Ideal 85 compressor mod.

a bit of a side bar show & tell of sorts...

So I was finishing up a repair on an Ideal 85 Pepsi sliders compressor deck for a customer ( the old compressor finally quit working after 65+ years) and I've anyways noticed that the design of units combination evaporator/condenser motor design left much to be desired, basically it's a single motor with a dual ended shaft that cycles on & off with the compressor, but this feature also shuts down the air circulation inside the bottle compartment and I noticed that the compressor was subjected to a bit of a "hot-soak" period between thermostat cycles.

So I decided installed a "Delay-off cycle" relay to allow the fans to run for an extra amount of time (5 minutes in this case) to help cool off the compressors case a bit more & help even out the temperature spikes in the drinks compartment, so once the Thermostat shut off the compressor the fans continue to run for a given amount of time, ( which is adjustable) note the additional little black box at the back of the compressor deck in the picture.

The circuit modification works well & really helps to smooth out the temperatures "Peak and valleys" as they say.  It was also fun adapting the new compressor to the old style side mounts, I had to fab up a sling mount to hold it between the horizontal arms, it too worked out well.

Very nice, really cool to see that you are not just paying attention to getting the job done, but improving in the process.

I'm going to include this mod. On a V23  unit I'm working on for Pat Pixley, same concept as the 85, just a (way) smaller deck.

Excellent Idea!
