1st stage phase change with R22 gas normally can hit around -40C to -50C. Well, it also depends on gas that is being used. And depends on the compressor too. Bulkhy's xillixx able to drop around -47C. Lotsa things need to be done to get a very good phase change systems. Need able to handle load the most efficient. Anyway, a triple stage would cost triple arms and legs. R507, R404 are hell expensive. Expect more than RM500. Bulkhy used to have a plan on building cascade. But he has better things to do, his career. Btw, I'm sure Bulkhy willing to help you out dude. Good luck!
Still, for short bench. DI and LN2 is the best. Since Winnie/Venice has bugs on subzero temp, DI is the best. So arj, you have hit your wall or you need more DI?

Sorry arj, had to tumpang your thread again.. yes c9, bulkhy did told me he's willing to help, in fact he even promise a return to the xtreme cooling club

..

, Your xillixx still up and running? I'm not ready for cascading yet, mebbe try out the 1st stage phase first.. one refrigerant equipments and parts supplier in melaka can help me out getting the parts and labour for the kit.. right now still sketching and calculating

.. thank you for the info man/maam.. nice butt by the way, yours
