Desiccant Dryers

Kaeser’s desiccant dryers provide reliable, energy-efficient compressed air drying for applications requiring low pressure dew points, including frost protection, sensitive manufacturing, and high-tech processing. The range includes compact heatless regenerative models, robust high-capacity systems, and advanced heat-regenerated designs using innovative technologies like Zero Purge and Closed Loop systems. Most units support pressure dew points down to –40 °C or even –70 °C, with intelligent controls and minimal maintenance requirements.
