Feedback on Atlas Copco MD Dryer

Feedback on Atlas Copco MD Dryer

(OP)
My company is looking to purchase more of the Atlas Copco MD Series "Heat of Compression" dryer with any new oil-free air compressors.  We already have a few installed (1 to 3 years old) with mixed results but mostly favorable.  I wanted to get feedback from others experience to address some concerns we had over the design.

1. The drum desiccant life - Is anyone getting 5 to 7 years life?
2. Seals around the drying/regeneration zone divider - Any issues with wet gas mixing with dry gas because of seal failure?
3. Operation with VSD compressors at part load - Are you still able to obtain -30 to -20 C PDP?
