bowman-cooling-for-data-centres
Bowman Cooling for Data Centres | Lancing Marine Lancing Marine supplies a performance-optimised range of Bowman shell & tube heat exchangers for use in liquid-cooled data centre systems — including CDUs, immersion tanks, rear-door systems, and mobile or marine edge enclosures.
With rack power densities now exceeding 80–100 kW, air cooling is no longer scalable. Bowman’s titanium-core exchangers, trusted in marine and industrial settings, are now enabling robust and future-ready cooling for hyperscale, AI/HPC, and modular data environments.
Overview: How Bowman Exchangers Work
Titanium-core Bowman heat exchangers for next-gen data centre cooling. Designed for immersion, CDU, edge, and marine deployments with full fluid compatibility.
- Each unit includes:
- Shell:
- Marine-grade aluminium for low weight & corrosion resistance
- Tubes: Grade 2 Titanium — chemically resistant, high performance
- End Covers & Plates: Aluminium or stainless, flange-ready options
Applications
- Immersion cooling tanks
- Direct-to-chip CDUs
- Rear-door retrofits
- Marine/edge mobile deployments

Maintenance & Service Recommendations
Proper maintenance ensures long-term performance of Bowman titanium tube-stack heat exchangers in high-duty data centre cooling systems.
- Water Quality: Cooling water (or fluid) must be filtered and free of particulates, biological contaminants, or metallic debris. Poor-quality fluid can accelerate wear and corrosion, even on titanium cores.
- Flow Rate Specification: Ensure flow rates remain within the heat exchanger’s rated capacity. Low or restricted flow can lead to thermal inefficiencies or hotspots, especially in direct-to-chip loops.
- Tube Stack Protection: Bowman titanium stacks are resistant to most corrosion and chemical attack — but exposure to improperly treated water or unfiltered glycol mixes may still result in deposits or fouling over time.
- Annual Inspection: It is recommended to inspect the exchanger every 12 months. This includes:
- Disassembly of end covers
- Checking and replacing O‑ring seals (as required)
- Cleaning the tube bundle with non-abrasive agents
- Visual inspection for fluid ingress or surface scaling
- O‑Ring Replacement: All Bowman exchangers use field-replaceable sealing kits. Always use OEM-supplied spares to maintain chemical and pressure compatibility.
Service kits and replacement tube stacks are available on request. For marine or edge deployments, quarterly checks may be advisable due to higher vibration or fluid exposure risk.
