  • Building a coil system

    I am trying to make a customized Jockey Box/ cooling system. I have a section of stainless steel tubing (40' of .375 X .035 T 316L WLD -A-269) without the end connectors. I have a cornelius keg setup with everything but a cooling system; all have standard fittings.
    I think I need 2 - 3/8" grommets (787G), 2 - 3/8" ferrules (787F), then what? Or am I completely off?
    Q: What other equipment do I need and how do I connect it to the rest of my setup?

    Not certain what the T 316L WLD -A-269 means. The 40' coil sounds like a 38" O.D. stainless coil. For the entry point, use the 3/8" bore shank with the 787G and 787F. From the keg coupler, use the 6' vinyl jumper to the shank.
    Most commercial set ups utilize an additional 20' of 1/4" O.D. stainless attached to the 3/8" as a restrictor to control the flow. You can simulate this with 10' of coiled 3/16" I.D. vinyl. Use a short 4" piece of 3/8" I.D. vinyl and clamp to the outlet end of the 3/8" O.D. stainless. Clamp a 3/8" x 1/4" splicer to this vinyl and to the 3/16" I.D. vinyl. Attach the other end to a 3/16" splicer under a hex nut with washer to a faucet shank. Start pressure about 25 PSIG and adjust for desired flow. This system is not intended for long term dispensing (over four hours).

      I am building a small scale prototype as soon as possible. I envision the coils being several thousand feet long to store off peak power, it may look like a large water storage tank with multile coils inside with the wind turbine on top instead of the picture I provided.
