Nano D5 Series Externally Heated
Twin Tower Desiccant Air Dryers

200 - 3,500 scfm
The nano D5 externally heated desiccant air dryers use an electric heater to heat the dry purge air used for regeneration, increasing efficiency and reducing the amount of purge air required. For consistent performance and cost-effective operation, these dryers are an excellent choice.

Nano D5 NEX Externally Heated twin tower desiccant air dryers reliably give you:
• advanced PLC controls allow you to monitor the operation of the dryer through an easy to use digital display.
• multiple thermocouples control regeneration and provide constant temperature.
• secondary heater contactor provides protection against overheating in the event of a primary contactor failure.
• visual alarm lights and step by step diagnostics simplify troubleshooting.
• rugged field proven digitally controlled dual acting high performance butterfly valves and stainless steel spring return wafer check valves ensure long operating life and minimum maintenance.
• insulated external electric heaters for efficient regeneration in all operating conditions.
• nano M01 coalescing pre filters and NHT M1 high temperature after filters with high quality hygroscopic desiccant ensure low pressure drop and consistent dew point performance.
• nano understands that every customer and every application is different. That is why we provide a wide range of available options to customize your dryer to your specific needs.
