few questions:
what kind of refrigeration unit is that?
what would be the HP equivalent?
how much pressure is in the lines?
how much water flow is going through the barrel?
how did you extend the length of the temp probe? (what type of wiring)

Thanks and I'm looking forward to more info on the build.

That unit meant for a crab tank: Does it have it's own chiller barrel? If not, the lines haven't been just left open to the atmosphere have they?

This is a refrigeration unit from an auto-purger off of the old Trane chiller for Sears at Lougheed Town Centre. I was doing the tear down a while back and it was just going to get tossed, so I scooped it.

As was mentioned, it is a 1/4 HP unit

I am running 35 PSI suction and 145 PSI discharge pressures.

Not sure of the water flow through the barrel. Probably around 200-350 gph. Not really much needed. I needed to make sure that the vapor returning to the compressor was cool enough to cool the windings of the motor.

The probe was extended with plain, old, run-of-the-mill 18 guage thermostat wire.

For more info, just let me know what your looking for. Don't be afraid to speak up!
