Double Wall Heat Exchangers

Stainless Steel Brazed Plate Heat Exchangers

Double wall brazed plate heat exchangers are designed for fluid-to-fluid applications requiring enhanced safety to prevent cross-contamination between fluids. HeatX’s double wall heat exchangers, constructed from 316L stainless steel with copper or stainless steel brazing, offer superior corrosion resistance and high thermal efficiency. These units are ideal for HVAC, district heating, domestic hot water, and industrial applications where fluid separation is critical, ensuring precise temperature control and energy efficiency.

Featuring advanced plate technologies with double wall plate configurations, these exchangers support high-pressure operations up to 40 bar and temperatures from -196 °C to 225 °C. The compact, leak-proof design minimizes pressure drop, reduces pumping costs, and ensures durability in demanding environments. These exchangers are not suitable for sanitary or marine applications but are optimized for secure fluid-to-fluid heat transfer in industrial and HVAC systems.

HeatX’s double wall brazed plate heat exchangers provide a robust, energy-efficient solution for applications requiring fluid separation, ensuring low maintenance and long-term performance.

Operations for double wall heat exchangers involve key steps to maximize efficiency and safety:

• Fluid Preparation: Fluids are conditioned to ensure compatibility with the exchanger, optimizing flow and composition for efficient heat transfer while maintaining separation.
• Heat Transfer: Fluids flow through alternating channels formed by double wall brazed plates, ensuring efficient liquid-to-liquid heat exchange with a barrier to prevent mixing.
• Temperature Control: Precise temperature regulation optimizes system efficiency and maintains consistent heating or cooling performance.
• Pressure Management: Flexible designs handle varying pressures, minimizing energy losses and ensuring reliable operation.
• Testing: Post-process testing verifies fluid integrity, temperature accuracy, and compliance with industry standards, ensuring no cross-contamination.

Each step leverages the precision and durability of HeatX’s double wall brazed plate heat exchangers to ensure optimal performance and safety in fluid-to-fluid applications.
