[Tianjin Jinzhong Ji HVAC purification equipment to recommend the star product - the spiral duct of Use] style main uses are as follows: (a) air, including ventilation, such as sending fresh air and exhaust, this range is very wide pipeline prices, such as the factory floor, production sites of air, due to the need for harmful gases exhausted to the outside, they need to outdoor air delivered to the room. Then we should use large and small flow of air pressure pipes, spiral duct on the most suitable for use under normal circumstances galvanized iron pipes, corrosive and humid places to use stainless steel tube. (2) send the cold, the most common is the central air-conditioning duct, the duct need to add insulation. Spiral Duct insulation materials can be put in the pipeline project, the looks beautiful.
