Low Cost Chiller Ideas

Tired of filling my open end dewax columns with dry ice, would be so easy to just flip a switch and have it be pumped with fluid at “cryo” temps. But im not sure a recirculating chiller is worth the $$$ just cause i wanna save 5 mins. Personally ive been pondering if dry ice in alcohol w/ a submergible water pump would work, but have no clue how a plastic pump would do soaking in alcohol… Possibly a fire hazzard too… dumb idea? Are there small pumps designed for this i havent hear…

or open up a Jubalo and look for a label
