Water Cooling Coil for Air Handling Unit
Advanced Technology for Superior Performance:
1. The fins are manufactured to high-quality standards, with various flare positions including plain and wave types.
2. Fin edges can be straight or rippled depending on the application requirements.
3. All coils undergo 100% leakage testing and are cleaned inside and outside in a heated oven with air circulation, then charged with nitrogen.
4. Mechanical bullet expansion ensures efficient heat transfer between copper tubes and fins, enhancing performance in condensers and evaporators.
5. High-quality raw materials are sourced globally to produce heat exchangers that meet international standards.
6. Available copper tube diameters include 7mm, 7.94mm, 9.52mm, and 12.75mm.
7. Aluminum foil is available in blue color with hydrophilic and bio-friendly properties.
