nano dryers – D1 & D2 in detail
patented combined filter & desiccant cartridges
• built in inlet water separator (D1 only) eliminates the cost and pressure drop of installing a
separate inlet filter in small oil-free compressor applications*
• built in outlet filtration to eliminate the cost, pressure drop and maintenance associated with
a separate after filter
• high density filled desiccant provides maximum adsorption capacity
• easy to replace cartridges simplify maintenance requirements (models NDL 010 to 130)
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 which 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 dew point control option

maintaining device to ensure optimum dew point performance (standard on D1, optional on
D2 & D3)
constant flow and pressure

* applies to the D1 only. For oil flooded compressors, an upstream nano F1 M01 coalescing pre-filter is required
system performance
These advanced 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 an inlet water separator (D1 only) 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 pre-
filters to ensure trouble-free operation for nano D-Series dryers.
D1 only: Bulk liquids (water) and particles are removed by the separator on
the inlet of the cartridge. Water is retained within the dryer until the column
is regenerated, when it will be vented to atmosphere as it is depressurized.
D1 & D2: 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.
B 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.

We’ve designed the D3 with simplicity of service in mind. As standard, the
columns are high density filled and include a built in 1 micron after filter
for reliable downstream air quality. For even greater ease of service, pre-
filled and pre-assembled desiccant / after filter cartridges are available
as a time saving option.
reliable high performance valves
Inlet, exhaust and outlet air are controlled using coaxial flow valves
integrated into the upper and lower manifolds. The valves provide
unrestricted flow capacity and are designed for durability, ease of
maintenance and long service life.
