Adsorption compressed air dryer SULLAIR EUROPE
40 m3/h - 2040 m3/h

Technology : Adsorption Dryers.
Operating principle: Designed for extracting humidity from compressed air, these dryers consist of aluminium columns each of which contains two twin chambers filled with a desiccant agent which dries the compressed air crossing over it. When a chamber is in service (drying phase), the other is in regeneration mode.

Flow rates treated:
From 40 m3/h to 2040 m3/h
Values given for a pressure of 7 bar and aspiration at 1 bar and at 20°C.
Pressure Dew point:
- 40°C as standard (SM and SMH models)
- 20°C optional (SM230 to SM1200 models only)
- 70°C optional (SM and SMH models)

Standard equipment:
High resistance extruded aluminium construction. Humidity indicator for monitoring the quality of air supplied. Fast re-pressurisation valve providing easy commutation and improving reliability.

Regeneration method: By pressure variation (SM models) and temperature variation (SMH models): the saturated desiccant agent is regenerated using a small quantity of the treated compressed air (SM models) with an additional heat contribution through heating elements (SMH models only). The dilatation of that warm air which is changed from the circuit pressure to atmospheric pressure provides the means for extracting the humidity absorbed by the desiccant agent and thus for regenerating it. The heating elements (SMH models only) provide the means for significantly reducing the quantity of dry air used and at the same time the dryer's operating cost.
