Use of same recovery machine for different oils

[Contactor]

Hello everyone

Am thinking of dumping my old R22 machine and just using my newer Pro-set for everything.

Question is - how many people have had a problem using the same machine with different oils?

Oil-less machine shouldn't give any problems I believe.

thanks brian, would you use the same lines for different refrigerants then?

I use "self cleaning" function on my recovery machine and have no problem

If you are removing refrigerants for disposal, and with most modern mixes you would, then it really doesn't matter.

Are you saying you would normally use different lines for each gas when servicing a system?

Interesting Point about charging lines their guys.

Had a discussion whith a newly trained guy last year.

Who said he had been instructed that EVEN purge lines should be purged into virgin reclaim cylinders.
Prior to reuse on another system?

(who is ever brave enough to argue with a trainer when he is wrong?)

I never did find out who the trainer was!
Whatever happened to resonably practical ?

I carry two sets of fridge kit, to prevent mineral oils contaminating polyol esther (& vice versa).

With oilless recovery units you dont have a problem
probably a good idea to keep lines for mineral and esther oils seperate.
Not always practical of course !

Presumably even an oil free recovery unit would be contaminated by traces of oil carried with the refrigerant, which would then mean that it can't be used for the other oil type?

Ditto lines, tools etc.....

As said before, if you are not keeping the refrigerant taken out of the system then it doesn't matter.

There would be a minimum trace of oil left in the machine I think anyway. But you could always purge it first with the gas that you want to recover.
