Do you connect external reactor before or after chiller ?

Don't mean to start a discussion on solubility of gases in lower temperature but just curious as to why you rig your external reactor after or before your chiller.

what is the recommended? is it after chiller?

[eriond]

Some questions I pondered before rigging..maybe u have other interesting questions too.

Before chiller - CO2 may not dissolve that well at higher temp and will the CO2 affect the chiller since it is acidic ? Maybe a built up of gas in the chiller chamer?

After chiller - Since it is external reactor, won't the water start warming up even before going into tank ? Chilled CO2 dissolved water in an external reactor, will it tend to invite algae ?

There was a discussion about solubility of CO2 in different temperatures. It also covered some of the questions you brought up above.

Thanks Vinz, I did see that thread and that is why I start this thread. I m just curious as to how many are rigging it before though I know most would probably rig it after the chiller, hence the poll.

no one connecting the external reactor before the chiller ? would like to hear your feedback if u have done so.

the difference may not be significant.
chiller can handle the weak acidic condition resulting from co2 injection so it doesn't matter whether co2 is injected before or after the chiller. and chiller does not have any chambers, just one tube running through the cooling medium.
the amount of heat being 'soaked' by a reactor depends largely on the surrounding ambient condition. if you suspect that the heat soak is significant, wrap the reactor with a towel. this will minimize the heat soak. and with light being cut-off, there will be no algae in the reactor.

I dun there will be much difference in terms of the co2 solubility. Its rather the flow rate requirements of the chiller than anything else. putting it befor the chiller will slow it down....
