Bowman Header Tank Heat Exchangers
Bowman Header Tank heat exchangers are engineered for cooling marine propulsion and stationary land-based engines where traditional air cooling is unavailable or inappropriate. Offering a compact cooling alternative to air blast radiators, they consistently maintain correct engine operating temperatures while optimizing engine packaging space.
Key Benefits
- Unique Design & Quiet Zone
- Features a unique 'quiet zone' design with an integrated de-aeration system and a pressurized filler cap to maximize thermal performance.
- Reliable Operation
- The larger reservoir area located above the tube stack eliminates potential air pockets or air locks within the coolant stream, dramatically increasing structural operational reliability.
- Fully Floating Tubestack
- The fully floating design allows free expansion and contraction of the tubestack components within the cast body, significantly minimizing thermal stress and extending operational longevity.
- Simple to Maintain
- Easily removable tubestack units and end covers make routine cleaning, visual inspections, and field maintenance straightforward.
- Versatile & Wide Range
- Available in comprehensive configuration pass-options (single, double, or triple pass configurations) to suit diverse raw water flow rates and environmental conditions.
Key Features & Guidelines
- Flexible Applications: Tailored variants to process salt water, fresh water, or mineral-rich contaminated cooling streams safely.
- Mounting Rule: Must always be securely mounted above the engine's cylinder head level.
- Self-Venting Assembly: Design allows the engine circuit to remain fully self-venting on initial system filling.
- Thermostat Recommendation: A bypass-type thermostat should be deployed to ensure correct flow configuration when the engine is running cold; standard automotive type fill-interruption thermostats are not recommended.
Tubestack & Enclosure Materials
- Premium Cupro-Nickel Tube Stacks (Standard for land-based and marine variations)
- Cast Iron End Covers (Standard on land-based models)
- Corrosion-Resistant End Covers (Standard on marine specification models)
- High-grade Cast Outer Shell Body
Seals & Pressure Infrastructure
- Nitrile 'O' Ring Seals
- Pressurized Filler Cap Assembly (70 kPa / 50 kPa based on sizing model)
- Integrated De-aeration Reservoir Architecture
Jacket Water Connection Kits
- Composite Hose Adaptors (Standard on EH 100/200, FH 100/200/300/400 units)
- Cast Aluminium Hose Adaptors (Standard on GH 200/300/400 units)
- Two Blank Counter Flange Plates (Standard on heavy-duty KH, JH, and PH units)
Material Alternatives
- Titanium Tube Stacks: Ultimate corrosion protection with a 10-year guarantee against aggressive water conditions.
- Copper Tube Stacks: Cost-effective option for clean mains water/fire pump applications (Add suffix 'TC').
Safety Monitoring & Connections
- Automatic Murphy Level Switch (Available for KH, JH, PH, and select GH models to safely alert low water levels)
- Specialized Blank Counter Flange Plates (Optional swap-out for EH, FH, or GH units instead of standard hose adaptors)
