Parker Zander HDK-MT High-Pressure Desiccant Air Dryer

Parker Zander HDK-MT High-Pressure Desiccant Air Dryer

For applications requiring high pressure compressed air or nitrogen gas up to 100 bar with volume flows of up to 650m³/h and pressure dew points down to -40°C.


The patent-protected HDK-MT concept is unique in its compact design. HDK-MT combines a vibration resistant, torsion rigid dryer unit, made of high precision vessel pipes and valve blocks, with a pre-stressed filling of highly active desiccant beads.

HDK-MT dryers come mounted with GH series filters, incorporating tie-rod fixed filter elements, which provide almost no target for torsional forces and abrasion. This provides a safe, reliable, and robust operation under pressure variations and constant vibration, typical for discontinuous operation in high-pressure ranges.

The choice of corrosion-resistant materials, like the hard-coated aluminium valve blocks, seamless vessels and stainless steel fittings make HDK-MT series dryers ideally suited for harsh environments.

Compact and robust in design HDK-MT dryers are ideally suited for installations in tight spaces, like compressor skids, as well as installations on ships, platforms, and in containers.


  • Dew-point control as standard
  • Compact, unique patent-protected design of the pressure envelope
  • Pulsation and vibration resistant
  • Corrosion-resistant
  • Small footprint
  • Simple servicing


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.
