KLIMAOPREMA PZ Prismatic Silencer

KLIMAOPREMA PZ rectangular sound attenuators are designed for air conditioning and ventilation systems. Splitters are made out of non-flammable, sound absorbing rock wool. Significant sound attenuation occurs in frequency range between 63Hz and 8000Hz. Technical Specifications: - Frequency range: 63 Hz - 8000 Hz - Maximum operating temperature: 250°C - Air velocity resistance: up to 20 m/s - Pressure drop reduction: up to 30% - Maximum sound loss: 40 dB - Splitter thicknesses: 100 mm, 200 mm, 300 mm - Standard gaps: 50 mm, 100 mm, 200 mm Material Properties: - Absorption material: Rock wool, non-flammable class A2 according to HRN 4102 - Casing material: Galvanized steel - Special request: AISI 304 or AISI 316L stainless steel Special Options: - Glass fibre silk (S): 0.12 mm protective cover - Reflective plates (RS): Better attenuation at 250 Hz frequency - Perforated plates (PS): Protective plate for velocities above 20 m/s Performance Advantages: - Particle erosion resistant splitter surface - Aerodynamic shape reduces pressure drop up to 30% - Effective sound reduction in wide frequency range - High temperature resistance - Modular design for flexible sizing Installation: Attenuators heavier than 300kg are supplied in two or more sections, each single section lighter than 300kg. On special request, can be made in non-standard dimensions.
