Compressed Air technology
Dryers
Water out. Dew point under control.

How it works
Compressed air dryers remove water vapour to prevent corrosion, freezing and product contamination. Refrigerated dryers suit general plant air; desiccant dryers reach much lower dew points.
Refrigerated dryers chill air to condense water. Desiccant dryers adsorb moisture onto media that is regenerated by purge air, heat or blower.
Performance range
Refrigerated ≈ +3 °C (+38 °F) pressure dew point; desiccant down to −40 °C/°F or lower
Typical industry range. Exact capability is model specific, see each model’s curve.
