kwsurfer Plattenwärmetauscher
Plattenwärmetauscher mit 5/4 Zoll Anschlüssen - leider noch nicht ausprobiert, macht aber einen wertigen und stabilen Eindruck, Ich habe schon vorher ander Wärmetauscher gleicher Bauart gekauft, die Funktionieren einwandfrei.

Darren Mr.
Awesome equipment. This is the first time I use a flat plate heat exchanger. It performs way beyond my expectations! The 5 x 12 x 50 plates has NO trouble transferring 500,000 Btu per hr at about 30 gpm and 33 ⁰F temperature change on the boiler side. I am running the floor circuit through the other side at 13 gpm and 77 ⁰F temperature change. I believe the transfer efficiency is 95% or better. It is much heavier than I expected. That is a good thing! Nice and solid. Clean, precise threads. No leaks. I used Hydraulic Female Pipe Thread Swivel fittings as compact, sealant free, leak free, connections.
Very happy! Would definitely buy again.

bad machine work faulty item
I have ordered many things from Vevor and never had any issues until this order. This would be a quality piece if the fittings were machined correctly. The correct NPT fittings would not thread on to this heat exchanger. I contacted Vevor about the issue and they offered to refund about 1/3 of the price, I refused and they offered about 2/3, I refused and they refunded me 2/3 anyway. I told them that wasn't acceptable and they then offered to refund the remainder if I confirmed but they closed the chat and I wasn't able to confirm. I didn't have to confirm the first refund so I don't know why I had to confirm the second refund. I had to start another refund ticket and they promptly responded that they issued the refund but that hasn't happened yet.
