Insulated shelving unit as a fermentation chamber

Has anyone built a fermentation chamber around a steel shelving unit? The cooling would be provided by a window a/c.

I was thinking of building a lightweight frame around it to provide the insulation. On three sides, there would be vapor-barrier plastic, fiberglass fill, and an outer layer of polystrene. The front would have doors of a similar construction.

A shelf would make better use of my garage space and would provide both a space for fermenting and cellaring bottles.

Thoughts?

 

I would look mor into the "Metro" chrome wire shelving that you see throughout the restaurant industry...now cheaply reproduced through the wonders of big box stores like this...

Just remember the three rules of of a cooler: insulation, air sealing, circulation. The first and second are a lot harder if you are using the a form factor that allows you to access the full width of a shelving unit.

 

Good suggestion. I was thinking of drilling holes through the shelves, but these are of course better in that regard. I was under the mistaken impression that these types of shelves had lower capacity. Glad I looked at your link.

 

The real stuff has some pretty impressive capacity but I am not sure about the big box store clones. How many gallons per foot are we talking (assuming 8# per gallon). I do know the 18" shelving units we used we 500# evenly distributed. for a 4' unit.

 

Typically Metro racks are rated at anywhere from 250-500lbs any any given time like stated, make sure you distribute weight evenly. figure a 5 gallon fermentor weighs 40-45lbs, you should be safe putting 6 or 7 or so on there. It also depends on the clip type. I'm building a ferm chamber out of just wood and polystyrene sheets. It will definitely be strong enough to double as a shelf.

 

I've got some Metro style shelves on order as they were on sale, but out of stock at my local big box.

Given that I could probably fit at most 4 carboys across a shelf, I should be good for weight. I estimate a shelf full of bottles would weigh on the order of 250 lbs, so again, good.

On wood: if I had the wood lying around I would have done that (as I did for the other shelves in my garage and pantry), but I figure that I'd end up spending closing to $50 in wood to build an equally strong shelf. The cost may be flipped for other people.
