Especificações Técnicas
Phase-Change Thermal Engineering
Enhanced stainless steel surfaces are designed to overcome the low heat transfer rates of boiling liquids. Nexmek's rolling blades create T-shaped tunnels that trap vapor and promote rapid bubble formation, reducing the temperature difference required for heat transfer and significantly increasing the overall efficiency of the exchanger.
- Up to 4.5x higher boiling efficiency than plain tubes
- Significant reduction in total heat exchanger footprint
- Engineered for high-pressure industrial refrigerants
