Stainless Steel Brazed Plate Heat Exchangers

Dual-circuit heat exchangers are designed for applications requiring simultaneous heat transfer between multiple fluid streams, such as in advanced HVAC, refrigeration, and industrial systems. HeatX’s brazed plate 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 complex systems like chillers, heat pumps, and process cooling, ensuring precise temperature control and energy efficiency across multiple circuits.

Featuring advanced plate technologies, these exchangers support high-pressure operations up to 45 bar and temperatures from -196 °C to 225 °C. The compact, leak-proof design minimizes pressure drop, reduces energy consumption, and ensures durability in demanding dual-circuit environments. These exchangers are not suitable for sanitary or marine applications but are optimized for efficient heat transfer in sophisticated industrial and HVAC systems.

HeatX’s dual-circuit brazed plate heat exchangers provide a robust, energy-efficient solution for multi-circuit applications, ensuring low maintenance and long-term performance.

Operations for dual-circuit heat exchangers involve key steps to maximize efficiency and performance:

• Fluid Preparation: Multiple fluid streams (e.g., refrigerants or liquids) are conditioned to ensure compatibility with the exchanger, optimizing flow and composition for efficient heat transfer.
• Heat Transfer: Fluids flow through separate circuits within alternating channels formed by brazed plates, enabling simultaneous heat exchange with heating or cooling media, ensuring high efficiency.
• Temperature Control: Precise temperature regulation across multiple circuits optimizes system efficiency and maintains consistent performance.
• Pressure Management: Flexible designs handle varying pressures in each circuit, minimizing energy losses and ensuring reliable operation.
• Testing: Post-process testing verifies fluid quality, temperature accuracy, and compliance with industry standards for all circuits.

Each step leverages the precision and durability of HeatX’s brazed plate heat exchangers to ensure optimal performance in dual-circuit applications.
