Header Tank Heat Exchangers

Engine jacket water cooling for marine propulsion or stationary land-based engines.

Bowman Header Tank heat exchangers are designed to cool engine jacket water in applications where air cooling is either unavailable or inappropriate, due to the nature of the installation. They are also suited to applications where high ambient temperatures are experienced, offering a more efficient and quieter solution compared to air blast systems.

Product Benefits

  • Compact design Easily integrated with the engine
  • Easy product selection Provided quickly by our technical experts
  • Quiet operation Reduced noise when compared to air-cooled engines
  • Efficient range Designed for engines up to 1500 kW
  • Rapid delivery Extensive stockholding for fast response
  • Marine & land based versions Suitable for virtually any cooling fluid

Quiet Operation

The unique ‘quiet zone’ design has a special de-aeration feature, whilst the large reservoir area above the tube stack eliminates the problem of air pockets or air locks getting into the cooling system.

Marine and Land Versions

Originally designed for cooling marine engines / gen-sets with sea water, Bowman header tank heat exchangers are also ideally suited for land-based engines, where fresh water is used for cooling.

Comprehensive Range

Proven worldwide in applications as diverse as marine propulsion, CHP / co-generation, engine driven pumps and automotive engine testing on engines rated up to and in excess of 1 MW.

Titanium Tube Stacks

Titanium tube stacks are available as an option in place of cupronickel. The titanium materials have a 10-year guarantee and can operate at higher flow rates, compared to standard tube stacks.

Jacket Water Connection

Hose connectors are provided on the most popular models for easy connection to the engine cooling water circuit. Counter flange plates are provided on larger models.

Easy to Maintain

Simply by removing the end covers, the tube stack assembly can be easily withdrawn from the outer ‘shell’ for routine cleaning and maintenance procedures. A full range of replacement parts is also available.

Header Tank Heat Exchangers – Typical Performance and Dimensions

The following information offers a general guide to the performance and dimensions of our standard range of header tank heat exchangers. For more detailed information on additional configurations and specific applications, please download the product brochure. Computer aided selection software (CAS) is available to accurately select the correct heat exchanger specifically for your application.

Please contact us or your nearest stockist with the following information to receive a CAS selection:

  • Heat to be dissipated in kW
  • Engine water flow rate in l/min
  • Maximum engine water temperature in °C
  • Cooling water temperature in °C
  • Type of cooling water to be used (sea water, fresh water or contaminated water)
