So ive been doing some compressor changes lately and alot of them have been burnouts. I've been installing suction line driers on all these units and only a few have I come back to remove them, Mostly because only a few customers will go for it. On the Sporlan box it says that the suction line drier can be a permanent installation but the compressor paperwork says they are only to be installed for about a week after a burnout, then removed.

Whos right and does it even matter.

Probably depends upon the condition of the system. Nasty burnout or crud in the system, probably should go. We're going back on one tomorrow, tech rep from the supply house sent us the project and said we should yank it. If not a bad system, check the temp & pressure drop over the drier and see if it is plugging up.

I always check the drop on start up and if it increases more than 2 psi after 48 hours I yank it. Customer usually goes for it if I explain ahead of time that it is part of the cleanup. I quote compressor, ll and sl driers explaining that the system has to be assessed after 48 hrs and that as many drier changes as necessary will be billed T & M.

If sporlan says you can keep it in I would do a last pressure drop check and then leave it in if your at @~zero.

I got told by the supplier that you can install an oversized ll drier by at most 2-3 tons over the rated tonnage of the unit, as long as you compensate with extra refrigerant accordingly

They should be removed. I got more then one that have been in for years. Still no PD across them.

Seen more then one that was left in, and in 2 or 3 years, they had 5 plus PSIG PD across them. So flip a quarter, and cross your fingers.

It is up to the acid level, which is tested by the tech. And explain
But most importantly, it is up to customer.
It is boiled down to money.

They should always be removed. It's better for the equiptment in the long run.

In the "old days" we would install a Sporlan drier with a removable cartridge.
We would always run the unit a couple of days and then go back to change the cartridge.

But no one else did it that way and we had to follow suit.

It's exhausting trying to sell a job the right way when "everyone" else said it would work.

If you do the research,you'll see that if the proper proceedures have been followed to "rinse" the burn out acids before you install the suction line dryer,you should leave it in.That is the instructions from Sporlan.
If on the other hand if when you open the system you find "crispies" I have always changed out the suction dryer after 3-4 days or a week.
Non the less Sporlan advises that on modrrate burnouts you use the right dryer and leave it.

Sporlan will tell you one thing and the compressor manufacturer will tell you to remove it. I guess if Sporlan is wrong they owe you a filter.

Well they say you can learn something new every day,and I believe it.Could you point me in a direction to get this copland or whatever bulliten about changing the suction filter.I would love to read it.Thanks for any help.

Don't have anything on hand but was told that in a compressor class years ago by the manu. rep. I don't remember which manu. either sorry. I'm sure somebody here will will come up with it.
