DÖLCO AT-150 Adsorption Dryer

Single-fan adsorption dryer in stainless steel housing — also usable at low temperatures

The AT-150 is the entry-level adsorption dryer in the DÖLCO range. Unlike condensation dryers, an adsorption dryer works chemically — via a hygroscopic sorption agent (silica gel rotor) that binds moisture from the process air and releases it via a separate regeneration air stream. The process also works at low temperatures (below 5 °C), where classic condensation dryers lose their performance. The AT-150 is therefore the choice for applications in cold storage, storage rooms with low base temperatures, or for drying requirements with very low residual moisture. The stainless steel housing makes the device durable and resistant to corrosion — even with permanent water contact.
