The FTSs uses a high quality digital temperature controller to drive the included submersible pump as necessary, delivering cooling or heating media to a custom lid with integrated stainless heat exchanger. Together with the included neoprene insulating jacket, the system eliminates the need for costly, space-taking fermentation chambers and fridges. All your customer needs to supply is the cold or hot water/glycol to recirculate! The most common set up is to use a cooler with either ice water (or frozen jugs) or an aquarium heater depending on whether cooling or heating is desired. Included with the FTSs System: Custom lid w/ 304 SS immersion chiller coil Pro grade (super quiet) submersible pump 110-240 v power supply 304 SS weldless lid mounted thermowell Tailored neoprene insulation jacket Digital temperature controller Included vinyl tubing Please Note: The lid, jacket, and vinyl tubing will be included, but not boxed with the components.
