Be sure to wear gloves when working with them though as the plate edges will definitely cut your hands. Also, be sure to over-size what you THINK you need as the BTU ratings are "optimistic". Consult some other online plate heat exchanger datasheets to get an idea of the GPM you need to actually achieve the heat transfer you're looking for. ## Features - 【Premium Quality】Our plate heat exchanger is made of high quality 316L stainless steel which are brazed together by 99.9% copper at the edges for a reliable and rugged part to form a durable, integral piece that can resist leakage and withstand high pressure and temperature. - 【Convenient For Use And Energy Saving】Smooth Thread makes a easy, quick, flexible hookup.
