C+Duct. The energy-saving-duct.
C+Duct. represents a new generation of duct parts for an energy-efficient operation of air-conditioning systems. Thanks to innvovative technology in the manufacturing process, the hygienic requirements according to VDI 6022 and the tightness requirements according to DIN EN 1507 can be smoothly met - a proper installation assumed. A significant fature of the new technology is the automatic bordering of the flange sections (pdf3- section) directly from the sheet metal coil.
Unlike in other comparable technologies, forming and stabilization of the flanges is made in a single pass without additional corrosion-prone bonding techniques. To achieve the tightness class C according to DIN EN 1507 a silicone-free permanently elastical sealing compound is injected in the folding bag by machine already during contouring. Aditionally, a new internal sealing element reduces leakeage losses in the corner area of the fold.
This solution provides a secre basis for the hygienic safety of the air flow to be conveyed according to VDI 6022. Although the flange sections are brodered we deliver our ducts at a standard length of 1500 mm.
