Boxcoolers

Boxcoolers are efficient cooling systems designed for installation in all types of ships. Boxcoolers cools down the primary circuit using seawater. No water-filters, valves and extra seawater pumps are needed. The boxcoolers can be mounted longitudinal or transversal in the seachest.

Boxcoolers can be used in fresh-, brackish water and seawater. The boxcooler will be supplied as a package, complete with a steel welding frame, making drilling and tapping unnecessary. Boxcoolers has to be placed in a seachest. To optimize natural circulation and heat-transfer boxcoolers should be installed with a minimum of 150 mm of free space between the tubes and the inside wall of the seachest. Boxcoolers can be demounted if the topplate of the seachest is above the waterline. Even when the vessel is afloat.

Upon request the boxcoolers can be supplied with a test certificate of one of the well-known classification societies. For example ABS, Bureau Veritas, DNV-GL, Lloyds Register of Shipping, RINA, RMRS, RRR and various others upon request.

  • Boxcoolers
  • Heat exchangers / oilcoolers
  • Bottom-type coolers
  • Expansion tanks

Blokland Non Ferro formed an alliance with Cathelco, the world’s leading manufacturer of antifouling products, to develop a range of antifouling systems designed specifically to provide the highest level of efficiency.

Benefits

  • Uniform distribution of copper ions along the cooler housing for greater effectiveness.
  • The cathode plate guarantees a uniform wear pattern along the anode.
  • Systems designed to be renewed during the entrance to the dry dock.
  • Llalco can adapt the antifouling systems to adapt to any size or shape of the case cooler.

When operating in seawater, box coolers can be protected against biological fouling by an ICAF (Impressed Current Anti Fouling) system. There is an ICAF system of copper anodes and steel cathode plates that are placed in the closest place, directly below the Boxcooler. The anode is connected to an electrical control panel. The constant current will dissolve the copper in the seawater. Copper ions will create a hostile environment for biological fouling. The anode replacement intervals can be designed to coincide with the ship’s dry docking program or the service life of the box coolers up to a maximum of 5 years.
