Portfolio entry and equipment for sale

Im just documenting a build as part of a portfolio of my work. I found this vessel and negotiated its price for a client as well as made many modifications. I used a salvaged compressor from a whole house ac unit and some thermocouples, pressure sensors, arduino, plus a very nice electronic expansion valve,

to create a heat pump that used the jacket of the pressure vessel as the evaporator. Creating a refrigerated vessel that could chill hundreds of liters of ethanol to -55c in only a few hours. and now its for sale again without the refrigeration system because its not able to be moved with it in situ but i could set it up at its new home potentially. if interested you can message me here or plant2pipe@gmail.com
