Two-Phase Heat Exchangers

Stainless Steel Brazed Plate Heat Exchangers

Two-phase applications, such as evaporating and condensing, demand heat exchangers that excel in managing phase changes while maintaining reliability and efficiency. HeatX’s brazed plate heat exchangers, constructed from 316L stainless steel with copper, or stainless brazed are designed for these challenges. These units are optimized for refrigeration, heat pumps, chillers, evaporators, condensers, and other industrial applications, delivering superior corrosion resistance, high thermal efficiency, and precise temperature control.

These exchangers offer customizable configurations to meet specific pressure and temperature requirements, with working pressures up to 45 bar and temperatures ranging from -196 °C to 225 °C. The compact, leak-proof design minimizes pressure drop, reduces pumping costs, and ensures durability in high-pressure and extreme-temperature environments. These exchangers are not suitable for sanitary or marine applications but are ideal for HVAC, industrial cooling, and heat recovery systems.

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

Operations for two-phase heat exchangers involve key steps to maximize efficiency and performance:

• Fluid Preparation: Refrigerants or process fluids are conditioned to ensure compatibility with the exchanger, optimizing flow and composition for phase changes.
• Heat Transfer: Fluids undergoing phase change flow through alternating channels formed by brazed plates, with a heating or cooling medium in adjacent channels, facilitating efficient heat transfer.
• Temperature Control: Precise temperature regulation enhances phase change efficiency and prevents system inefficiencies.
• Pressure Management: Flexible designs accommodate high pressures, minimizing energy losses and ensuring reliable operation.
• Testing: Post-process testing confirms vapor or condensate quality, temperature accuracy, and compliance with industry standards.

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