10-gallon insulated water cooler with drilled lid for holding the ice water and submersible pump. The submersible pump circulates the ice water through the cooling jacket to keep your fermentation temperatures in line. You can also use a March pump or Chugger pump by replacing the spigot with a bulkhead fitting, and connecting your pump to the fitting. Connect your pump to a temperature controller to thermostaically control fermentation temperatures. We have obtained +/-0.4 degree F control with the Auber Instruments controller (it has 0.1 degree F control settings).
