The pump has induction motor so the speed will vary depending on frequenzy. It will work on both 50 and 60 Hz and there is probably even label on the motor telling the performance difference. https://www.kaixinpump.com/product/mp_6r_magnetic_drive_pump

Proportional motor valve would make it possible to adjust flow with voltage. For example Motorized Valves – BruControl

I connected 40 € vdf to 65 W magnetically coupled induction pump and it seems to work ok. Long term experience is yet to come.

New chiller Coolossus - Passivated Stainless Steel Counter Flow Chiller Heat Exchanger Not happy with the placement of that one weld.

I think the biggest problem is poor heat transfer between air and glycol. I would add a heat exchanger like the ones used with pc water cooling. That and a fan would make glycol a lot colder.

Silver soldering could work. I used that to patch small hole in my friend's Grainmaster.

Isn't the flange size defining bent radius? I have 1,5" flange 90 degree elbows with 3/4", 1" and 1,5" pipe and they all have flanges at same distance.

At least current (new?) model has description "The Conical Fermenter is constructed with a double walled skin filled with a thick layer of polyurethane foam for insulation." I think the unique valve is partly result of insulation. I have also seen insulation jacket for grainfather conical...

I thinks it's possible because grainfather conicals are well insulated.

I think it would work only if water is running inside of the copper coil and the coil is quite long. That cooling water could be part of closed loop system consisting a pump and radiator with fan to loose the heat to surrounding air. A lot more complicated system compared to this topic's condenser.

Does your cleaning cycle clean up all hoses and threaded fittings or is it necessary to clean them manually sometimes?

Maybe I could circulate hot worth through all valves, I have to think about that. In general I want a system which that can be cleaned without taking anything apart. Pinch valves looks to be easier to keep clean. Another ideas why I'm planning on making pinch valves is size and throttling. Motor...

If I make chamfer in the head of the pipe and use same ID pipe and hose, then would it be as good as hose barb fitting? In the picture there is 1 mm difference between IDs.

I am making a fully automated mash and boil kettle. There will be a lot of valves and hoses and I would like to clean them in place. My plan is to use connections without threads, like sanitary connectors or just putting silicone hose over a pipe like in the picture. As valves I'm thinking DIY...
