15 Heat exchangers The Laminova heat exchanger Laminova heat exchangers provide outstanding engine and transmission oil temperature control in the most severe conditions. From high performance racing cars to Paris-Dakar rally cars, you can rely on Laminova. Laminova heat exchangers are used as oil coolers to control engine and transmission oil temperatures, or for instance the temperature of the power steering system. Another application is as intercoolers in turbo and supercharged petrol and diesel engines. Laminova oil coolers are more efficient than the competition due to the unique patented core design. The finned exterior on the cooler core creates a larger surface area compared to that of traditional radiator style coolers. The heat exchangers offer both maximum heat transfer and low pressure drop, something not before possible. The Laminova heat exchangers are custom designed and we cooperate closely with designers and OEM-manufacturers world wide. The small and flexible package is used for both cooling and heating applications in many different motor vehicles. Laminova oil coolers are more efficient than the competition due to the unique patented core design. 15

18 Cooperation, professionalism and mutual respect The history of Svenska Elektromagneter Since it was founded in 1915, Svenska Elektromagneter SEM has played an active role in swedish industry. The SEM factory in Åmål delivered the very first ignition equipment to Thulinverken in Landskrona during World War I. The equipment was installed in the plane Tummelisa, which had its inaugural flight immediately following the war. Reliability and quality were decisive factors behind the purchase and Svenska Elektromagneter was at that time the only company able to meet the demanding criteria. SEM has retained its focus on electromagnetism and over long periods the company s knowledge and products have been unique not only in Sweden but worldwide. Precision and environmental concern SEM s original idea remains firm: We shall develop and manufacture products that, in an energy-effective manner, initiate, generate and transform power. Performance and technical precision have gradually been extended with environmental requirements. Within the company there is an intensive, ongoing process to develop technology that can make a positive contribution to the environment.
