Recommended cooling jacket surface area vs volume. Black polypropylene cooling/heating sheets:- Made of polypropylene, they work with cold or hot water, and with glycol solution. Intended for food use, they are odourless, they do not pollute and do not fade. They are 308 mm wide and can be wrapped externally around a tank, or immersed in any food or oenological product. Connections are 1.5" bsp male threads. The heat exchange efficiency of the PP-sheet is only about half that of a stainless steel jacket, so it's important to wrap an insulation blanket around the outside.
