Thread: Walk in chiller monoblock units ?

I'm thinking its time to build a couple of very small walk in chillers.
One for at home and one for a farm that I hunt on fairly often.

I have access to plenty of poly panels and can make something up pretty easily as I'm a builder / joiner.
They will both be going inside fully weatherproof sheds so I don't have to worry about the exterior being weather proof.

I'm guessing some of you guys have done this and what I really want to know is a good source of 2 totally self contained monoblock refrigeration units like this
I will chase around Christchurch next time I'm in there but you never know what you guys have already done. No use re inventing the wheel





or are there any refrigeration engineers on the forum ?

I know a good fridgy but he is too busy for his mates.... Eh KJ?

I have little knowledge on gear but know if you are going to build one, build it well.
Sealed from water getting into the panelling. Good drainage and protected from the elements. Commonly being a square roof either have it covered or a way to run water off.

When doing venison we had our commercial chiller go thru so many inspections under EU guidelines and every time there were faults and cost to repair the thing. Would have been cheaper to start from scratch. That chiller could hold 120 animals.

I would also suggest framing your rails internally so you are not drilling thru panel. We had removable feet for the framing. When the weight came on it all locked up.
Especially important if having a panel floor.
When choosing a unit make sure it has a good evaporator to suit carcasses. @kiwijames will know more but most commercial units are not suited to exposed meat and can dry them out pretty quick. Not sure if they are adjustable or not.
I had a local fridgy who is a hunter build me a chiller and he had to do something to work the evaporator.
Exposed flesh in mine doesn't dry out compared to others I have seen and it runs between 0-4°c when full.

i always put carboard down when hanging animals so any blood goes onto it .then burn it when finished ,no mess to clean up

Same. I wet the chiller down then line the floor with cardboard or piss the wife off and use her extra large flexable garden buckets under the carcass.

Ref specs or real cold. Ref specs do a pre charged condensor and a nitrogen charged evaporator. For a good price.

How are you planning on controlling it?

Single phase will limit you to around 15kw. Everything above will be 3 phase.

Is it ten amp single phase or higher?

There's other questions but that's the start.

Heatcraft do a drop in unit, let me know what size you plan to make them and I can see what is available. As R93 said you need to seal the outside of the box as the cold draws moisture in, if it can’t get past the inside seal it will water log the panel and any electrical boxes so seal all wires holes and flashing on the outside. Drying out the product is caused by high temperature split across the evaporator so basically the bigger the evaporator coil the better. I’m in Wellington if I can help. James

How big are the sheds? You will need to see the air flow of the shed. Otherwise you might find that it will be inefficient and trip out on high pressure.

The sheds are huge
I'm thinking only about 5 or 6m3 internal space
So a very small single phase unit
Would like a plug and play unit with thermostat and controls included

It's really just for 3 animals at a time
Once one is chilled and broken down you shoot a few more

I'm starting to guide on one property and keeping meat in good condition can be a hassle when it's warm.

Last week it was mid 20s all week and I shot a red stag first morning
Them on Thursday I shot a 60kg boat and had to pack up and rush home to cool it down before it spoiled ... and it was bloody 30º going through North Canterbury to get home !
