Cheap walk in cooler
« on: May 05, 2016, 05:33:11 PM »
I saw this on a Market gardeners page. Thought it was worth spreading around

This is a controller to turn an A/C into a refer unit. It's $315 for the controller and another 300 for an A/C unit but it beats 2500 for a commercial model.

That sounds like a winner if it works as advertised.  We use an old freezer to age sheep but it would be nice to have something bigger.

it works great . I know 2 people that has one.  guy down the road has a crawfish pond, keeps them in a small old refer unit , like the milk company's deliver milk in. the big unit went out , he installed a a.c. unit and a co9olbot.. works as stated..  you need to have the building as they recommend for it to keep cool..insulation is the key..

Coolbot has been around awhile and everybody I talk to likes them and recommends as a cost alternative way. They admit it wouldn't work for a commercial application but for a small vegetable operation that needs cool storage they must be ok.

I am pretty sure you are talking about VinceSilverfox From Canada.  He did a thread with step by step pictures.

  Hey Dave and Bob,  this is exactly what Vince used.  For those of you that didn't or don't know him,  he built a room about 8' X 10' or so with 6" foam insulation through the walls, floors and ceiling.  Of course living where he did in Northern Canada (further north of the US-Canada border than Donald lives south of it) he also used it for a winter storage to keep from freezing.  It worked amazingly well, but then again Vince is exceptionally talented when it comes to designing and building things.   ;)

That is a good point to make Tbird. When we get around to building our processing shed the walk in cooler will need heat as well as cool. Not as much as Vince but probably 3 mos in the winter we will be heating that same space to keep things from freezing.

I'm late to the party again but this may help someone. 

Last summer I picked up an enclosed trailer (5 X 10) that was used and pretty well beat up.  It was a Haulmark brand however and that means it's quality.  I took it down to AZ and worked all winter on  it to make it into a Cooler Trailer with a 12,000 BTU AC and Coolbot. 

I installed 4" of foam on the walls, ceiling and floor as well as the swinging door. I lined it with 1/4 inch plywood on the walls and ceiling, 3/8 on the floor.    I cut a big hole and installed the A/C unit in the front end and installed a standard electric box with a pass through and outdoor marine plug in.  I then caulked all the seams and cracks and used a whole gallon of Kilz paint on the inside and then a whole gallon of porch and floor paint over that.  (I also fixed the hole in the roof from a tree branch, installed new tires, repacked the bearings and sanded and repainted the trailer frame.)
Lastly, when all that was done I installed the CoolBot unit (easy) and had a local artist put our farm logo on the exterior.

Then we pulled it back to Wisconsin and set it up next to our farm stand.  I bought wire metal shelves and screwed them to the inside. 

I had a bunch of photos but lost them when my computer bit the dust.  Here are a few I salvaged. 

A couple of notes:  Using 2" rigid foam ($20 per 4x8) was the cheapest way to insulate.  I used cans of spray foam to fill cracks and seams.  I found the niftiest thing to make cutting foam easy, a Hot Knife from Harbor Freight.  Finding 4" and 5" screws to install the foam was a pain.  And expensive.  I added big tie down eyes in the four corners so I could use the trailer for other things too if necessary.  If one wanted to spend more $$ and less time I would recommend having someone spray foam the interior with 4" of foam.  Or buy one of those kits and do it yourself.  Getting the foam on the ceiling was the most difficult part of the entire project.

So, how does it work???   FANTASTIC. 

I just put 25 heads of cabbage inside and it is 42*, right where I set it.  I cannot say how nice this will be to finally have refrigerator space!  We decided on a trailer rather than a walk-in because we can take it to the Farmer's Market, and even to the field when we harvest. 

All in All I have about 1900$ in the build with $500 being the trailer purchise and $200 for new tires.

Regards,

Jim
