Hetragon™ PTFE elements can be used as structured packs for mass transfer and if necessary, for energy exchange in columns for separation of mixtures of substances which contain a liquid and gaseous component. Hetragon™ PTFE elements have flow channels arranged parallel to one another and thus ensure a homogenous distribution of the material mixture over the entire cross-section. In addition, Hetragon™ PTFE elements can be used as a support plate for packings. The product design is determined according to the application. The Hetragon™ PTFE elements are usually placed on a circumferential carrier...

Located just before the stack, the REGAVO unit recovers heat from the flue gas entering the scrubber and then transfers this heat to the cleaned flue gas leaving the scrubber to provide the gas with buoyancy to rise out of the stack and disperse. Hetragon™ PTFE element The REGAVO operates in relatively low temperatures and high levels of S03 resulting in high potential for sulfuric acid corrosion. Consequently, heat transfer surfaces are either enamel coated or made from corrosion resistant materials such as PTFE.

HetragonTM: PTFE element with hexagonal flow channels for water purification HetragonTM PTFE elements can be arranged parallel to each body for a biological reaction used in water purification. other which serve as a sedimenta- medium or for separating solids The HetragonTM PTFE elements tion area. Thus HetragonTM from fluids. com­ rises of multiple channels p elements can be used as a carrier Separation of fluid sediment Example: "counter flow principle" The fluid flows upwards while the solids, due to gravity, settle on the channel wall and slide off towards the sludge funnel
