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 advantages

  • Reliable moisture protection
    KRYOSEC dryers use a high quality heat exchanger system with stainless steel plates to dry the compressed air. Accumulating condensate is efficiently separated at all operating phases via the integrated separator, while the ECO-DRAIN electronic condensate drain ensures reliable condensate removal without pressure loss.
  • Excellent performance in high ambient temperatures:
    KRYOSEC dryers ensure reliable drying even under the most demanding operating conditions. Along with defined cooling air flow, the generously sized heat exchanger and refrigerant condenser surfaces further help enhance performance.
  • Standard-compliant industrial quality:
    KRYOSEC dryers meet machine safety requirements in accordance with EN 60204-1. Safety features include a lockable ON/OFF switch as well as emergency shut down. High quality manufacturing and compact design make them ideal for use in areas adjacent to production and processing machines that require compressed air treated to high purity classes.

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

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

The Kaeser Condensate Filter (KCF) automatically removes lubricant from compressor condensate. This allows for easy and economical disposal of condensate in an environmentally responsible way. The low maintenance system requires no electricity for operation.
