That's not a bad idea; thanks for the helpful feedback! If nobody is interested in purchasing the heat exchanger, then that's a reasonable backup plan.
Hello,
I have an 18", 60 plate counter-flow heat exchanger for sale. The model is B3-36A-60 with 1/2" Male NPT connections. The 1/2" NPT option enables more versatility with connections. You can find more details at Duda's website:
