TDF System
TDF is a flanging system that consists of forming a flange profile on the duct ends, thus made out of a sheet from which the duct is fabricated. TDF is a 4 bolt duct connection system that eliminates time wastage. Rather than using separate connectors to assemble your system, TDF flanges are roll formed onto duct during the manufacturing process. This connection minimizes leakage and installation costs. These TDF flange eliminates the additional internal sealing around the edges of duct & thereby saves the labour & material.
- Highly accurate flange profiles and components ensure ease of fitting and high-quality assembly.
- A Recessed groove on flange and radial groove on corner pieces for proper gasket seating.
- Snap fit corner pieces to allow easy fitting at sites.
Slip & Drive Cleats System
Slip and Drive Cleats system is generally used for low-end, less-critical applications. Traditionally, only the Drive cleats ("C") which are positioning cleats were used for all four sides. This was giving a poor joint. The Slip cleats ("S" / "Standing S") on the alternate opposite sides provide the moderate rigidity to the joint. While installing, Drive cleats are always fitted on the shorter sides and Slip cleats on the longer sides.
MS Angle Flange System
One of the most widely used types of ductwork in HVAC (Heating, Ventilation, and Air Conditioning) systems is the rectangular angle flange duct. This type of duct is designed with angle flanges fixed to the edges of the duct sections, allowing for a strong, rigid, and easily connected system.
