PIR预绝缘风管与镀锌铁皮风管的区别及应用
在设计暖通空调风管系统时，PIR预保温风管和镀锌铁（GI）风管是两种广泛应用的暖通空调解决方案。虽然两者都能提供可靠的空气分配，但它们在保温性能、重量、耐压性、安装要求和应用场景方面存在显著差异。PIR预保温风管与GI风管：概览 PIR预保温风管 […]
预绝缘风管密封配件完整指南
PIR 和酚醛预保温风管的密封配件决定了风管的气密性、防冷凝性能和整体使用寿命。接缝、法兰连接和切割面板边缘是空气泄漏和水分渗入的薄弱环节。GFI 提供全系列专为预保温风管设计的密封配件，包括三大产品类别：高强度铝箔密封条 […]
PIR/酚醛预绝缘风管板和密封解决方案
对于所有暖通空调通风项目而言，芯材密度、铝箔面层保护等级和全套密封件共同决定了PIR/酚醛预绝缘风管板的整体性能。因此，精心设计的预绝缘风管系统能够显著延长整个通风管道的使用寿命。为了满足如此严格的性能标准，GFI生产一系列核心产品[…]
GFI黑色PIR预绝缘风管安装完成
GFI recently completed the on-site installation of a large-scale overseas tent structure project. They installed the entire ventilation duct system with black PIR pre-insulated duct panels and received high praise from the client. This project serves as yet another flagship example of our company’s service to overseas markets. Advantages of Black PIR Pre-insulated HVAC Air Duct Panels […]
如何解决PIR/PU预绝缘风管板上的冷凝问题
Proper routine maintenance and timely troubleshooting of PIR/PU pre-insulated duct panel are extremely important. Condensation, water leakage and mold growth on ductworks will damage ceiling decorations, raise air conditioning energy consumption, and impair indoor air quality as well as project inspection results.Standardized treatment Pre-insulated HVAC Duct Panel of condensation risks and full sealing protection are […]
PIR/PU预绝缘HVAC风管上出现冷凝现象的原因是什么？
在商业暖通空调项目中，管道上的冷凝水和滴水是一个普遍存在的问题。许多客户误以为仅靠PIR/PU保温板就能完全防止冷凝。实际上，材料选择、安装工艺、密封细节以及环境湿度都会直接导致管道表面出现水汽凝结和滴水。这个问题在沿海、热带地区尤为严重。[…]
预涂漆镀锌钢板风管面板如何改善室外暖通空调系统？
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 […]
