Parker HDK-MT Series high-pressure desiccant air dryers are designed for reliable treatment of high- pressure compressed air up to 350 bar. The patent-protected concept of HDK-MT series combines a compact, vibration-resistant and rigid design. Constructed with corrosion resistant materials, such as hard-coated aluminum valve blocks, seamless vessels and stainless steel fittings, the HDK-MT Series dryers are perfectly suited to maximize efficiency by offering leak-free operation in harsh environments.
Without proper filtration, desiccant air dryers will not operate properly. Desiccant dryers are designed to adsorb vapor from compressed air they are not designed for liquid. When liquid, especially oil, is allowed to enter the desiccant chamber, it coats the desiccant material preventing proper absorption. Oil coated desiccant cannot be regenerated, and must be replaced.
Equipped with high pressure pre and after filters, the HDK-MT Series high-pressure desiccant air dryers reduce compressed air impurities to a minimum. The grade XP coalescing pre-filter is installed at the inlet of the dryer. It protects the dryer by providing particulate removal down to 0.01 micron, including water and oil aerosols at 99.99999% ef ciency (maximum remaining oil aerosol content: 0.01 mg/m3).
To protect downstream equipment from desiccant dust, a particulate after-filter is mounted at the dryer discharge. The grade ZP after-filter traps any remaining solid particles up to 1.0 micron with an efficiency of 99.9999%.
HDK-MT Series dryers come equipped with Ecotronic dew-point dependent control. Regeneration requirements are dependent on ow, pressure and temperature. The Ecotronic system allows the cost of drying compressed air to be matched exactly to your plant conditions. Ecotronic controls the drying cycle by continuously reacting to the loading which the dryer is operating under and minimizes the energy input required. As dryers rarely operate at full rated capacity all of the time (eg. during shift work and periods of low demand), this energy management system can provide considerable savings.
