Tunnel Housing for IR Drying/Curing Tunnels | Specifications & Verification

Product Specifications

Technical details and manufacturing context for Tunnel Housing

Definition

Tunnel Housing is the main structural component of an IR Drying/Curing Tunnel system that forms the enclosed passage through which products travel during the drying or curing process. It provides thermal insulation, contains the infrared radiation, supports heating elements and conveyor systems, and maintains controlled environmental conditions for efficient heat transfer to the processed materials. The housing is typically constructed from stainless steel and insulated steel panels, with thermal insulation materials integrated into the walls. Key parameters include internal width (600–2000 mm), internal height (300–1200 mm), section length (1000–3000 mm), wall thickness (1.5–3.0 mm), maximum operating temperature (80–200°C), thermal insulation thickness (50–150 mm), surface flatness (±1.0 mm/m), material grade (SUS304 per ASTM A240), weight per section (500–3000 kg), and IP rating (IP54–IP65 per IEC 60529). These values are reference ranges; actual specifications must be confirmed with the manufacturer for the specific model and application. The housing is designed to be modular, with sections that can be transported and assembled on site. It must accommodate the product dimensions and airflow requirements, and its structural integrity is critical for safe operation. Regular inspection for thermal degradation, corrosion, and seal integrity is recommended. The housing does not include the IR emitters, conveyor, or ventilation equipment, but it provides the support and enclosure for these components. Verification of material grades and standards is essential during procurement.

Working Principle

The tunnel housing creates an enclosed chamber that contains infrared radiation emitted by heating elements, preventing energy loss to the surrounding environment. Its insulated structure maintains consistent temperature profiles along the tunnel length while providing structural support for all internal components including IR emitters, reflectors, conveyor systems, and ventilation equipment. The insulation reduces heat loss and keeps the outer surface temperature safe for operators. The housing's dimensions and material properties are selected based on the required process temperature, product size, and environmental conditions. Proper sealing and flatness ensure uniform airflow and prevent contamination.

Frequently Asked Questions

What materials are used for Tunnel Housing?

Common materials include stainless steel (typically SUS304 per ASTM A240), insulated steel panels, and thermal insulation materials. The specific grade and thickness should be confirmed with the manufacturer for the intended application.

What is the maximum operating temperature?

The reference range is 80–200°C. For temperatures above 200°C, special insulation is required. Always verify the exact rating with the manufacturer for your process.

How is the housing installed?

The housing is modular, with sections typically 1000–3000 mm in length. Sections are joined on site, ensuring proper sealing and alignment. Installation should follow the manufacturer's guidelines.

What maintenance is required?

Regularly inspect for thermal degradation, corrosion, and seal integrity. Check surface flatness and ensure insulation remains intact. Follow the manufacturer's maintenance schedule.
