INDEX WHAT IS A BOX COOLER MULTI CIRCUIT BOX COOLER ANTIFOULING SYSTEMS ICAF SYSTEM ULTRASONIC ANTIFOULING SPARE PARTS CLASSIFICATION SOCIETIES

A BIT OF HISTORY... IN 1959 NRF WAS TASKED WITH FINDING A SIMPLE SOLUTION IN ORDER TO KEEP THE ENGINES OF RIVER BOATS, WHICH WERE COOLED WITH SURFACE WATER, FREE OF FOULING. THAT IS HOW NRF CAME UP WITH THE BOX COOLER. DUE TO THE SUCCESS OF THIS PRODUCT, MORE AND MORE VESSELS CHANGED OVER TO THIS TYPE OF COOLING. WHAT IS A BOX COOLER The box cooler is an efficient cooling system, designed for efficient installation on small and medium sized vessels. The box cooler consists out of a U-shaped tube bundle that is fitted in the sea chest of the ship. The compact design ensures an efficient and...

NRF box coolers can be modified to adapt to different space and cooling requirements. Multiple sizes are available upon request. Box coolers have many cooling capabilities. Different types of vessels could benefit from using a box cooler, for example: dredgers, ferries, still standing generators, tugboats, fishing boats, takers, cargo freighters, etc. MANUFACTURING MATERIALS AND COATINGS Cover : Carbon Steel Gaskets : CR/SBR; (CR>=20%) Weldingframe : Carbon Steel Tubesheet : Muntz metal Tube bundle: • Aluminium Brass Ø 11 * 0.8 or 1 mm tube bundle made out of Aluminium/Brass are often used...

STANDARD TOP-DOWN BOX COOLER The “Top-Down” installation of the box cooler is the most common application and our best seller. Top-down design is the original based installation from the inside of the engine room. It is mounted downwards through the top deck into the sea chest. NRF offers a coated version (for sea water application) and bare versions (for river going or inland application). For seagoing use, NRF can complete this box cooler with an ICAF (impressed current anti fouling) system. This anti fouling system prevents fouling in between the docking periods.

OUTSIDE MOUNTING BOX COOLER Depending on the ship, a larger box cooler might be needed which brings up the need of an assembly form where the cooler is not installed from within the engine room but from outside of the hull. The BottomBuild box cooler is the best solution for fully equipped engine rooms where transport of these coolers inside the engine room is not a viable option. Our Bottom-Build box cooler is designed for easy removing out of the sea chests in case of maintenance and inspection. This can be done whilst the ship is still afloat.

ADAPTED TO YOUR SPACE STEPPED BOX COOLER To maximize the possible cooling surface of a box cooler in a sea chest, the bundle must follow the shape of the hull as close as possible. This can be done by dividing the bundle is several sections, each with different length. ADVANTAGES: Available in Bottom-Build and Top-Build installations. Adapted to the exact shape of the sea chest. Ideal for sea chests with limited space. Can be adapted for multiple circuits with different heat exchange requirements. EXTENDED BOX COOLER To maximize the possible cooling surface of a box cooler in a sea chest,...

ADAPTED TO YOUR NEEDS MULTI CIRCUIT BOX COOLER For cooling separate water circuits, normally two or more box coolers are required. When the coolers are not too big, it is possible to combine the different circuits into one box cooler. This limits the space requirement of the box cooler. Extra measures have been taken into the construction to prevent intermixing of the different circuit. ADVANTAGES: Available in Bottom-Build and Top-Build installations. Space saving solution. Lower cost. Eliminated the need for two or more coolers in certain situations.

ANTIFOULING SYSTEMS FOR YOUR BOX COOLER

ICAF SYSTEM IMPRESSED CURRENT ANTI FOULING SYSTEM TOP-BUILD WITH ICAF SYSTEM BOTTOM-BUILD WITH ICAF SYSTEM The ICAF System is a highly effective anti-fouling system that can be installed on the box cooler. Highly reduces biological fouling thanks to the copper anodes mounted under the box cooler that slowly dissolve by receiving an electrical current from a power supply. This creates an environment in which biological marine growth will not develop and will just be flushed out back into the sea. The copper ridden environment is only active during a limited time as these ions fall back to...

ULTRASONIC ANTIFOULING The Ultrasonic system offers an effective solution for addressing marine biofouling, preventing potential overheating of ship engines that could lead to expensive emergency dry dockings. Its continuous operation eliminates the need for frequent inspections both onboard and underwater, thanks to the monitoring system. The working principle of ultrasonic marine growth prevention is straightforward: any object submerged in seawater that vibrates within the ultrasonic frequency range, with sufficient sound pressure, remains unfouled. Larvae of fouling organisms do not...

MAINTENANCE AND REPAIR PARTNERS In general, NRF box coolers are a maintenance free system. However, considering their long lifespan and given the different sailing areas and operating conditions, biofouling must be considered. The implementation of local and international control measures preventing pollution has resulted in a substantial reduction of toxic effluent from industry and marine traffic. This has greatly encouraged organic growth in rivers, estuaries and coastal waters, resulting in an increased trend of biofouling. SPARE PARTS NRF is the place to get box cooler parts. Besides...
