Productdescription Oldorid Durona

Here you find the description of the DURONA Seamless Ventilation Duct The top product of Oldorid is the DURONA Oldorid Durona Flat ducts The DURONA guaranties absolut superiority in safty and life time. How do we achieve this? The DURONA eliminates the troublesome longitudual welding seam, which is often the weak point of the ducts. This duct is woven in one piece even in a version of 100 meters and more. Welding seams and other potential failure sources are eliminated. Even at high temperatures there is no disconnection any more. The DURONA guaranties high tensile and tear strength. The fabric is light weight but in the same time extremely durable. Not only by peak loads but also by long term loads, particular strength is assured. In addition to these advantages of the DURONA the time of integration is reduced by 5 compared to the normal time.  This is a particular economic characteristic of the top product DURONA.

Product description Flat duct

Oldorid flat ducts are designed mainly for blowing ventilation of air and other gases and allow tight duct lines. Oldorid Flat ducts They consist of one longitudinal welded seam of flexible material which is optimized for every particular use. Oldorid flat ducts are used in mining and tunnelling industry, mainly for blowing ventilation. They serve there for completely tight transport of air and other gases. Oldorid ducts have proven their efficiency successfully in years of operation. Here you will find the technical specifications

 

Productsdescription shaft ducts

Shaft duct are used for particular applications in mining and tunnelling shafts. The vertical ventilation system requires a stable suspension system (for instant: steel ropes with a high tensile strength and for heavy loads. In the normal configuration two  8 mm zinked steel ropes are connected to the shaft duct on opposite sides. The fixation is provided by steel clamps in S-hooks which are fixed to the shaft ducts.  At the end of the shaft duct a zinked consistant steel lock is fixed to each of the ropes. On the other end of the shaft duct a special rope clamp  is fixed. Bei der Montage mehrerer Schachtlutten kommen Verbindungsschellen zum Einsatz. Sie werden von den Tragseilen und voreingestellten Spannschlössern entlastet. Gleichzeitig halten sie die Schachtlutten, die durch Ösen und Haken an der Schachtwand abgestützt sind, stabil. For the connection of serveral shaft ducts, couplings are used. The loads are carried by the ropes and steel clamps. In the same time they stabilize the shaft ducts which are connected to the walls by hooks and eyelets. By this system a reliable ventilation of 1000 meters and more can be achieved Here you will find the technical specifications
