Title: How to covert a mini fridge into a frementation chamber. DIY
Post by: Frequent Sequence on March 07, 2016, 06:18:05 PM
Hot to convert a mini fridge with ice box into a fermentation chamber

I Got this fridge for free as it's a bit tatty but with a little modification it's a perfect fermentation chamber.
These under-counter mini fridges are often overlooked by brewers as the icebox gets in the way and makes it difficult to fit full size fermentors.
Here is a guide to modifying the icebox section so the chilling plate is flush with the back wall giving you ample room for one full size bucket/carboy.


Any questions feel free to ask.

Cheers.  8)

Cheers lads. I have a brewbelt and a malt tin with a 30 watt bulb. Which has been plenty even on the coldest of days.

Great post.   I can fit my buckets in, but the airlock pops up to the outside edge of the freezer box.     Freezing my airlock before the the wort cold crashes.

Any suggestions on this fridge? I think the little feeder pipe is steel, its hard for sure.

Great writeup, looks good.




****>>> Warning <<<***

Make sure that you unplug the fridge (or any electrical device) before you start working on it.

Why not rig up a thermostat to your heat tube to switch it automatically?
Something like this? http://ie.rs-online.com/web/p/thermostats/7334723/

Or even a simple room stat?

@ Motorbikeman. Are there two coolant lines running to your chiller plate? If they are both on the right side you could bend the plate flush with the right side wall. You would have to move the thermostat but that shouldn't be too big of a deal.

@ pob You are spot on to mention unplugging the fridge before attempting this. Of course electrical safety is the number one reason but also if the plate is freezing it is more brittle and likely to kink or leak. I will edit the main post to include this step.

If you have a fridge like this.  A Powerpoint fridge.   Dont feckin touch it.   
As soon as I messed with it, even gentle like,  I heard a hissssssssss.   Now I have to take it to the dump.

I did get my hands on this little beauty from averts for free!!  Beko Glasser undercounter fridge.

If you cant be bothered to convert or have one of the fridges like the first pic.  There still is hope. 
There is a plastics firm in Naas industrial estate who sell 25l buckets that fit.. http://complaspackaging.ie/ 6.50 a bucket with lid.

That beko looks great Motorbikeman.  ;D

I think once the coolant lines themselves aren't bending the plate should be able to take a bit of flex.
