Desiccant Compressed Air Dryers

Heatless Twin Tower Desiccant Dryers

Our HL heatless twin tower desiccant compressed air dryers are the perfect solution for removing water vapor from compressed air. Designed to perform consistently in the most demanding environments, our dryer range delivers key benefits such as low-pressure drop and reliable dew point performance. With a lower pressure dew point of up to -40°F or more, these desiccant dryers are ideal for even the most critical applications. By measuring actual pressure dew point, the PLC, which control all of the operations, will extend the dryer cycle reducing compressor energy, wasted purge air and valve wear and tear. Trust nano to provide you with the best solution for your compressed air drying needs.
