RSW chiller – VK

Type VK
Flooded Shell & Tube design for seawater and brackish water. Designed for halocarbons.

Shell
Made of seamless steeltube in quality St. 35 according to Det Norske Veritas requirements.

End plates
These are made of solid, stainless, acid resistant steel. The plates are welded to the shell.
The holes for the tubes are exactly made, with grooves to assure a safety tightening as tubes are rolled in.

The tubes for halocarbons are made of aluminium-brass in the well known alloy for seawater, 76% copper, 2% aluminium and 22% zinc. This alloy has prooved to have extremely high resistance against corrosion from seawater and brackish water.
The tubes are of “low fin” construction with external fins made from the tube itself. Outside surface then increases considerably, resulting in a high efficiency compact cooler. The tubes are rolled into the endplates, and are replaceable.
