How about this? Gurk! $325! :o
But seriously, I might buy one of the cheaper ones.
That SS304 looks overpriced to me even considering connections. Also, I didn’t find manufacturer name. So, who is responsible for the promised warranty?
You can get a plate chiller made of ASTM 316L Stainless Steel, which has a better corrosion resistance, for even less. Just need to get some adapters.
