Box Coolers

Service for Shell & Tube Heat Exchangers

The Kelvion box coolers are robust and built to last, but the anti-corrosion coatings may degrade over time. This can lead to a buildup of unwanted biological organisms, such as seaweed, algae and bacteria, that will restrict the flow and in turn lowers the thermal performance of the cooler – which affects the operation of equipment connected to the box coolers. The Kelvion refurbishment program will ensure a long service life and high availability. The Service includes sea chest inspections, cleaning, recoating and repairs to keep box coolers running efficiently.

Cleaning & recoating of box coolers

While measures to prevent industrial and marine pollution are good news for the environment, they have spurred biological growth which, in turn, has increased the risk of a buildup of unwanted organisms in on-board equipment. Kelvion box coolers are designed to require low maintenance and are less sensitive to fouling. The anti-corrosion coatings will however eventually degrade, this can lead to an increase of biological growth that will clog up the equipment and restrict the proper functioning of the box cooler. By cleaning and recoating the coolers, we can restore the anti-corrosion properties and extend the operational life of the box cooler and the ship’s equipment.
