Corrosion-Resistant Aluminum Tubes for HVAC Systems

Overview

Designed to withstand harsh HVAC environments, our Aluminium Tubes for HVAC Systems offer superior resistance to moisture, chemicals, and thermal stress, ideal for air conditioning, refrigeration, and ventilation applications. Crafted from 1100-H14 and 3003-H16 aluminum, these tubes feature smooth interiors, high thermal conductivity, and custom surface treatments, ensuring long-term reliability in heat exchange and fluid transport.

Features

HVAC-Optimized Material

Alloy Selection:

1100-H14 (99% Al): Max thermal conductivity (226 W/mK) for condenser coils, compliant with ASHRAE 90.1 energy standards.

3003-H16 (Mn 1.2%): Enhanced strength (yield 180 MPa) for refrigerant lines in commercial chillers.

Surface Protection:

Mill finish (natural oxide layer) for dry environments.

PTFE-lined (5-10μm) for corrosive glycol systems (pH 4-10), reducing fouling by 60% (ASTM D2688).

Thermal & Fluid Performance

Smooth Bore: Internal surface Ra ≤1.6μm reduces refrigerant friction (friction factor ≤0.012), improving COP by 5% in HVAC systems (AHRI 400 certified).

Dimensional Accuracy: OD tolerance ±0.03mm, wall thickness ±0.02mm, ensuring leak-free brazing (EN 10432:2018 compliant).

Installation Flexibility

Coil Formability: Supports tight coiling (min ID 10x OD) for compact heat exchangers, with memory-free material (springback ≤1° after 180° bend).

Connection Types: Compatible with flared (SAE J1926), crimped (ISO 8434-3), and welded joints, reducing installation time by 30% compared to copper tubes.

Environmental Compliance

RoHS 3.0 & REACH: Lead-free brazing and chromium-free passivation, aligning with EU EcoDesign Directive for low environmental impact.

Application

Refrigeration Systems: Evaporator and condenser coils in household AC units, commercial freezers, and cold storage facilities (compliant with ASHRAE 34 refrigerant safety).

Ventilation Ducts: Lightweight ducts for air handling units (AHUs), reducing installation load by 60% compared to galvanized steel ducts (SMACNA standards).

Industrial Cooling: Chilled water lines in data centers and manufacturing plants, leveraging aluminum’s 3x better heat dissipation than PVC.
