Membrane winders are an important component of the ACT system. They enable safe and efficient handling of the semi-permeable membrane<\/a>, which lies over the windrows during composting. <\/p>\n\n The membrane reduces emissions and ensures stable process conditions. However, it must be regularly put on and taken off during plant operation. For example, when windrows are moved or maintenance work is carried out. As the membranes are large, heavy and often wet, manual handling would be very time-consuming. <\/p>\n\n Membrane winding devices are used here. They allow the membrane to be wound or unwound in a controlled manner and thus quickly removed from or replaced on the windrow. This significantly reduces the workload and simplifies daily system operation. <\/p>\n\n An important advantage of the ACT system is that all winding devices are designed so that they can be operated by a single person. This minimizes the amount of personnel required and allows the membrane to be handled efficiently even on larger systems. <\/p>\n\n Different types of winders are used depending on the size of the system, the available space and the desired degree of automation.<\/p>\n\n ACT offers four different wrapping devices for this purpose:<\/p>\n\n TM – Towed Machine<\/a><\/strong>Overview of membrane winding devices<\/h2>\n\n
