PIR Duct

Category:

PIR (Polyisocyanurate) ducting is a lightweight, pre-insulated air duct system made from rigid PIR foam panels covered with aluminum foil or other protective coatings. It is designed to provide excellent thermal insulation, fire resistance, and energy efficiency in HVAC (Heating, Ventilation, and Air Conditioning) systems. PIR ducts replace traditional metal ducting by offering a corrosion-free, airtight, and lightweight solution.

Description

Dimensions:

  • Panel Thickness: 20 mm, 25 mm, 30 mm, or 40 mm PIR foam insulation
  • Panel Size: Typically 1200 mm x 4000 m
  • Duct Size Range: Customizable according to project requirement
  • Thermal Conductivity: ~0.021–0.025 W/m·K for excellent insulation

Material:

  • Manufactured using premium-grade stainless steel, renowned for its exceptional durability, corrosion resistance, and hygienic properties. Custom material options are also available upon request to suit specific project requirements.

Applications:

PIR ducting is widely used in:

  • HVAC Systems: Ensures efficient air distribution in residential, commercial, and industrial buildings.
  • Cold Storage & Refrigeration: Maintains low temperatures while minimizing energy loss.
  • Clean Rooms & Laboratories: Provides airtight and hygienic air circulation.
  • Hospitals & Healthcare Facilities: Helps maintain sterile and temperature-controlled environments.
  • Food Processing & Pharmaceutical Industries: Used where clean air and insulation are required.
  • Airports, Malls & Large Commercial Spaces: Reduces operational energy costs in large-scale HVAC systems.
  • Marine & Offshore Applications: Corrosion-resistant properties make it ideal for ships and offshore facilities.

Features:

  • Lightweight & Strong: Up to 75% lighter than traditional metal ducting.
  • High Thermal Efficiency: Superior insulation properties reduce energy consumption.
  • Airtight & Leak-Proof: Minimizes air leakage, improving system efficiency.
  • Fire-Resistant: Self-extinguishing and meets international fire safety standards.
  • Corrosion-Free: Unlike metal ducts, PIR ducts do not rust or degrade over time.
  • Fast & Easy Installation: Pre-fabricated panels reduce installation time and labor costs.
  • Low Maintenance: No need for additional external insulation.

Specifications:

  • Core Material: Polyisocyanurate (PIR) foam
  • Outer Surface: Aluminum foil, protective coatings, or reinforced layers
  • Fire Rating: Meets ASTM E84, BS 476, and other international standards
  • Moisture Resistance: Highly resistant to moisture and mold growth
  • Airflow Resistance: Smooth internal surface ensures minimal pressure drop
  • Joining Methods: Flanged, gasketed, or adhesive sealing
