Chilling the internal coil on my Solvent Tank

I’m running a small CLS with nitrogen push and a CRC. I have a 50# solvent tank with an internal coil and a vacuum jacket. I plumbed the internal coil for chilled water, using a 500 gph submersible pond pump, filled a big cooler with ice and water, and let it run. Monitoring the return water temp it got down to 33.7F. That’s as cold as I’d ever expected with just plain water and ice. As I thought about it I wondered. With this is running while I’m recovering from my coil, which’s in dry ic…

How To Safely Pump Freezing Acetone or Isopropyl with a Fishtank Pump?

How do you safely move around freezing Isopropyl or Acetone with a fishtank pump?

Alternative methods and cryo fluids are welcome for chilling jackets.
