Desiccant dryers

Desiccant dryers for frost protection, including high-tech applications

Desiccant dryers from Kaeser Kompressoren achieve pressure dew points down to −70 °C. Benefit from reliable anti-frost protection for your control valves and lines and compressed air drying for sensitive processes at minimum cost – thanks to standard-equipped, high-quality compressed air filters and efficient, energy-saving controllers. Alumina desiccant ensures particularly high levels of operational reliability.

Heatless regenerative desiccant dryers are perfect for supplying low-level compressed air demand and, when it comes to units of 12.0 m³/min and above, can also serve as dependable redundancy systems for our extremely economical HYBRITEC combination dryers.

For compressed air demands of 17.6 m³/min and higher, our heat regenerative desiccant dryers feature an efficient and space-saving unit design.
