X her is a company which manufactures coaxial exchangers.Coaxial Heat Exchangers (1/3 to 20 Hp) on Doucette Industries, Inc.
I found a tube in tube they make FW2, list 780$, rated for a 2 hp unit just the other day for 100$.
Looking for a R22 heat pump now, madmodification to R-290, hope to make a Reverse Cycle Chiller like Reverse Cycle Chiller
Have been trying to find pictures of the inner guts of one of these things for a while, and still looking while I compile components. I think this FW2 is a great start thou.
Cheers all
