The Parker HDK 25 Bar High Pressure Compressed Air Dryer is engineered to provide reliable and efficient drying of compressed air and gaseous nitrogen at pressures up to 25 barg (363 psig). Designed for demanding industrial environments, the HDK series ensures consistent air quality by delivering multiple pressure dew point options of -25°C, -40°C and -70°C.
These high-pressure adsorption dryers are capable of handling volume flows up to 600 m³/h at 25 barg and 35°C, making them suitable for a wide range of high-pressure compressed air systems. The system is supplied with integrated Parker pre- and after-filters, ensuring effective removal of contaminants before and after the drying process to maintain optimal air purity and system reliability.
The HDK 25 bar dryers are delivered as a ready-to-install compressed air treatment package, complete with dew point control and mounted filtration. This integrated design simplifies installation while ensuring dependable drying performance and consistent compressed air quality in critical applications.
The system is commonly used in high-pressure industrial environments, including power generation and marine operations. Typical applications include diesel generator start-up systems in power stations, as well as marine and offshore uses such as tank ventilation, rope tensioning systems and generator start-up on offshore rigs.
Additional optional accessories are available to enhance system functionality, including start-up devices and high-pressure differential pressure gauges for the filters, allowing improved monitoring and control of compressed air treatment performance.
With its robust construction, integrated filtration and flexible dew point options, the Parker HDK 25 bar dryer provides a dependable solution for high-pressure compressed air and nitrogen drying applications.
