Split duct ducting is usually done with 4 types of galvanized, spiral, flexible and polyurethane, each of these channels has its own advantages and disadvantages, and of course, according to the building that needs ducting, by technicians And experts are used. The second thing that has the most impact on choosing the type of split duct ducting is the cost of implementing these ducts for the builders. These four types of channels are divided into more groups, which are usually based on the appearance or the insulation used on them.
Galvanized Channel:
Galvanized channel is one of the oldest types of ducting, but it is still one of the most used channels used in split duct ducting in today's buildings. These types of channels are produced in two models, square and round. Galvanized channel has been greatly welcomed by employers due to its ease of implementation and low cost, of course, the type of insulation used on its surface will also affect the cost of galvanized channel, the best type of insulation for this type of channel is elastomeric insulation, which The cost of this type of split duct channeling greatly increases, therefore some technicians use polyethylene to insulate the galvanized channel instead of elastomeric insulation, according to the request of employers to reduce the costs of split duct channeling. The passage of time will wear out and will no longer have the necessary efficiency, which will result in a significant reduction in the efficiency of the split duct.
Spiral Channel:
The spiral channel is made of galvanized sheets that are interwoven in a rotating and spiral manner, and the thickness of the sheets used in the construction of these channels also depends on the diameter of the spiral channel cylinder. The beautiful and modern shape of the spiral channel has caused this type of channels to be used in a facade or so-called exposed form in buildings with different uses such as shopping centers, food courts, coffee shops, arcades, or even residential houses. Due to the fact that the spiral channel is designed in a round shape and the inlet of the air conditioning panel is square, therefore, to implement the spiral channel, we must first use a square-to-round conversion section so that we can transfer the comfortable air to different parts of the desired space. p>
Flexibel Channel:
One of the best types of split duct ducts is the flexible duct. The channel consists of an aluminum coating on the outside and a spiral spring and then another aluminum layer on the inside. Due to its high flexibility, the implementation of the flexible channel is done easily and at a high speed. Also, flexible channel is considered the best option in spaces where winding channeling is required and it is not possible to use galvanized and polyurethane channels. To insulate these types of channels, they use different materials such as polyethylene, glass wool, elastomer, etc., which, like other duct split channels, elastomeric insulation will be the best option to increase the working efficiency of the device.
Polyurethane channel (pre -insulated):
Polyurethane channel, which is also known as pre-insulated channel, is made in sheets and is very light, and its installation is done faster than galvanized channel. The inner layer of the polyurethane channel is formed by a type of cold injected foam and an aluminum coating layer inside and outside, which makes the cooling or heating waste to be greatly reduced compared to the galvanized channel, while the price is The polyurethane channel is lower than the galvanized channel.
