Three two one go takes in the bottom: weighed 40 pounds hits zero, we're done hey this. Video is a recovery speed race between the nav again, our DD digital recovery machine and one of the kind of industry go twos for a really long time that we've had even at Kalos the Abbey on g5 twin. So in this video we want to kind of show head-to-head how they operate, but then also just give you some quick tips on proper recovery practices. The first thing that I don't think Bert mentions in this video that I want to mention here is that pulling cores out while recovering is one of the best possible things you can do while recovering and also keep in mind, using a good high-capacity liquid line.
Dryer flare, dryer in place is also a really good practice when you're recovering here he doesn't do it because he wants to everything to be his head-to-head as possible and remove as many variables as possible. Alright, here's Bert hey guys. This is Bert, I'm HVAC school and today we're doing a little project me and a stasis. We are going to be testing the new Nevada, recovering machine.
It's a digital recovery machine, we're going to be testing it against probably the most common recovering machine. You see in the field the g5 twin. This is our setup for the race. We have it each of them coming in from our full tanks on the vapor, then each one has a field.
Theis probe hooked up the show the tanks pressure and you don't actually need that on the digital, but we will for the a beyond so just to make sure everything straight will show that the field piece rose and then right here. I hooked up these gauges to our tanks that we're actually recovering into so we're covering in two here. We can see what kind of pressure under recovery high pressure that these tanks are so next thing most important right here. We have both of our skills zero out.
So, let's go ahead, clear, clear all right: let's put the tanks on our scale. These tanks have them back in. So, as we previously show, both both things from the bottom weigh exactly forty pounds and have the back saying to wait. They're both holding 11 point something like eleven point: seven, so we got 28 28 come show on both tanks weigh the same and that's their tier.
Twenty eight point three so already saw me, bleed the lines, so I blood the lines and then we're gon na open everything and turn it on. At the exact same time, these things are both in a vacuum. So if I open them right now, they'll pull through on their own without the recovery machine. What I'm gon na do is turn them on we're gon na turn, both on saxing time and then we're going to open the valve so they're both running when they can actually dump into the tank.
At the same time, the race is about to start three two one go takes in the bottom: wait: 40 pounds tear way, fluffy point something that is in there. Cop will be down at 40 pounds and you're recovering you're, going to be recovering both of our fields. When that hits zero, we're done. Okay, that's the end of the race, we're gon na see who hit zero. First. That's that that's the goal! This in case we're not clear. It's a race Reza's! Now back Maxwell, it's snow! It really hits Florida snow sometime. I just left running such a low temperature psi fantastic.
There we go, we play on the top, so finish yourself, third cycle. Turning some clothes other way purge cycle just gets all the refrigerant. It came out of here as much as possible into our tank, which is thirty six eleven and over here we have 36 one out. Ok, well, the race wasn't quite as speedy as it might have liked.
That's the race for us it's over just over 13 minutes. We hit zero psi on our nav ACK and then nine minutes later. The appian hit zero psi from its tank and we were able, with the purge from the nav act, to recover 36 and 11 ounces and the nav ik when we stopped it at zero. Psi was able to wreak a recover 36 pounds exactly Zeus, any closing thoughts.
How'd, you feel about this. I want you want it, he's really hoping that he will get this just because of those video. No, I was. I was really good it's a little bit bigger, but which is really great.
Has it not good features, makes it a lot easier to recover, then there's a lot faster is also a lot more efficient. I hope you guys had fun with this. Maybe you'll learn something throughout the whole process: don't overfill your tanks, 80 % yeah! That's right! If you need a little cheap math like we use, there's a great article on recovery, tanks written by brand or HVAC school, alright. So the end result here, just in summary, is that the nav again RDD while they were very head to head when you're in liquid phase and when there was a higher pressure coming into the pump once it started, getting down into lower pressures, which means lower compression Ratio, the larger condenser coil on the NR DD really helped it perform better, and that's why we saw there at the end.
Then again, RDD really got the job done quicker and, in the end, got down to zero psi right about nine minutes faster, which is significant. Hopefully, you found that interesting thanks for watching.
Give me the G5 all day, smaller and lighter, and easy to replace parts. Also refrigerant-isolated crankcase so no problem with A2L refrigerants.
Honestly this sold me on the Appion over the Navac, 10 minutes is nothing for recovering 22lbs at the cost of $250 dollars more and a larger unit (Which takes more space on the truck)
I guess recovery machines don't matter that much then. Service area Barrhaven??
Now try ro recovery liquid 😀 and add to competition JB INDUSTRIES F6-DP 😀
I am getting ready to purchase my scales. I have NAVAC smart pump so am looking at their scales. Also have the Feildpeice Job Link Probes Kit. So I am looking at their SRS3 scale that goes with Job Link. Also like the UEI WRSX scale. Also looking at the CPS cumpute-a-charge with the electronic solenoid valve. Please give me your opinion. Thanks from Tennessee, and God Bless. Thanks for all that Bert and Bryan have taught me.
Great video. I love watching abdominal reading the comments. Getting out of school soon. Switching Over from electrical to hvac Are you in Orleans ?
Appion with 1/2" megaflow hoses might make up for those 9 min. Service area Kanata??
Was both machines new appion looked used?
I’d def dip my toes in the navac pool if they were available at our local parts house that way it be easier for warranty claims. Surprised it isn’t available at johnstone supply.
This video gives the impression that proper recovery is only down to 0 psi. This is not the case. If it were, you could just chill the cylinder until the pressure went down to 0 psi, without ever haven taken a single ounce out. You are required to recover the refrigerant until the pressure STAYS at 0 psi at ambient temperatures. These tanks still had POUNDS of refrigerant left in them. That is not EPA recovery.
Just a few comments sticking up for the G5 Twin. With California putting the brakes on HFCs, and R32 right around the corner. Having a recovery machine that can recover A2L refrigerants is probably going to be important. The G5 Twin is one of a few recovery machines that can recover A2L refrigerants. I have been looking, but haven’t seen any documentation that the NRDD is rated for A2Ls.
Also as a side note. The G5 Twin doesn’t need to purge, it doesn’t allow refrigerant to enter its crankcase, so there’s nothing to purge. Saving nine minutes is cool and all ,but I’m going to stick with my G5 for now.
Which port was the refrigerant leaving the tank from?
Can you do fieldpiece mr 45 vs navac?
Thanks alot … I have a question in cooling and freezing rooms : what is the relation between room tempreture and saturation tempreture for freon in theevaporator coil ??
The navac is nice but it looks large and heavy
Crazy. The Apppion G5 Twin is a beast by recovery standards. We use an old one that still kicks ass but that NRDD looks awefully tempting.
Was the G5 brand new like the Navac? If not this doesn't count. Apples to apples. Still a good video though. Thanks
Bert looks like the druggie Dad who died in Dexter.
Wish the Fieldpiece MR45 was in this test also.
You should consider reshooting, and try only dumping the refrigerant into the vapor port of an inverted tank. The diptube adds a crap ton of resistance to recovery.
The Navac looks like a copy of the MR 45.
Thank sr. Another great video sr
Why are you guys recovering vapor not liquid? Are you in Ottawa ?
I can buy parts for my Appion G5 twin at my local Trane supplier. Can you buy parts for the other?
The screen and the alarms look & sound like the Fieldpiece MR – 45 on the navac
Great video. Thank you for sharing ^_^
Great video. Bert makes life that much better!! BERT BERT
I'd give up 10 minutes to have the smaller machine. Room is everything on a service truck.
Don't eat the yellow snow !! Service area Nepean??
