Hitachi Industrial Equipment Systems Heatless Air Dryer HDK Series
Hitachi Industrial Equipment Systems
A heatless dryer that achieves a low dew point of -58/-73°C with a compact design.
Features - Two series with atmospheric pressure dew points of -58C and -73C The heatless air dryer uses a desiccant with excellent moisture adsorption performance, alternating between drying and regeneration processes to remove moisture content in compressed air down to PPM levels. It can be configured as a dry air system using a Hitachi oil-free screw compressor and filter, which do not use oil during the compression process. - Compact design for space-saving By adopting downflow drying, the chamber has been made smaller. Additionally, the vertical structure allows for a simple and compact silhouette, resulting in a smaller installation footprint and achieving space savings. - Highly expandable large control box There is ample space for the installation of various options such as dew point meters. Wiring installation is also easy.
