Kaeser membrane dryer

Hi every one

In my company we are using the below types of Kaeser air compressors:
ADS 32 S
DSD 171 S
BSD 72 S

All of them have same problem; membrane dryer purge air increased (3 months after replacement) leads to high DP across the dryer line.

And these dryer elements supposed to be changed every 3 years.

So can anybody give me a solution for this problem?

Thanks and regards

Membrane dryer failure

If you go to the Kaeser site you can download information on their membrane dryers.

All of the membrane dryer models on the Kaeser site I found have an upper inlet temperature of 100 degrees F. That is 38 degrees C.

I suspect your inlet temps are too high at 50 degrees C, contributing to the membrane failure.

So, what's between the pumps and these dryers?

another dryer? filters? or just pipe?

If you don't have filters, you probably need to add some.

What's the temperature at the inlet to the membrane dryer stack? What is the Pressure there too?
