Heat - Just a plug in heater
I need glycol unit but no funds for it yet. Are there wall units that will go to 40 degrees?
How do I control the temp during fermentation without glycol system?
This must be 57" diameter not "57" raduis" that would be 9.5 foot in diameter or a app 2,000 gallon fermenter each deducting 27" for the conical bottom plus some 200 gallons of head space above.
Look into those free standing deep freeze coolers as well the regular coolers that are made of aluminum covered foam panels like you see in big stores like Costco. They are just giant kits with the refrigeration units mounted on top. I've been involved with the electerical end of these walk-ins. Many of them built when Safeway did their major store remodels back in the late 80's, they would be set at -24*F .
How to cool the internal heat created during fermentation process by air cooling alone I bet you would never get the BTU's generated deep inside the fermenter removed, you'll need a liquid cooling system aka glycol to remove this large amount of heat energy generated. Your electrical utility company will also enjoy your rather large electric bills be it glycol or large AC units. JMO's.
