i am having trouble with this setup

Explain your problem.

im just trying to use this setup to void fluids

Fluids cannot be directly voided without a mod; pumps which are not connected do nothing. Items can be Recycler’ed into nothingness (or thrown overboard into the Void of Space / fiery Lava).

You will want to find a Recipe which consumes the excess fluid, and then throw the resulting Item away.

Good Luck!

I don't see a reason to void any fluid. Your problem usually doesn't come up on a Aquilo base. For every fluid, there is some recipe that consumes this fluid. The recipes are balanced in a way they will consume more than what is being produced.

About fluoroketone (cold) and fluoroketone (hot): these fluids are used in a production cycle. The hot variant is being created first. It needs to be converted to cold, then it is used by some production recipe which will consume a part of it and output a little bit of the hot variant as byproduct. Merge the hot byproduct with the other pipes also carrying the hot variant. Then convert the hot variant again to the cold variant, then the cycle starts again.

Your issue is probably that your cold fluoroketone production stalls because cold fluoroketone storage is full, and because the hot fluoroketone isn't being removed any more, any machines producing hot fluoroketone stall as well.

The solution to this is not to void cold fluoroketone but instead stop producing hot fluoroketone. Add a storage tank for hot fluoroketone and connect a circuit from it to the cryogenic plant that's producing hot fluoroketone. As activation condition in the cryogenic plant set "fluoroketone (hot) < 15000". This way production stops if more than 15000 hot fluoroketone accumulated, so there is still storage space for any other source of hot fluoroketone as byproduct. As soon as the level lowers below 15000, it's being produced again, so it will not run empty.

Without exercising any judgment about whether this is a good idea, if you want to void fluids, here are a couple of ways.

1. If the fluid can be barreled, you can automate voiding it by:

• Barreling it
• Shipping the barrels to Vulcanus
• Having an inserter throw the barrels into the lava

Fluoroketone can be barreled, so you can do this with it if you want to.

2. If you don't mind doing it by hand or having construction bots do it, you can simply fill a storage tank, then deconstruct it. The contained fluids disappear.

3. As I think someone else pointed out, you can also automate this by barreling the fluids and sending them to a recycler. The advantage over method #1 is (a) you don't have to ship the barrels anywhere interplanetary, and (b) you get at least some barrels back, whereas dumping the barrels in the lava consumes the barrels as well as the fluid.

4. As another person points out, if you have the barrels on a space platform, you can have an inserter just toss them off into space; you don't need to send them all the way to Vulcanus to throw them into lava.

I do exercise a judgment here, sorry, but if you have the barrel already in space ,you can just dump it into the void of space, no need to ship it to Vulcanus , that does consume the barrel and is a waste of rocket compared to recycling them, or attempting to not be in a situation where that feel necessary, which would be my advice here, reading the amount of fluoroketone from a tank, and using that value to activate or not the machine that produce the fluoroketone to make sure it never get stuck or full.

The problem with your setup is the pipe above the pump. You must pump directly into the cryo plant for fluid voiding. Otherwise the pipe will buffer the factory-ejected fluid instead.

Thanks, forgot about that option. Added.

When looking at the picture one more time, i noticed the pump tickbox for "enable/disable" isn't ticked in one of the picture , only the condition is set maybe that's what causes the pump to behave unexpectedly ?
