Using Pressure Swing Adsorption (PSA) technology, the Twin Tower Engineering regenerative air dryers are designed to maximize the efficiency of the drying process. Ultra-Dry compressed air dew points of -40°F to better than -100°F can be achieved. | Using Pressure Swing Adsorption (PSA) technology, the Twin Tower Engineering regenerative air dryers are designed to maximize the efficiency of the drying process.

Ultra-small desiccant compressed air dryers can be used for low-flow applications or with fractional horsepower air compressors. These units are heatless regenerative desiccant air dryers designed to produce low dew points. Extremely small footprint allows for packaging inside equipment cabinets or at point-of-use. | Ultra-small desiccant compressed air dryers can be used for low-flow applications or with fractional horsepower air compressors.

The Sullair DMD series is a lightweight modular desiccant dryer that offers unsurpassed installation flexibility. This lightweight modular dryer design brings a whole new concept in compressed air technology offering total installation flexibility to meet your specific needs. A small amount of the dried compressed air is used to regenerate the saturated desiccant bed by expanding air from line pressure to atmospheric pressure, removing the moisture absorbed by the desiccant material. Protection is built-in. Extruded aluminum housings that surround the dryers are fully protected from corrosion. | The Sullair DMD series is a lightweight modular desiccant dryer that offers unsurpassed installation flexibility.

The dual tower design of the DHL series dryers allows for continuous absorption of water from compressed air by using a desiccant bed. Drying is accomplished by passing wet compressed air through the desiccant bed of one tower where moisture is absorbed. Regeneration of the desiccant is accomplished without the use of heat. The wet bed is dried by diverting a small amount of dry air from the outlet at near atmospheric pressure. The purge flow rate is adjustable to suit the desired dew point. The dry air flows in a counter direction through the wet bed, sweeping all the water vapor previously absorbed by the desiccant. | The dual tower design of the DHL series dryers allows for continuous absorption of water from compressed air by using a desiccant bed.

The dual tower design of the DEX dryers allows for continuous absorption of water from compressed air by using a desiccant. Drying is accomplished by passing wet compressed air through the desiccant bed of one of the towers where moisture is absorbed. Regeneration of the desiccant is accomplished with the use of a low watt density heater. The heated air has a greater affinity to absorb moisture. When passed through the regenerating tower at near ambient pressure, the heated air flows in a counter direction through the wet bed, removing moisture previously absorbed by the desiccant. | The dual tower design of the DEX dryers allows for continuous absorption of water from compressed air by using a desiccant.

The dual tower design of the DBP, blower purge dryer, allows for continuous absorption of water from compressed air by using a desiccant. Drying is accomplished by passing wet compressed air through the desiccant bed of one of the towers where moisture is absorbed.
