I am considering building a glycol chiller system using this tank
Thought was to cut out slots in the top so that I can lower air conditioner coils into them and then weld back into place and then seal the holes where the pipes pass through- would like to be able to stack four 12000btu AC units (14kW of cooling? not sure if I am correct here)
Then cut out two holes in the top and weld in 2 5 gal stainless pails that can have ethanol poured in to chill, suction tube from air powered pump will be lowered in to remove ethanol post extraction.
I’d like to get this system chilled down to -45c.
Everything gets nicely insulated and encased, and the included fuel pump can supply glycol coolant to my rotos (10L 20L 50L) and 4in WFE condenser coils. planning on having a steel coil submerged in dry ice before each condenser inlet as well.
EDIT thinking maybe just run 9in wide steel tubes down the middle and weld them to the bottom for ethanol reservoir/soak tanks, instead of buckets. or maybe 4x six inch tubes.
