1. GENERAL INFORMATION
1.1 FUNCTIONAL DESCRIPTION
The desiccant air dryer is a pressure appliance designed to remove humidity from
compressed air.
It is made of two identical pressure vessels, which are filled with:
-aluminum oxide Al2O3 (for HGO models)
-molecular sieve
+
aluminum oxide (for HGL models)
Alumina is an adsorption-drying agent, which binds humidity.
Molecular sieve is an adsorption agent that binds to smaller molecules of water
vapour
which alumina can’t.
The columns are connected with two aluminium blocks. On the lower block are
located four valves and one silencer.
The valves force the air into the columns in order to dry the air in one vessel and
regenerate the alumina in the second one.
