any ever heard of a.....

[rojacman]

.......new tool for techs called a....Molecular Transformator???? or am i the last tech inna trade to see this little gadget??:anyone:

[SandShark]

It's news to me. I've always used ice.

[carmon]

sounds like i do not want one.........

[ch4man]

you'll find it on the shelf next to the piston return spring by the muffler bearings

[DMessitt]

It's made by CPS and is comonly refered to as a super cooler used in reclaiming refrigerant.

[mark beiser]

$139? :LOL:

You can make one for under $1
It won't have a fancy housing, handle or temperature gauge, but will perform 100% the same.

Step 1) Make a coil with some scrap 3/8" copper.
Step 2) Solder/Braze a couple of 1/4" male flare fittings on each end.

I made one years ago, comes in pretty darn handy at times.
Works great with just water, or pick up a bag or two of ice on the way to the job if it a rooftop job, or otherwise doesn't have convenient water access. ;)

Looks like it's got a patent better watch out!:grin2:

I find it fascinating that anyone would actually buy one for anywhere near that price...:confused:

Sound like someone knows somting about moonshine :whistle::grin2:

[coolperfect]

Well I must say this,the only moving part is the gauge.That would most likely make that thing ,the only thing,that they make that works!

i made 1 probably 15 years ago, didn't think of a fancy name for it though....:gah:

makes a HUGE difference on a hot day.

[itsiceman]

So does the new cps recovery unit need this super cooler to work in the real world since it doesn't have any built in cooling?

[gasguy]

.......new tool for techs called a....Molecular Transformator????

Yup, sits right next to my flux capacitor. :D

[catmanacman]

I just cool the tank with a water hose although its messy and a pita

[matt1124]

I saw a homemade one in another thread. I thought it was called a worm or something like that.

[boat racer]

I made one a few years back and posted info here on HVAC-talk.

5 gallon plastic bucket, 50 ft of 1/4" tubing with flare nuts and valves on the ends.

Just today I considered it can also be used to liquid charge by boiling the refrigerant in the tubing bathed in water.

I picked up the "Molecular Transformer" tool and looked at it ... no patent claims ... its 100% based on public domain ideas.


Take my idea to use it for charging as well as a recovery booster.

When recovering, remember a water/ice cooled booster condenser can easily let you over fill a recovery bottle ... use a scale and don't goof up.

[crymtide]

Mine is a tub with enough room to give me 2 or 3 inches of space around a 50 lb recovery jug. set up recovery put jug in tub surround jug with ice. Speedy recovery is the result.

I used to do that ... it doesn't compare to a coil of tubing in a bucket. Give it a try.

[matt1124]

So I made one of these today and tried it out. From the unit being recovered, into filter drier, then into the recovery machine. Out of that into the worm, then into the recovery tank. Figured out the hard way that liquid stays in the worm, made sense after I thought about it. How do you guys deal with that? Would it be just as effective before the recovery machine where it would be put in vacuum after the unit is empty?

[boat racer]

You'd have to deal with pumping liquid thru the recovery machine. Not all of them can do liquid.

To clear the liquid, remove the worm from the water ... also try to keep the coils top to bottom so you can run the liquid out the bottom.

I never had your problem, but maybe I just anticipated the liquid and purged it out by going top to bottom and pulling it when I was done.

[mark beiser]

How do you guys deal with that?

Gravity.

[OldSchoolMech]

I was thinking about this the other day while I was recovering 410 and saw how HOT the bottle got. I was wondering with all the speed nazi on hear why no one was talking about cooling the recovery bottle to get faster times. Always talking about Bigger hoses ,removing cores etc This is the first time I have seen a thread on this. I wonder how much faster it makes it happen. I can see this being a big help on 410 recoverys thats for sure.

[boat racer]

Unfortunately the egg shape of the bottle is the hardest shape to cool the contents of ... that's why eggs are that shape.

The length of tubing in ice water is the way to go.

[matt1124]

Ah gravity, duh! Pull it and invert it makes sense! I suppose you need to be connected to the vapor port on the recovery bottle though, right?

[boat racer]

To fill the bottle you can use either port ... vapor or liquid is only in play when taking refrigerant from the bottle.

[matt1124]

what I mean was if I have a long coil like we are talking about and I use gravity to empty it the liquid in the coil would just fill the dip tube and hose as opposed to dropping to the bottom of the bottle and being replaced by vapor in the hose and coil?

[boat racer]

I don't really think you will get that much gravity draining unless you use large diameter tubing.

I have valves on both ends of my worm, if I have to, I can valve it off and move it to the other side of the recovery machine (now that I realize it, that's why I don't have this trouble, I anticipated it and put valves on before I ever started using it).

Mo-lec-u-lar Trans Formator...fancy, useless, made up name for a common every day secondary-heat exchanger.


Like Mark says, us refer guys have been making our own since the early seventies...just drop it in a a bucket of water and you have a water cooled condenser. You could eve use a counter-flow condenser off a water cooled unit to do the same thing. But what is really cool is you can connect a garden hose to it it and really speed up recovery.

[Milk man]

I thought I was cleaver when I made mine. Great minds think a like.

I used 1/4" tubing and coiled it small enough to fit in a scrubs bucket. I have it in a small cooler now. I like to start with ice if possible.

I drizzled soft soldier over the coils to keep the thing together.

Works 100% better than putting drum in an ice or water bath.

:pileon: excellent idea!

Will be adding ball valves and soldering it together. My coworker thought I was crazy and my boss thinks we might get busted for making moonshine but you should have seen the looks on their faces when I had moved 10 lbs of liquid and has sweating hoses and a cold recovery tank running about 125psi! :grin2:

If you just are only looking to cool the tank to bring down the pressure you can use a loop thru the recovery machine to cool it. It's in some instructions :.02:

[boat racer]

Yeah, that woks to cool the bottle, but if you use a coil in an icewaterf bucket, your tank will never be hot to begin with.

My biggest "problem" has been over filling recovery tanks. Use your scale, bcause the recovery will probably be faster than you think.

[matt1124]

It sure is easier to weigh the tank this way. No pulling it out, wiping it off, then still getting your scale wet.

[hvaclover]

none of u guys use a float switch in your recovery tank?

[matt1124]

Never used a float, if all my bottles had them id have no money left for tools

[mark beiser]

It doesn't matter.


I don't really think you will get that much gravity draining unless you use large diameter tubing.

Gravity drainage works the same with a small pipe as a large pipe, the only difference is the volume that can move per unit of time.
Put a container full of liquid at a higher elevation than another container full of liquid, and give it a downhill path to flow.
In short order you won't have any liquid left in the top container.;)

This also works for transferring liquid refrigerant from a smaller tank to a larger tank back at the shop.
connect a hose from the vapor port on the smaller bottle, and to either port on the larger tank, then place the smaller bottle upside down on a shelf above the larger tank, and walk away.
Soon the smaller tank will have only vapor left in it.

[carmon]

never used a float switch.....

[matt1124]

My coil has inlet and outlet on the top so I'd have to at least flip it over. I need to redesign my coil with the output on the bottom going through the side of the bucket then I can just set it on top of the condensor and the bottle on the ground. :D

[hvaclover]

never used a float switch.....

neither have i..was just curious who did since one post was...damn the meds just kicked:gah::cheers:

In 1994 I worked a summer for a company that all of their recovery machines had that annoying cord that plugged into a float switch on the tank.
Most of the time the things shut off to soon, and you had to be VERY careful when cooling the tank with water/ice...
