We had Keith from Saati in our shop a couple of months ago, and was really pitching hard on switching over to the table reclaim system.
We tried it for a couple of weeks before switching back to the dip tank. Our current space just wasn't built out for the table system. But now we are building a new reclaim room, and i'm wondering if there really is a benefit to do a table reclaim, versus the dip tank reclaim.
anyone have any experience they could share?

Can you post a video of the process?

Check with Greg from Minds Eye.
He uses diptank and the table.

A handful of people like it over the dip tank. I tried it here in batches of 4-8 screens, buckets of chems and sprayed. I have an enormous reclaim sink so I stacked on one side and pressure washed on the other. It was definitely faster than doing one screen at a time with scrubbing, but way slower and took a lot more labor than a dip tank (easiway supra takes off the ink and the emulsion in one, then degreased and dehazed). Felt like a lot of wasted chems too.
I currently dip tank all my screens as a batch (usually 30-50 screens at a time, which takes about 30-45 seconds a screen (6 in the tank at a time, one draining while one is pressure washed, and cycled with one screen to the draining rack, another is added to the tank, then pressure washed, repeat). Then I dehaze with 701 in batches of 6, where I scrub on the chem on all 6 as a stack, then pressure wash and soft rinse one at a time, then another stack of 6. This takes another minute or so a screen. Usually for 50 screens I am done with the whole process in a little under 2 hours and not even remotely tired from a bunch of unnecessary scrubbing. I also have a shitty pressure washer compared to the guy in the video, so a lot of the time is just me having to do narrower bands of emulsion.

Table reclaim uses way to much water for my liking.
Dip tanks reduce water and chemical usage which equals money saved.

The first link posted by Mimosatexas is at Kitson's also, I believe. At least I looks familiar and one of the screens (minutes 2:35-2:55) contains a "Mind's Eye" logo in the stencil. https://www.youtube.com/watch?v=OP58rfOUuTA (https://www.youtube.com/watch?v=OP58rfOUuTA)
I use a diptank, but don't have space to devote to a reclaim table.
And I've never tried Supra, but If I could get it to REALLY work with my inks and emulsions, I'd switch in a second.

I started with Supra, then switched to CCI dip and strip as it worked better and was cheaper.

We clean ink with mineral spirits in a solvent recycler, and old Cinncinati Screen Washer, though I'm familiar with the method he's using. For our dip tank, we hang the corner of the screen that's been in there the longest on a hook that let's it drip back right into the tank; for sure it's saves a lot of chemistry from going down the drain before it's time.

In my new shop I built our reclaim to do either table top method and dip tank method...... We found that going to a true table method was only advantageous if you have 2 or 3 full time guys working that system as with 1 guy we never found an efficient way compared to a dip tank method. Right now we are using a combination of dip tank and table top method similar to what mind's eye is doing..... I will try to take some pics or post a video of our process as it's fairly efficient. Right now I have 1 guy doing all reclaim, coating, degreasing, etc and he averages around 150 per day. But we tried the true table top method and no go for us here

Thanks so much Danny! this is exactly what i needed to know!

150 a day that is really good. Is that a 8 hour or more. Can't say I would want to do that all day.

We only run one shift here 7-3:30 each day. There's a few key factors in our throughout of screens... The main guy doing all reclaim coating etc does not ever de ink or de tape screens. That is done before it gets to him which helps speed up the process. The next key factor is auto coating, he can coat 60 screens in approx 50 minutes from start to finish without fatiguing himself at all. And one last factor that keeps our screens rolling is having developing done in a completely different side of the shop which does not effect reclaim at all. My guy works a good pace but believe me he is never busting a sweat or moving real fast lol just nice and steady

A little off topic, but I want to know the ink the Supra actually breaks down. I have tried Union, QCM, GG, and ICC. I always have to completely remove ink (not just scrape) before I dip for the stencil.

I use it with River City's house brand mostly, but also One Stroke, Excalibur, Triangle, Wilflex, etc.
The key with supra is card off all the ink and do a clearing stroke on press, so no clumps anywhere and no ink filling the stencil. Then pressure wash from the substrate side and the last bit of ink will come off with the emulsion. You will still see a ghost image from the ink, but that is what the 701 is for. Scrub that on both sides and pressure wash. Perfect screens.

I got my Saati shipment today and refilled my dip tank. The dip tank has ER2 and works really well.
I tested the Saati IR 26 and it works really well, according to instructions I dilute it 1:1 with water for ink removal and use the table method for ink removal, works really well. I have a bottle of undiluted IR26 for removing haze.
I have basically copied Greg Kitsons system, if it works well for him it should work well for me. So far so good.

That is still great numbers. Even with out the coating he is doing almost 20 screens an hour. Would love to see your setup.
