Hey everybody, this is John McCoy, production manager at G&D Chillers. I’m going to run through exactly what a Y strainer is and what it does to help you guys understand the importance of putting one of these on your chiller. What a Y strainer is, it’s basically just a straight through fitting that is installed on the return line at the chiller. Direction matters: they are directional. So, pay attention to an arrow in the direction of flow when it’s installed. What it does is basically, it’s a 20-mesh Y strainer that’s got a mesh on the inside of it. And the flow has to pass through that mesh, that screen, before it can get back to wherever it was going. What that screen does, it catches all the particles, contaminates, anything that might be floating around in your system, prevents it from getting back to the chiller. It’ll protect the pumps, the heat exchangers, all the necessary components inside the chiller to ensure they don’t have any contaminants running through inside of them. One thing to pay attention to when choosing the Y strainer that you’re going to need is, it’s a good idea to up size that by about a half a size, which means if you’re running two inch mainline throughout your system, you want to run a two-and-a-half inch Y strainer. That way there’s no flow restriction. If you’re running a one inch, run an inch-and-a-half Y strainer. I’ll keep everything moving freely throughout your system. Contact Us
