Does anybody have experience with the Mastercool 69100 recovery machine? The ad says it'll filter,clean and remove moisture and debris. It doesn't say that the freon can be put back into the system after the repair. Also can this machine be adapted for use with R12? If nobody has an answer, where can I check?

I emailed mastercool and they said that it was not recycled enough to reuse. Email below (removed names).



Hello,

It does not say recycle on the label it states cleanse the refrigerant. If you were to put back into the system you would run in to high and low pressures and would not get a good cool air out of your system. It does clean somewhat so when you go to recycle it is not so contaminated and cost less for you.

I am surprised you all will label is recycle. Will the recoverymate clean it enough to go back into the system?

With the 69100, does it cleanse the refrigerant enough that it can be reused? For example, can use recover r134 from a car into the supplied tank, then charge the car back up with the refrigerant that is in the supplied tank?

Thanks Jeeper. I've been told by a few technicians that it might be fine to evac a system and change a component and reservice with the origional charge as long as contamination was not suspected. I wonder what the tech was referring to with the high and low pressures problems and less than normal cooling. It does say in the ad that the 69100 removes moisture etc.

If you get air in the recovery tank, it can get into your system when you reuse the refrigerant and cause poor performance. Start with a good vacuum in the recovery tank and be careful to evacuate / purge the machine and all hoses when connecting.

The EPA says it's OK to put your own refrigerant into a tank and reuse it. If you're working on other people's cars you can't transfer refrigerant to a different owner without legally recycling it first.

Thanks MK 378, that all makes sense and I understand about the air and purging. I'm only working on my own vehicles. I've been working on cars for over 40 years but just now getting into A/C. Since all my vehicle are 89 - 91, its seems this is the year that all the R12 systems decide to retire. I'm trying to get the best equipment I can before I tear into them. This MasterCool 69100 looked good in the write up and I wanted to hear from people who have used it as a recycler. Also I was wondering what restricts it to R134A. If you adapted the connections and used a different tank, wouldn't that make it possible for use with R12? I suppose the gauge set is only set up for 134. I do have a manifold with both 12 and 134 displays.

The 69000 is the plain machine it is suitable for all refrigerants. The 69100 appears to be a kit of a 69000 machine with a cylinder and and a bunch of hoses and fittings all acme type for R-134a systems, that is why it says 134a.

For home use you should look for a 15 lb recovery cylinder as there is less dead space inside. The first time you recover you have to fill up the vapor space in the cylinder and you can never get that refrigerant back into your car.

That unit is a recovery machine; not a recycler. there is a huge difference between recovery and recycling.

I hate starting new threads, and this answered one of my questions, so I will just add the rest of them here. First, does anyone have one of these 69000/69100 units? Do you like it and would your recommend it? When using this machine, has anyone ever set the recovery tank on a scale to measure what was in the system and how accurate do you think this measurement is or would be? It feels like winter here today, but I am trying to get a trailer setup to do mobile repairs (out of the shop) and am looking for something suitable for this. I don't want to invest thousands into a R/R machine at this time if it can be avoided, but do still want a quality setup out of the shop. Thanks.

I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!

I have a 69100 but since this is the only machine I ever used, I can't answer if it's good or bad. One issue I had was after using it was the low side manifold hose had oil in it instead of the machine itself which is supposed to catch it. I think I posted that question here and was told to contact MasterCool. Their answer which I'm not sure is correct was that it was excess oil. Since this wasn't a vehicle but a dehumidifier using 1lb of R410A, I don't know how oil it holds but probably not that much! Believe it or not but even the service techs at the manufacturer could tell me how much or what type of POE oil it used! They said whatever comes in the compressor, they use and have never have added to it.

BTW- I use a vacuum pump connect in my hook up when using the machine along the lines as the instructions for the MC 69500 unit. HVAC techs use this method and there is less chance of getting air into your recovery tank if they intend to reuse the refrigerant.
