Heated purge regenerative desiccant air dryers use less air than the heatless variety in addition to heat, which helps the air carry away more water as it passes through the saturated desiccant.==Best Compromise==Heated blower purge regenerative desiccant air dryers use air from outside the dryer that is heated and sent through the water-saturated desiccant for drying. | |||
