The Parker HDK 25 bar range of high pressure compressed air dryers are designed to dry compressed air and gaseous nitrogen at high pressure levels of up to 25 barg (363 psig) reliably and efficiently to multiple pressure dew point options of -40°C, -25°C and -70°C (-40°F, -13°F and -94°F). HDK series dryers come equipped with integrated Parker pre- and after filtration and are capable of volume flows up to 600 m³/h @ 25 bar g, 35°C (353 cfm @ 725 psi g, 95°F).

Typical applications for HDK series high pressure compressed air dryers are in power stations (i.e. start up of diesel generators) as well as marine applications (i.e. tank ventilation, rope tensioning on off-shore rigs, generator start up etc.).
