32l Engel freezer to be used as a freezer
Permalink  

Our Engel is about 22 years old, its a 32l, MT35F-G4-D, and were about to use it as a freezer.

My research shows when the dial is set to freeze, temp the thermostat cuts in to turn the compressor off Is 18degrees, is this achievable?

 

Has anyone installed 12v fans, if so, where did the power source come from, I am guessing the fan direct in front would extract air?

At 22 years old it's probably got so much dust inside, there is a blanket covering everything. Also the fan has probably died, they only last so long & it will have a blanket of dust on the back of the blades.

 

Replacing fan in 32L Engel fridge (it has a 24v fan):

I upgraded the fan in my 28L Waeco fridge with a larger 120mm Noctua industrial fan. More power efficient than the original & pushes more air & at higher pressure.

 

The standard Noctua fans are so efficient you may as well leave it running continuously. Running the fridge as a -18°C freezer the compressor will probably be running about 40 minutes every hour.

Below is the link to my fridge modifications. It is a Waeco but the same thermal principles apply regardless of manufacturer.

We do actually pull out fridge apart to blow it out with our triple ARB compressor set-up. Like a computer, the amount of dust inside is frightening.

 

I have actually put some air compressor air-line connectors on multiple garden hoses to reach vast distance. Good enough for the task.

 

Blowing out dust with our 3 ARB compressors together with collecting dust with our Nilfisk VP600 vacuum is a weapon nations will kill for!

 

Anyway, use the Noctua fans, they are expensive, but look at the long term benefits. I have used >50 for a 3d render farm.
