Here at Celina we fancy ourselves fairly knowledgeable about industrial fabrics. From the standard PVC vinyl that is the mainstay of our commercial production lines to tricot and biological/chemical resistant fabrics, we’ve done massive amounts of trial-and-error study and research into sealing and sewing the products.
When you are considering new ducting, the movement of the air within the duct can help you to choose exactly what style and type of ducting you’re going to be hunting for. Not so much the direction of the air, but more how that air is being moved. Much like how meteorologists talk about high pressure and low pressure fronts, the method of air movement is going to greatly impact the fabric and reinforcement choices you make.
The Joint Enterprise Research, Development, Acquisition and Production/Procurement (JE-RDAP) program is tasked with supporting the research and development in the field of Chemical, Biological, Radiological, Nuclear, and High-Yield Explosives (CBRNE) items. This includes defense systems, capabilities, equipment, supplies, and general materials that in one way or another are in used in situations that deal with CBRNE circumstances. To fulfill their goal, JE-RDAP occasionally issues contracts for their research efforts.
Each quilter takes up a fair amount of space, to be sure. The rear of the apparatus has the spools and holders in order to create the layering that is required. Depending on the product, the arrangement can be changed in order to accommodate multiple layers, partial layers, additional material strips, and so on. All of this is fed into the main sewing unit, equipped with many lines of sewing needles that have their own controls and thread feeds.
Insulated Ducting is made with wire reinforcement, keeping the duct in shape no matter where it’s installed. Sandwich ducting has this wire added while the duct itself is being fabricated. This puts the wire within the four layer seams, and can still have wear stripping added for extra protection. Duct-in-Duct is made with a standard wire reinforced duct on the inside, and doesn’t need additional wire on the outside.
While I’m not advocating for you to add air lock systems to barns (although imagine the super-sci-fi looking farm you would have), it does point out that there are many small ways in which simple additions can have great effects on heating and cooling systems. While it may not seem like much, Fan Covers from Celina Tent can keep out a large amount of chilly air over the coming winter.
As Celina Industries develops and expands upon our ducting line, we increasingly come to like the idea of wear stripping. And when you get right down to it the reasoning makes sense. Whether we’re looking at keeping the ducting’s shape or designing a construction program to make tubes for high-damage areas, having an additional layer of protection can bring additional years’ worth of life to a duct.
maintaining your hay tarp isn’t as hard as it may seem. There doesn’t need to be a massive amount of hardcore, engineered pulleys and anchors or complicated rope knots to keep your hay tarps intact and in place. Through the already installed hardware, keeping your hay tarps right where you want them is easier than you’d think.
