This is an early MSR XPD Cooking System with Stainless Steel pots and a heat exchanger baffle to gain more heat transfer efficiency between the stove and the bottom of the pot on the stove. The outside of the box has product info and usage instructions. I remember seeing this packaging in the stores in the early 1980's. I wanted one then when I bought my first MSR Whisperlite stove for a solo backpacking trip to Yosemite National Park. The original receipt was in the box with a selling price of $47. I just acquired it for $10 at a swap meet.
Not sure why the photo of the box top is small on the original post so let's try it again so you can see what it says...
Hi I think they had something there, heat exchangers are under used in my opinion. The Eta multifuel seems to take this technology on a step but my guess is that there is a way to go yet. Think anderson cooker with heat exchanger I may apply for a patent.
Hi, JWD, Yes, those MSR heat exchangers do actually work, and we've used our many times over the years. IF you are camping or backpacking for a long while, then it's worth taking the heat exchanger along, and it will save fuel. If you're only out of for a weekend, it might not be worth it's weight, but still helps cut down on wind problems. Fun bit of kit, that's for sure. Great find, by the way, and an outstanding price! Well done! Take care, and God Bless! Every Good Wish, Doc
I was looking for information about the use of this MSR heat exchanger; It seems useful to me. It occurs to me that placing 2 "below the bottom of the pot can serve as an efficient windshield. Reading these opinions it seems that my logic is correct.
They will work as a windshield, but there are lighter weight and less bulky windshields available. ....Arch
I used that kit to melt a lot of snow. I saw bubbles on the side of the pot with that heat exchanger. The best windscreen came with the XGK.
