PIR Pre-insulated Duct vs. G.I. Duct

Dutos pré-isolados com PIR versus dutos de aço galvanizado: diferenças e aplicações

When designing an HVAC duct system, PIR pre-insulated ducts and galvanized iron (G.I.) ducts are two widely used solutions for HVAC applications. While both can provide reliable air distribution, they have significant differences in insulation performance, weight, pressure resistance, installation requirements, and application scenarios. PIR Pre-insulated Duct   vs. G.I. Duct: At a Glance Feature PIR […]

PIR PU Pre-insulated Duct Panel

Como resolver o problema de condensação em painéis de dutos pré-isolados com PIR/PU

A manutenção preventiva adequada e a resolução de problemas em tempo hábil em painéis de dutos pré-isolados de PIR/PU são extremamente importantes. Condensação, vazamentos de água e crescimento de mofo nos dutos podem danificar a decoração do teto, aumentar o consumo de energia do ar condicionado e prejudicar a qualidade do ar interno, além de afetar os resultados da inspeção do projeto. O tratamento padronizado dos painéis de dutos pré-isolados de HVAC para riscos de condensação e proteção completa contra vazamentos são essenciais.

O que causa condensação em dutos de ar condicionado pré-isolados com PIR/PU?

A condensação e o gotejamento de água nos dutos são problemas comuns em projetos de HVAC comerciais. Muitos clientes acreditam erroneamente que os painéis isolantes de PIR/PU, por si só, podem impedir completamente a condensação. Na realidade, a seleção do material, a qualidade da instalação, os detalhes da vedação e a umidade ambiente influenciam diretamente a formação de condensação e o gotejamento nos dutos. Esse problema é especialmente grave em regiões costeiras, tropicais e […]

How Pre-painted GI Sheet Duct Panel Improves Outdoor HVAC Systems

How Pre-painted GI Sheet Duct Panel Improves Outdoor HVAC Systems?

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 […]
