Linhas de Espumação de Painéis para Gabinetes de UTA para Fabricantes de Equipamentos HVAC
Os gabinetes das unidades de tratamento de ar (UTA) para HVAC requerem painéis sanduíche espumados com PU para isolamento térmico e amortecimento acústico. Fornecemos a linha de espumação de PU, os moldes de espumação e o sistema de material isolante para a produção de painéis de gabinetes de UTA — espessura de painel de 30 – 150mm, 50 – 500 conjuntos de gabinetes por dia.
In one line
2 projetos OEM de gabinetes HVAC entregues — com foco exclusivo na etapa de painéis de gabinetes isolados, o segmento específico da produção HVAC em que a expertise em espumação de PU mais importa.
Scope: we supply only the PU foaming line and moulds for HVAC air-handler (AHU) cabinet production. We do NOT supply compressors, condensing units, refrigerant systems, or full HVAC plant turnkey solutions — contact a dedicated HVAC OEM integrator for those.
Real Pains We Hear from Buyers — and What We Ship to Solve Each One
Four pains every HVAC AHU cabinet factory founder brings us. Our line clears each — staying inside scope (cabinet only, not the full AHU plant).
AHU cabinet panel thermal bridge — building HVAC engineer rejects spec on heat loss calculation
Thermal bridges form at panel-to-frame joints when PU foam doesn't reach edges evenly. Our cabinet mould design fills the full perimeter to ±0.3 mm thickness uniformity. Foam k-factor 0.022–0.024 W/m·K verified shot-by-shot. Joint thermal break gasket integrated into mould geometry. Field-measured U-value: 0.5–0.7 W/m²·K (well below 1.0 W/m²·K threshold).
AHU acoustic spec (LEED healthcare hospital projects) — STC 40 minimum, my current panels only hit STC 32
STC is foam density + panel thickness + panel-to-panel joint design. We tune PU formulation to density 45–50 kg/m³ (vs standard 38–42), panel thickness 50–80 mm, and ship the acoustic test chamber (USD 65K–140K) for ISO 717-1 STC measurement on every cabinet variant before shipping to LEED/healthcare buyers. Field STC: 42–48.
Project-based orders with different sizes per building — modular tooling not flexible enough
Our foaming moulds are reconfigurable ±20% from base mould dimensions (e.g., 1.2×2.4 m base mould covers 0.96×1.92 m to 1.44×2.88 m). Truly custom sizes outside ±20% range need new mould inserts (USD 60K–140K). Most AHU factories carry 3–5 base moulds covering 80% of project orders, plus inserts for major repeat sizes.
Cabinet supply scope vs full AHU plant — buyer keeps asking for fans, coils, motors which I don't supply
AHU plant = cabinet + coil + fan + filter + motor + controls. We supply ONLY the cabinet (foaming line). To keep buyer expectations clean: we ship a scope-boundary letter with every quote stating what's in scope (cabinet panels + foam + finish) and what's out (mechanical components). Most AHU brand customers source coils from Bohn/Bitzer, fans from Ziehl-Abegg/EBM-Papst, motors from ABB/WEG independently.
