Advanced continuous Serpentine coils for evaporative condenser and closed circuit cooling tower

SPL’s coils feature an exclusive design which assures maximum cooling capacity. The airflow through the coil is counter-flow to the fluid flow, providing the most efficient heat transfer process. A special coil design is utilized to reduce the air pressure drop through the unit while maximizing tube surface area and increasing its heat transfer capabilities. The uniquely shaped tubes of the coil are staggered in the direction of airflow to obtain a high film coefficient.

The new latest cooling towers utilizes patented elliptical fin coils design which assures even greater operating efficiency. The elliptical tube design allows for closer tube spacing, resulting in greater surface area per plan area than round-tube coil designs. In addition, the revolutionary elliptical design utilizes elliptical spiral fin coil technology and has lower resistance to airflow than typical finned coil designs. This permits greater water loading, making the new elliptical coil the most efficient coil design available on the market. The coils are manufactured from high quality steel tubing following the most stringent quality control procedures. Each circuit is inspected to ensure the material quality and then tested before being assembled into a coil. Finally, the assembled coil is pneumatically tested at the appropriate pressure under water to ensure it is leak free.
