Manufactured in the UK, Bowman inline plate heat exchangers are designed for compact closed-loop thermal transfer within modern data centre and HPC cooling infrastructure.

Bowman UK manufactured brazed plate heat exchangers for AI liquid cooling and CDU applications

Quick Specification Summary

Bowman brazed plate heat exchangers are designed for efficient thermal transfer within compact liquid cooling systems used across modern AI, HPC and data centre infrastructure. Their inline compact design allows straightforward integration into CDU systems, rear door cooling, secondary chilled water loops and direct-to-chip cooling circuits where installation space and thermal efficiency are critical.

Manufactured in the UK by E.J. Bowman, these exchangers provide reliable closed-loop cooling performance with low internal volume, high heat transfer efficiency and compact installation dimensions. Available across multiple plate configurations and connection sizes, the range supports both small edge cooling systems and larger modular liquid cooling infrastructure.

Bowman Heat Exchanger Range

Bowman inline plate heat exchangers are available in both standard copper brazed and copper-free brazed constructions depending on coolant compatibility requirements and system chemistry. Standard copper brazed units are commonly used within conventional closed-loop water and glycol cooling systems, offering compact construction, efficient heat transfer and cost-effective performance for CDU systems, secondary cooling circuits and general liquid cooling applications.

Copper-free brazed variants are typically specified where the coolant or operating environment may be incompatible with copper, including certain deionised water systems, ethanol-containing fluids or specialised process coolants. In these applications, copper-free construction helps reduce material compatibility concerns and supports longer-term reliability within sensitive liquid cooling infrastructure.</p>

The Bowman inline brazed plate heat exchanger range is available across multiple physical sizes and plate counts to suit varying thermal duties, flow rates and installation footprints. Compact inline construction allows straightforward integration into CDU systems, secondary cooling loops, rack cooling systems and direct-to-chip liquid cooling infrastructure where installation space is limited.

Standard copper brazed units are commonly used within closed-loop water and glycol cooling systems, while copper-free brazed variants are available for applications where coolant chemistry or system compatibility requirements make copper unsuitable.

Notes:

1. Maximum working pressure: 6 bar.
2. Maximum working temperature: 185°C (110°C with water).
3. Ensure suitable pressure relief valve is fitted upstream.
4. Compact inline construction suitable for CDU and rack cooling systems.
