Material Composition | Commercial HVAC systems | - Industry Standard: PVC (ASTM D2241) - Our Base: Copper (ASTM B32-18) ▲ - Our Advanced: Copper + ASTM G48-16 corrosion test ▲▲ | ▲▲ Copper’s corrosion resistance extends lifespan by 50%+ (vs PVC) High thermal conductivity improves efficiency | Higher upfront cost compared to PVC-based systems |
Welding Process | High-precision installations | - Industry Standard: Manual TIG (ISO 6947) - Our Base: Semi-automated (ISO 14698) ▲ - Our Advanced: Fully automated robotic welding ▲▲ | ▲▲ 99.8% defect-free joints (vs 95% manual) Consistent pressure resistance | Requires specialized equipment for automated setups |
Outlet Configuration | Multi-split VRF systems | - Industry Standard: 4 outlets (ISO 3801) - Our Base: 5 outlets ▲ - Our Advanced: 6 outlets + customizable spacing ▲▲ | ▲▲ Supports 12+ indoor units (via adapters) Precise flow distribution for large buildings | Larger footprint may require additional installation space |
Customization Options | Custom HVAC layouts | - Industry Standard: Fixed design - Our Base: Adjustable brass fittings ▲ - Our Advanced: Bendable copper + modular ports ▲▲ | ▲▲ Adapts to irregular piping layouts (e.g., retrofit projects) No need for secondary fittings | Requires skilled technicians for field modifications |
Corrosion Resistance | Coastal/industrial environments | - Industry Standard: Passivated steel (ASTM A240) - Our Base: Copper (ASTM B32-18) ▲ - Our Advanced: Copper + nickel plating ▲▲ | ▲▲ Resists saltwater and chemical corrosion (ASTM B111) 50-year lifespan vs 20-year steel | Higher cost due to plating and premium material usage |
Pressure Handling | High-pressure VRF systems (e.g., geothermal) | - Industry Standard: 150 PSI (ASME B16.34) - Our Base: 200 PSI ▲ - Our Advanced: 250 PSI (ASME B16.34 + EN 10216-2) ▲▲ | ▲▲ Supports extreme pressure (e.g., subterranean systems) Reduces leakage risks | Thicker walls increase material costs by ~20% |
