=== Optional: BZ production ===

[[File:Hfr-delta-example-bz-formation.png|400px|thumb|right|Configuring the lower supplementary mixing chamber on Delta Station for BZ production.]]

Delta comes with additional mixing chambers. The south mixing chamber is very attractive for BZ production provided nobody else wants to use it, and it requires very little setup. Open floor tiles come with 2500L capacity each, and so is significantly more efficient than trying to perform the same reaction in the port area with T1 canisters, which have a capacity of 1000L each. Even with T2 canisters, which have a capacity of 3000L each, this nine-space (effectively ten-space, if you make the input pipenet large enough, as shown in the illustration) area will easily outproduce even six T2 canisters monopolizing the ports area. Six T3 canisters in the ports area is barely more efficient, providing 30kL of volume instead of 25kL, but maintaining throughput while taking advantage of the lower potential pressure per 5000L reaction area is much harder than running parallel in the supplementary mixing chamber, along with taking much longer to build and losing easy access to the cooling required to maintain sufficient mass at low pressure.

Replace the inbound connector with a Gas Mixer, and set it to pump 60% Node 1 (plasma) and 40% Node 2 (N2O), as in the illustration. The rate of consumption is closer to 66:34, but being bounded by N2O will cause much of the produced BZ to become oxygen instead, which is an important condition to avoid. The ratio can be changed closer to consumption values once filled with the safer, N2O-heavier buffer, if desired. Setting the output pressure to 40kPa ensures a good set-once rate of production and throughput. You can lower this once the chamber is filled if you like. Space cooling (to about 27K) lets you reach required mass values while being tolerant of proportion divergence even at 5kPa (holding a mass of 54.4 moles in a 2500L volume, where BZ formation requires 10 moles each of plasma and N2O), though this will take longer to replace input, so setting a target pressure below 15kPa or at least 10kPa is not recommended - the actual pressure will tend to be lower than this, anyway.

Grab a hardsuit, drop a holofan projection between the airlocks to stop station air leaking, and press the vent control button to open up the chamber to space. Replace the vent with a pipe into a manifold, add a Passive Vent to the middle of the chamber, and keep extending the pipe network with a heat exchange junction to space. Drop down a few 4-way Heat Exchanger manifolds. 4-way manifolds add 140L, and a straight pipe adds 70L, so using 4-way manifolds adds just as much volume as clever overlapping setups, while being much simpler to build. A few HE 4-way manifolds is enough to provide minimal cooling. Extending to 15 HE 4-way manifolds brings the network volume to 2625L, which means that if the BZ formation reaction is occurring in the open floors, it will also be occurring in the pipe network, functionally adding a tenth open floor space for the formation reaction to occur in.
