Wall Installation
• can be floor or wall mounted - simply by rotating the feet 90° (optional)
