Steam in the spiral wound tubes and high-speed flow of constantly changing flow conditions, the formation of strong turbulence effects, making the full exchange of hot and cold, the ideal state heat transfer coefficient up to 14000W / m • ℃.
Dairy Queen branch in the use of SECESPOL Duerbote heat exchanger to provide heat to other process point of water, greatly reducing the original temperature time to stabilize the water temperature is more important for companies to save nearly 15% of the steam usage, annual cumulative cost savings for users of steam up to several hundred thousand dollars.
