SYSTEM OVERVIEW
The basic principle of the Fermentation Temperature Stabilization System (FTSs
2
) is to pump chilled
water or glycol through the immersion coil when the temperature of your wort is greater than the controller
set-point. The system is designed to use chilled ice water from a common cooler or glycol chiller. In this
conguration, the submersible pump will be placed in the bottom of the cooler.
The FTSs
2
is intended to be a low pressure closed loop system. Water or glycol pumped from the cooler
to the fermenter is then returned to the cooler to be used again.
If your setup requires more distance from the fermenter to the cooler, you can purchase common vinyl
tubing at most hardware stores. The pump is capable lifting the water up to 10 feet. Pumping beyond
10 feet will negatively affect efciency.
In a heating mode, the controller will activate the low wattage heater, which will in-turn begin to slowly
raise the temperature of the liquid volume starting at the fermenter’s cone. From there, convection will
foster the newly introduced heat to radiate up to the remaining liquid volume not in direct contact with
the cone. This key characteristic insures that hot-spots don’t form within the fermenter.
