HERMS Design

>> Sunday, March 01, 2009

I'm in the process of building a HERMS system. The brains of the system is the BCS-460 Programmable Logic Controller from Embedded Control Concepts. It will be composed of the basic elements present in other HERMS systems:
  1. Hot Liquor Tank (HLT) - 5 gallon Rubbermaid cooler heated by a 1500 watt 120 volt water heater element
  2. Heat Exchanger (HX) - 2 gallon Rubbermaid Cooler heated by a 1500 watt 120 volt water heater element and consisting of 10 feet of 1/2" copper tubing
  3. Mash / Lauter Tun (MLT) - 10 gallon Rubbermaid cooler
  4. Pump - Brand a model to be determined
  5. Boil Kettle - 8 gallon
The controller will be used to turn the heating elements and pump on and off at various times throughout the brewing process.
