Closed Circuit Cooling Towers

SPL’s exclusive condensing coils is manufactured at SPL from high quality steel tubing following the most stringent quality control procedures. Each circuit is inspected to assure the highest material quality.

All SPL coils are formed in one continuous piece using a unique automatic coil production line, this process limits welding slag, increases production efficiency and factory lead times. The coils are hydrostatically tested 3 times during the manufacturing process to 2.5Mpa to ensure they are leak free.

To protect the coil against corrosion, coils are placed in a heavy steel frame and then the entire assembly is dipped in molten zinc (hot-dip galvanized) at a temp of 427˚C. The tubes are pitched in the direction of fluid flow to provide good liquid drainage.
