The Still Spirits T500 Copper Condenser. There has always been a vigorous debate over whether copper or stainless steel is the best material for a still. Now with a redesigned outlet block, pre-packed with saddles, redesigned column nut, 2 different tap adapters, in a new craft carton. The Still Spirits Turbo 500 reflux condenser works on the principles of ceiling temperatures, where it prevents chemical substance above a certain boiling point being processed. Unlike other reflux condensers on the market, the Turbo 500 works with a focus on the water flow and controlling the temperature of the water flow out. Assuming that the temperature of the water flow is stable, it is able to create a ceiling threshold temperature based on the water flow out.
