Profile: N R F (United Kingdom) Ltd. specializes in producing cooling systems. We provide radiators, radiator cores, air coolers, oil coolers, box coolers and air conditioning components. Serpentine radiator cores are characterised by their high cooling capacity in applications where there is relatively little installation space. We offer ten different fin systems, pipes and material thicknesses, both in aluminum and copper/brass. These radiator cores vary from the aluminum AS94 system with its high cooling capacity, to the copper/brass SW (square wave) systems with uncut fins that combine a good cooling capacity with resistance against contamination. We offer a wide choice of different types of compressor, with a fixed or variable stroke volume. From a piston compressor (up to 10 cylinders) to a compressor with rotating vanes or a helical compressor. The air coolers for trucks features intercooler that cools the air that enters the inlet manifold. The air contracts and more oxygen is forced into the combustion chambers.
