A2.1 COLUMN / DESICCANT REMOVAL
Remove outlet head assembly and upper gasket. Remove upper column pads and remove
desiccant by either inverting dryer or by means of an industrial vacuum cleaner. The bottom
column bolts can be removed and the column lifted clear although complete removal of the
column is not always necessary.
NOTE : DESICCANT IS NOT REUSEABLE AND MUST BE DISCARDED.
A2.2 DESICCANT REPLACEMENT
Ensure the columns are free from dust, fit new lower column pads and check lower gasket is in
good condition. Refilling can now take place. In order to maintain dryer performance, the
columns must be refilled using a snowstorm filling device which will achieve maximum
packing density. The best results are obtained by using a smooth continuous operation.
A2.3 GENERAL
Each extrusion consists of 2 chambers filled with desiccant material. The manufacturer
suggests a performance life of 10,000 - 30,000 hours, many factors can influence this nominal
figure which should only be used as a guide. Accurate dewpoint monitoring with a hygrometer
is the only true indication of the desiccant material contition. (Consult the manufacturer).
