    Question Charcoal or Carbon filter for steam stack aromas ?

    We are looking to put a 7bbl brewery in a location that has apartments on the floors above our space. The landlord is asking that we place a charcoal or carbon filter on the steam stack from the boil kettle to reduce the aromas from the beer production. The landlord is also wanted a negative pressure to be maintained within the space to keep any aromas within the space. Has anyone else encountered something like this?

    I should make a note that the vent run would be approximately 100' (40' through the building, then 60' up through the roof), and would need to be powered by a roof mounted fan.

    I would look into a vapour condensers for your stack. No vent needed if you use one. I know Specific Mechanical has made them for some brewers. Basically your stack runs into a small tanks with water misters in it that condense the steam. the hot water can then use for other purposes or dumped. Cheers

    Vapour Condenser

    We agree, a vapour condenser would offer a simple and cost effective solution that would address your needs.

    We fabricate a condenser that has a unique design relative to many of the other solutions that are offered in the US market today.

    Most notably:
    • Our solution works with the laws of thermodynamics to reduce the amount of cooling water required (all else equal) to knock out steam and odors. This translates into savings.
    • The design emphasizes the need to prevent undesirables from making their way back into the kettle.
    • Our customers achieve an excellent boil off.

    Please let me know if you would like more information about our solution.
