Desiccant dryers

Desiccant dryers for frost protection, including high-tech applications

Desiccant dryers from Kaeser Kompressoren achieve pressure dew points down to −94 °F. 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 424 cfm and above, can also serve as dependable redundancy systems for our extremely economical HYBRITEC combination dryers.

For compressed air demands of 622 cfm and higher, our heat regenerative desiccant dryers feature an efficient and space-saving unit design.
