For over 80 years, Bowman has provided efficient cooling solutions to the marine industry. The quality and reliability of our heat exchangers is renowned worldwide.Bowman is now at the forefront of cooling technology, providing a range of high performance heat exchangers to suit the demands of electric and hybrid power systems. With battery technology constantly improving, electric powered propulsion systems of 100 kW and beyond are now increasing the range of electric marine propulsion. For such applications, cooling requirements can include the battery pack and on board charger, AC-DC converter, DC-DC converter, plus the electric drive motor itself. For hybrid power systems, there may be additional equipment to be cooled, such as the Hybrid Control Unit, the combined Electric Motor/Generator, plus engine powered generators. However, the amount of heat generated must be controlled to ensure safe and efficient operation at all times. With many Electric and Hybrid systems designed to operate with sea water temperatures up to 35ºC, the cooling system is vitally important and here Bowman can provide an efficient solution for virtually any application.
