Optional Accessories

Remote Monitoring System
Sends text messages or emails to up to six different mobile devices in the event of an alarm.

Outlet Pressure Valve
Builds up pressure within the dryer during start up to prevent damage from high flow velocities.

Differential Pressure Alarm Contacts
Provides a remote alarm signal for differential pressure across the pre or after filters.


Flexible and Functional
  • The fixed orifice is dependable and trouble-free and the optional Energy Saver dew point demand control system allows the flexibility to dial your dew point performance.
  • Advanced C1 controls allow you to monitor the operation of the dryer through an easy to read two line clear text display.


Unique Features
  • A high quality, molecular sieve desiccant bed is used is to ensure consistent dew point performance and long media life.
  • Includes a 0.01 micron high efficiency coalescing pre filter and a 1 micron particulate after filter mounted to the dryer. Filters are connected using high pressure 316 stainless steel pipe work and fittings, minimizing installation time and costs.


High Quality Construction
  • Rugged field proven anodized aluminum valve blocks eliminate leak paths and minimize pressure loss.
  • Primed and acrylic resin coated external surfaces for optimum corrosion protection.


Cost Effective Design
  • Efficient nano pre and after filters combined with high quality desiccant for low pressure drop and consistent dew point performance.


Customized to Meet Your Needs
  • At nano we understand every customer and every application is different. For this reason, we provide a wide range of available options to customize your dryer to your specific needs.


Advanced C1 Controls
A powerful controller monitors and controls each D-Series4 high pressure desiccant air dryer. The system monitors multiple inputs, showing pertinent data on the two line clear text display and controlling the fully automated drying and regeneration cycles. Input is via three buttons on the front of the NEMA-4X corrosion resistant enclosure.

An energy saving compressor synchronization contact is provided to stop the dryer from cycling when the compressor is not operating.

ES Energy Saving Option - The optional “ES” dew point demand system uses a reliable precision hygrometer to continually monitor the outlet dew point and extend the cycle for maximum energy savings. Includes real time outlet dew point indication on the panel, a 4-20 mA signal for remote monitoring and a high dew point alarm.


How It Works
The advanced nano D-Series4 high pressure compressed air dryers use the pressure swing adsorption principle to efficiently dry compressed air.

Incoming wet air passes through a high efficiency coalescing filter which removes particulate and aerosols down to 0.01 micron with greater than 99.9999% efficiency. The air is then directed to one of the two media vessels where water vapor is adsorbed by a two layer desiccant bed. The dry air then passes through the outlet check valve and a 1 micron particulate after filter to remove any media dust it may have collected.

Simultaneously, a small amount of the dry air (approximately 5% of the rated flow) is expanded to atmospheric pressure across an orifice and passed backwards through the off line desiccant bed for regeneration. Regeneration air is exhausted to atmosphere through a silencer.

The entire dryer operation is controlled by the advanced C1 controller which switches the flow from one vessel to the other every 10 minutes or as directed by the optional dew point demand system.
