Blichmann Engineering Large Herms Coil is a 9.5 inch tall coil of 32ft long tube and is made with 304 Stainless Steel.
This large HERMS Coil is used in 15-55 gallon kettles. You will need to have a step down drill bit or a 13/16" knockout punch to put the hole in with. All this information is included in the instructions. Included are 2 1/2" QuickConnect Elbows.
When you have your HERMS coil installed, heat your hot liquor tank and recirculate wort through the HERMS coil. This will allow you to maintain a constant temperature. Using a whirlpool in the HLT will improve heat transfer to the HERMS Coil. This will increase efficiency of your strike temperatures. Reducing the time to reach your strike temp by 30-50%. Huge time saver!
