Steam Venting Chimney or Steam condensor

Steam Venting Chimney or Steam condensor
During brewing process, it will spent lot of steam for heating the wort, and generate lot of vapor during boiling stage. We should make such vapor to outside or drain. Should we choose steam venting chimney or steam condensor?

Generally, for the brewhouse which under 2000L volume, it usually have steam condensor.

The steam condensor will condensate vapor into water and exhaust to drain.
There are usually 2-3 nozzles sparying city water, the city water will show in fan-shaped to cover big area, and press on vapor, the vapor will become water and flow down; after vapor become condensate water, there will happen vacuum condition, and then fasten vapor goes out.
The condensate water will go to drain, or flow into condensate water tank, here the water will become heat, it will be used in steam generator again.

While, in some large brewery, the steam venting chimney is essential. For large kettle tun, it will occurs much more vapor than small capacity. The steam condensator is not enough to help remove the vapor. It should come with vent chimeny to lead vapor to outside. The three vessel or four vessel brewhouse uaully all come with chimeny.
Inside chimney, there have baffle to adjust the vapor expelling speed.
With venting chimney, it makes whole brewhouse looks much Spectacular.
