Как предварительно окрашенные панели из оцинкованной стали для воздуховодов улучшают работу наружных систем отопления, вентиляции и кондиционирования воздуха?

In modern HVAC duct systems, pre-insulated duct panels—especially pre-painted GI duct panels—are increasingly widely used. This is particularly true in large commercial buildings, industrial facilities, and rooftop HVAC systems, where ductwork must not only provide excellent thermal insulation performance but also offer enhanced weather resistance, structural strength, and long-term stability. As a result, pre-insulated duct […]

Why Pre-insulated Ducts Are Replacing Traditional GI Duct Systems

1. Shift Toward Integrated HVAC Duct Systems In modern HVAC systems, duct selection is shifting from traditional solutions to more efficient integrated systems. Compared with traditional galvanized iron (GI) ductwork, pre-insulated duct systems are becoming a mainstream choice in HVAC applications. These systems offer improvements in structure, energy efficiency, and installation. 2. PIR/PU Pre-insulated Duct […]
