FLOTit Floating Dip Tube
Floating dip tubes are a sizzling commodity within the homebrewing world these days. Many individuals are ditching their mounted metal tubes and changing them with a size of silicone tubing hooked up to a stainless ball float. If you happen to’ve been dwelling beneath a rock and don’t know the purpose of the floating dip tube, it’s fairly easy. It floats on high of your beer in order that as you draw out beer, you get clear beer from the highest whereas every little thing else precipitates out and makes its solution to the underside.

FLOTit is a product made by Trong Nguyen- hand assembled at his residence, and bought by way of eBay. He’s gone by way of iterations of enhancements on his float design, however even his first design was one thing aside from the ever present silver ball design. The difficulty with the ball design he was making an attempt to beat was when the ball floats, the inlet tube dangles down under (more often than not) and hits the yeast cake whereas there’s nonetheless a layer of beer left on high.
The preliminary design (FLOTit 1.0) had a cylindrical float, with the inlet tube mounted to the middle of the float. To supply a layer of safety from transferring sediment, the top of the tube is fitted with a mesh display. The FLOTit 2.0 nonetheless has a cylindrical float, however the gap is offset the place the tube is hooked up. The offset design helps maintain the top submerged within the beer, particularly because the beer degree will get low.
The FLOTit 2.0 additionally incorporates an enchancment on the meshed finish. It has a Double Filter Inlet (DFI), which is 2-3” lengthy meshed cylinder packaged inside one other meshed cylinder. The outer cylinder has a 500 micron mesh, and the interior is a 300 micron mesh. The DFI is considerably modular in that it may be used with the FLOTit cylinder floats, or you possibly can add it to your dip tube with the floating ball, should you needed.
The fundamental FLOTit equipment comes with the float, a size of silicone tubing, and quick steel dip tube to go within the keg (beneath the ball submit). The diameter of this quick tube and silicone tubing are sufficiently small to suit up by way of the liquid out gap on the keg. This lets you connect the silicone tubing from outdoors the keg, the place you could have simpler hand entry. There may be additionally one other equipment possibility that provides in a brief fuel dip tube if you wish to swap it out for a barely shorter size. With the shorter fuel tube, it makes for a simple solution to pour out any residual sanitizer you might need left in your keg after purging (simply flip the keg the wrong way up with a fuel ball lock hooked up to the fuel submit). These particular tubes are a molded silicone boot, with a steel washer bonded to it. This makes them extra compliant to any floor imperfections on the keg interface, but it surely additionally means you want to make sure to not overtighten. The instructions say hand tight then 1/4 – 1/2 flip additional with a wrench.

I exploit a floating dip tube in a single spot in my brewing course of at present, and that’s in a chilly crash keg. After fermentation is completed, I switch the beer into an oxygen-purged chilly crash keg, add some CO2 head stress, then stick it within the fridge to chilly crash and get yeast to drop out. The floating ball lock on this association is nice, as I pull beer off from the highest after a pair days of chilly crash, into my serving keg. With the chilly crash dropping out most of my sediment, I maintain my serving kegs easy with the usual/inflexible dip tube. So I did some trials with each the FLOTit 1.0 and a pair of.0 on this chilly crash keg.
There may be an error state with the ball float design that I needed to see if the FLOTit might resolve. With the ball float, sometimes the dangling pickup tube can get itself wedged such that it sits on the high degree of the beer and sucks in principally CO2. After biking by way of a number of batches, I can say the FLOTit resolved this situation. Specifically, with FLOTit 2.0’s off-center attachment gap on the float, it created a slight tilt to the float, making certain the pickup tube finish was all the time sitting just under the liquid degree.
Measuring the beer on the finish when it began spitting foam, I had 9-10 ounces left within the keg. This was excellent for my chilly crash keg, as a result of by the point I bought to that degree, I used to be beginning to get into the yeast sediment anyway. My chilly crash keg is a 6-gallon Torpedo keg, so the underside is domed upward contained in the keg. This geometry makes is hard for floating dip tubes to get really the final drop, because the float can backside out on the domed up backside. I didn’t strive it in my conventional cornys, however with these being domed downward, I count on I might have even much less beer left on the finish.
I did discover that the FLOTit, like its floating ball brothers, is delicate to the appropriate size of silicone tubing. I initially had the tubing too lengthy, and because it bought towards the underside, the silicone tubing hit the underside earlier than the float, and the tubing ended up making a ‘J’ form, as a substitute of an ‘L’. With the ‘J’ form, the tip curved up and caught up above the beer degree. So I trimmed it again and made positive the float would sit on the backside of the keg on the alternative facet (under the fuel in submit), and never so lengthy that the tubing was laying on the underside.
One thing to remember with the DFI is the place in your course of you’re utilizing the floating dip tube. In my chilly crash keg, I push beer in from the fermentor by way of the liquid out line so I can fill the keg from the underside. However meaning any dry hop residue/and so on. from the fermentor has to cross by way of the mesh display earlier than it might fill the keg. I rapidly discovered that doesn’t work when transferring a dry hopped beer, as a result of it plugged early within the switch part. Utilizing the a lot bigger display opening with the non-DFI finish labored high quality, so I caught with that. If you happen to’re utilizing it in a pressurized fermentor, the place the floating dip tube is just used to tug beer out on the finish of fermentation, the double-layer display safety can be sequenced correctly. However you’d additionally want to make sure you didn’t have floating dry hops (chilly crash first) or you can plug the screens on the switch out.
Conclusions
General, FLOTit 2.0 labored very nicely for me. It solved the one downside I had with the floating ball dip tubes, which allowed me to completely make the most of all the benefits a floating dip tube can present. Priced at about the identical price because the ball floating dip tubes, it supplies an excellent various. And should you use it inside a pressurized fermentor, the extra mesh screening is perhaps one thing that uniquely suits your wants.
