Filter Driers?
Why Use Replaceable Core Driers?

Filter driers installed in industrial refrigeration systems almost always use replaceable core driers.

What are replaceable core driers?

Unlike smaller driers, replaceable core driers allow the technician to open the drier shell and replace the core(s) as needed.

The shell is permanently installed.

Why use replaceable core driers?

On larger applications the required shell capacity increases.

These larger shells are not easily removed and reinstalled in the event of system contamination.

With replaceable core driers, the installation process becomes a single event.

When the need arises, simply open the shell and replace the cores.

Another advantage?

The technician can physically inspect the cores as they are replaced.

Knowing what debris and contaminates the core(s) is removing, helps determine potential problems.

I always wipe the interior of the shell with a clean rag.

The color of the oil on the rag tells me the condition of the oil in the compressor.

The presence of metal or metal flakes could indicate compressor wear.

Of course, the number of cores varies with capacity.

Also, the type of cores can be changed to suit the contaminate.

Do you have water in the system?

Install high moisture cores with greater water capture.

Did you have a compressor burnout?

Then you'll want to install burnout cores to help neutralize any acid.

Installing replaceable core driers in the liquid line or suction line makes life much simpler when clean up is required.

After isolating the refrigerant, just pop it open, remove the old cores, install the new, close it up, and off to the next job!
