We’ve used ADT across a few different projects. What keeps us going back is they actually know how our sites work, and work with us to find the best solutions.
Compressed Air Filters
Parker HDK Series High Pressure Compressed Air Dryer
- For applications requiring high pressure compressed air or nitrogen gas up to 50 barg (725 psig)
- With volume flows up to 1180m³/h (695 cfm)
- Pressure dew point options of -25, -40°C and -70°C.
Product detail
Everything you need to specify
The Parker HDK 50 bar range of high pressure compressed air dryers are designed to dry compressed air and gaseous nitrogen at high pressure levels of up to 50 bar 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 1180 m³/h @ 50 bar g, 35°C (695 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.).

Sizing and Selection
To ensure quoted air purity performance is met, a compressed air dryer must be sized correctly for minimum operating pressure, maximum inlet temperature and maximum inlet flow rate using the correction factors found in the Product Information Sheet.
For more information or a detailed discussion about your specific requirements please contact Parker or an authorised Parker distributor.

Why it matters
Clean, dry air pays back
The right filtration and drying shows measurable returns across the whole facility.
– Air loss
20-30%
Reduction in total air loss when leaks are properly sealed and repaired.
British Compressed Air Society
– ENERGY SAVINGS
~7%
Energy savings per bar of pressure drop recovered when filters are clean & dryers cleared
Hayley Dexis
– ELECTRICITY REDUCTION
10-15%
Electricity reduction as compressed air accounts for up to 30% of a facility’s total electricity bill
British Compressed Air Society
– INCREASED LIFESPAN
20-30%
Increase in the lifespan of pneumatic tools. Clean, dry air prevents this internal wear and tear.
