I use three tanks for bottling different kinds of honey.
A 300lb Maxant and a 300lb Dadant water jacketed bottling tank and a 150lb Dadant Liquidator (that I only use as a bottling tank). All bought over the years from defeated beekeepers.
I detest Maxant's 1 drip bottling valve, it only works when you're pressing the handle down.
The Maxant tanks drain is on the side, to completely drain the honey you have to tip the tank.
Maxant sells a pail perch compatible with their tank.
My Dadant tank has a ball valve, freeing my hands allowing me time to screw the lid on one jar as another is filling.
Dadant tank's drain is "U" shaped and flush with the bottom, allowing the tank to completely drain.
Dadant's inner tank sticks up 2.25" above the water jacket.
They don't sell a pail perch that fits their tank..., I made my own.
Dadant's Liquidator is a single walled tank with a bottom mounted, ball valve.
I heat using an electric heat cable (from Kelley's) wrapped around the tank.
After 20+ years of use, I tore the weld on the ball valve's nipple and had to have it welded.
There are pail perches for this tank.
I mostly use the Dadant tanks..., because of the ball valves.
One day I'll replace the 1 drip valve with a ball valve..., until then I'll curse it.
