Dear all,
We are using a desiccant rotor for drying our compressed air. This rotor is build up of glass fibre paper, impregnated silica gel to adsorb moisture. The silica gel itself also acts as a binder to hold the glass fibres together.
After some time, we see that this rotor becomes soft and brittle. The rotor operates in conditions with temperatures up to 150°C during the regeneration phase and around 30°C during the adsorption phase.
Has anyone experienced similar reactions?
Has anyone an explanation for this phenomenon? Some already mentioned that a hydrothermal proces occured, but does this proces affect the silicagel or the glass fibre?
Many thanks in advance!
Best regards,
Max
