KRYOSEC: a small refrigerated air dryer for compressed air


Compact and reliable operation for optimal moisture removal

KRYOSEC compact refrigerated dryers* deliver outstanding performance with "Made in Germany" industrial quality and reliable moisture protection in ambient temperatures up to +122 °F. Lower pressure losses are thanks to the stainless steel heat exchanger system while the easy maintenance design ensures economical operation. Thanks to their compact design, they're always a great fit directly where they're needed – under machine stages, work platforms, or even mounted on the wall (TAH series).

  • Reliably dry compressed air from 12 to 159 scfm
  • Working pressure up to 232 psig
  • Options: ECO-DRAIN electronic condensate drain and/or electronic thermostat for pressure dew point warnings – both with floating alarm contacts

Your benefits:

  • Reliable moisture protection
    KRYOSEC dryers use a high-quality heat exchanger system with stainless steel plates to dry the moist compressed air. Accumulating condensate is efficiently separated in all operating phases via the integrated separator and then reliably removed via the ECO-DRAIN electronic condensate drain.
  • Dependable performance, even in high ambient temperatures:
    KRYOSEC dryers ensure reliable moisture removal, even under the most demanding of operating conditions. Performance is also enhanced by the defined cooling airflow plus the combination of a generously sized heat exchanger and refrigerant condenser surfaces.
  • Standard-compliant industrial quality:
    KRYOSEC dryers comply fully with the safety requirements for machines in accordance with EN 60204-1. Safety features include a lockable ON/OFF switch and a power supply isolating device. High-quality manufacture and a compact design make KRYOSEC dryers ideal for use within a decentralized installation – positioned directly alongside production and processing machines that require compressed air treated to the highest purity classes.

* Dryers from this series contain the fluorinated greenhouse gas R-513A.

The perfect partner: the KCF oil/water separator
KCF condensate filters

Our tip: Take advantage of cost-effective, legally-compliant treatment of condensate before drainage into the regular wastewater system with KCF oil/water separators.
