Since 1927 NRF has been a leading manufacturer of cooling products for the automotive market, industrial, rail and marine sector. In 1959 NRF invented the boxcooler, when they were asked to find a simple solution in order to keep the engines of river boats, which were cooled with surface water, free of fouling. Due to the success of this product, more and more vessels changed over to this type of cooling. Today, NRF is market leader in this field and beside the box cooler, NRF supplies shell and tube coolers, plate heat exchangers, and fin/fan coolers all over the world.
