    Fermentation chamber


    Hi

    I am thinking of building a fermenter chamber for cooling and heating.
    It will cater for 2 fermenters and about 100 440ml / 60 750ml bottles. Approx dimensions (1m X 0.7m X 0.7m)
    Max cost should be no more than R2000.
    Thinking of using light bulbs for heating or some type of heater / heating pad ?.
    For cooling a thermoelectric peltier refrigeration cooling kit from communica (http://www.communica.co.za/Catalog/Details/P3265877730). However this unit uses 12V. This being the case it would be simpler to have everything working from 12V.
    I see the STC-1000 temperature controller is a 220V unit.
    Anyone know of a 12V temperature controller that can control cooling and heating ?.
    Any other generel input will be welcome.

    And old fridge or chest freezer with a controller will work better. Peltier modules are quite "meh", and more built for stuff like in-car cooler boxes and not really long-term use like you're planning.

    +1 ... That thermoelectric peltier kit from communica is good enough to cool a box made for a case of beers

    Had a mini-fridge with one of those setups ... struggled to keep beer cold ... i'd say it made more for wine-coolers

    Hi Beerholic,
    My cabinet is about 500x600x700 which I use for fermentation of one 25l bucket at a time. I bolted the Peltier 'lid' from a 50w Thermo cooler box to the side of the cabinet. It does the job but in the peak for summer the unit runs almost continuously. I think the communica 60w unit would struggle with your size, especially loading in 100 warm bottles. My lamp setup however, works a charm. I actually had to hunt down a lowest possible wattage bulb as the temps would spike otherwise

    Oh, and STC1000 is available in 12v. Most HBS just keep the 220v tho. Try bidorbuy as a starting point, but those are usually imported at your risk, albeit often cheaper.

    Thanks

    I agree after fiurther serearch thye peltier will not work for may size. Back to drawing board.
    The reason for a fermentation chamber and not fredge is optimazation of space. I will only be doing ales so do not really need temps below 20 celcius.
