ZoomLock, RLS, Streamline

[mobiledynamics]

Not in the HVAC trades as all, but calling all those who are....

Just curious. For the 3 systems out there, Zoomlock Max, RLS and Streamline.
I noticed Milwaukee has released jaws for the existing press tool for the Zoomlock and Streamline. They did not come out with for RLS, which is the original zoomlock.....and a pic of the Streamline shows 2 seals on each end of the fitting.

Just curious is one connector superior over another or whatever you can get @ the supply house

There all major players if you can get jaws for your tool and supply house carries that brand use it. Tubing prep is more important than the brand.

Yes, prep is key. I posted a post or 2 on ProPress.

I found it interesting at that time that Viega was the only Manufacturer. who appeared to be also have -lube- on their O Rings on their fittings.
Fast forward to my last batch of connectors....which I suppose its either cost savings, but the Viega ProPress fittings are basically like everybody else now and it's -dry-. Not sure if it mattered or not at the end of the day.....but I viewed the lube as a ++ to mitigate dry rot or at least delay it.

They don't use rubber. Rubber couldn't put up all the different types refrigeration oil, pressure and size of the molecules from leaking through the gaskets.

These bad boys use rubber.

Not used for refrigerant.

They sure are. I've got a hair under 3000 of them installed on my HVAC at work.

These are refrigerant lines.

Gruvlok uses EDPM for a standard gasket.
I'm very familiar with both companies and their gaskets for hot and chilled water. Remember when groove pipe first came out the grooves weren't rolled. Called a supply house with measurements and they cut the grooves into the pipe.

Post the brand and part number of those coupling for refrigerate. Retire 13 years never have seen them.

I posted a picture in post #6. Victaulic is the brand.

We use models 607 and 644. They have several different gasket types based on the application. Ours are used with R-134a.

Here's a cut sheet for their different gasket types. I trimmed out just the listed refrigerants.

Never dealt with 113 or 114

The only refrigerant listed that might be viable is 134. 11 and 123 worked with with Trane,York and Carrier centrifugals. All these refrigerant are obsolete. R 11 used to put it in a hudson sprayer to degrease motors and anything filthy. Before reclaiming became law.

As for as the original Zoomlock (before max came out) we had a couple sets of jaws for the original zoomlock that worked in the milawkee propress guns. When Max came out the Sporlan rep swapped all our jaws for the new zoomlock max. We had a class on Zoomlock and the Zoomlock was not capatable with r-22 becuase of the orings thay used.

Propress fittings and Jaws are not the same as Zoomlock press fittings.

Looked at the gasket selection didn't see any of the newer lower pressure refrigerate listed but it might be a old list on line. What type of unit do you have pictured?

A large split-system. We've got 34 of them to cool a data hall. R-410A cools the R-134a, which cools the room.

The 134 operates on thermosiphon, the 410 has Copeland scrolls. All the 410 joints are brazed.

That list is slightly outdated, but I'm not sure if they work with any A2L's.

Like I said, all 2,992 of our fittings are on the R134a side.

Only time I've seen a cascade system was low temp freezer for Mallinckrodt chemical only thing was R12 unit was to cool low temp. That was 30 years ago. Was there working on a 30 ton Dunham & Bush screw hermetic compressor chiller.

It's a really efficient, and frankly impressive system for the most part.

Unit runs completely in passive up to 65°F ambient to cool the data hall. Each unit is rated at 400kW of cooling, or about 114 tons.

Company worked for did a Mastercard in st. louis was like a building in a building where all the cooling equipment was located in the outer building so no service people have to be in the data area.
With rigid couplings can see how the copper would break from expansion and vibration. Did you go back with vibration /expansion absorbers? I've also used angle iron strapped to straight copper to change the frequency/ harmonics of the pulse to help.

Hasn't posed a problem yet. We have the very first units sold in the field. About 5 years old now on the first batch. Maybe time will tell.
