In this video, we show how the hydraulic (water expansion) process is applied in the production of fan coil units (FCUs). This critical step ensures a tight bond between the copper tubes and aluminum fins, improving heat transfer performance and product durability.
Hydraulic expansion, also known as water expansion, is widely used in the теплообменник и HVAC industry. Watch the full process from tube insertion to high-pressure water expansion and final inspection.
As a supplier of fin press lines and fin dies, SINOAK is committed to supporting high-efficiency heat exchanger manufacturing.
