Shell & tube heat exchangers for electric and hybrid marine

Efficient heat exchangers for cooling electric motors, battery packs, chargers, AC-DC converters, DC-DC converters, inverters and associated equipment for electric and hybrid marine propulsion and charging systems.

For over 80 years, Bowman has provided quality heat exchangers for the marine industry. Now as the industry seeks to lower CO2 emissions, Bowman is also providing cooling solutions for the new generation of electric and hybrid systems being developed to meet increasingly stringent emissions regulations.

Features

Efficient and Durable

Bowman heat exchangers are renowned for their high performance and long-life, even in the harshest operating conditions.

Industry Standard Materials

Only proven marine specification materials - such as titanium, cupronickel, aluminium, brass and composites - are used in Bowman marine heat exchangers.

Reliability

The precision-engineered, fully floating tube stack minimises thermal stress and is less affected by blockages compared to plate type units.

Titanium Range

Now available, a range of commercially attractive titanium heat exchangers that offer performance, durability and weight reduction.

Compatibility

Ideally suited for electric and hybrid marine applications, where coolant flow around the electrical components is often much lower than the sea water flow.

Simple to Maintain

Removable end covers enable the tube stack to be easily withdrawn from the outer shell, ensuring maintenance is simple and straightforward.

Specification

Shell and Tube Heat Marine Exchangers – Typical Performance and Dimensions

The following information offers a general guide to the performance and dimensions of our standard range of marine grade shell and tube heat exchangers.

For more detailed information on additional configurations, please download the product brochure, or contact our technical sales team on +44(0)121 359 5401, or email [email protected].

Easy Product Selection

Electric and hybrid systems are often designed to operate with sea water temperatures of 30 °C plus, making selecting the right heat exchanger critical. Whilst the tables below list typical performance examples at given temperatures and flow rates, they are intended as a general guide only.

However, by supplying the following information, we can provide a computer-aided product selection, to recommend the most appropriate heat exchanger for your requirements:

  • Coolant type and concentration
  • Heat to be dissipated in kW
  • Required coolant outlet temperature in °C
  • Coolant flow in l/min
  • Sea water temperature in °C
The image above is representative of the Shell and Tube Marine Heat Exchanger range from EC80 to RK600.

Note – Dimensions in the tables refer to standard three-pass, sea water heat exchangers. For part numbers and more detailed drawings, please download the brochure or contact the technical sales team.

Both tables include products that are suitable for cooling electrical propulsion systems and equipment with sea water but the first table includes heat exchangers with a cupronickel tube stack and the second table includes part numbers for heat exchangers fitted with titanium tube stacks.

Cupronickel heat exchangers are rated to a maximum pressure of 20 bar on the coolant side and 16 bar on the sea / fresh water side of the cooler at a maximum temperature of 110 °C. Titanium heat exchangers are rated to 4 bar pressure at a maximum temperature of 95 °C.

Larger heat exchangers are also available for higher heat loads. Download the brochures or contact our sales team for more information.
