I have about 15m or so of 1/4" OD copper tubing that I made into an immersion chiller a few years ago, and never used because of flow restriction. I want to chill a 40L+ batch on a regular basis. The idea is to split this into smaller loops (e.g. 1x around the inside of kettle) and solder each end to an upright 3/4" or 1" manifold to increase the overall rate of flow through the chiller. I want to use this inconjunction with a march pump whirlpool.
Has anyone seen something similar, or done something similar? Comments from anyone engineering savvy? Would the flow be more even if the manifold outlet was at the bottom (with a U bend) rather than the top as in diagram?
