Stainless Steel Brazed Plate Heat Exchangers

CO2 refrigeration and heat pump systems, utilizing carbon dioxide as an environmentally friendly refrigerant, require heat exchangers capable of handling high pressures and phase changes. HeatX’s brazed plate heat exchangers, constructed from 316L stainless steel with copper or stainless steel brazing, are designed for these demands, offering superior corrosion resistance and high thermal efficiency. These units are ideal for CO2-based refrigeration, heat pumps, and industrial cooling applications, ensuring precise temperature control and energy efficiency.

Featuring advanced plate technologies, these exchangers support high-pressure operations up to 45 bar and temperatures from -196 °C to 200 °C. The compact, leak-proof design minimizes pressure drop, reduces energy consumption, and ensures durability in demanding CO2 environments. These exchangers are not suitable for sanitary or marine applications but are optimized for efficient heat transfer in CO2 refrigeration and heat pump systems.

HeatX’s brazed plate heat exchangers provide a robust, energy-efficient solution for CO2 applications, ensuring low maintenance and long-term performance.

Operations for CO2 heat exchangers involve key steps to maximize efficiency and performance:

• Refrigerant Preparation: CO2 refrigerant is conditioned to ensure compatibility with the exchanger, optimizing flow and composition for efficient heat transfer.
• Heat Transfer: CO2 undergoing phase changes (e.g., evaporation or condensation) flows through alternating channels formed by brazed plates, with a heating or cooling medium in adjacent channels, ensuring efficient heat exchange.
• Temperature Control: Precise temperature regulation optimizes CO2 cycle efficiency and prevents system inefficiencies.
• Pressure Management: Flexible designs handle the high pressures of CO2 systems, minimizing energy losses and ensuring reliable operation.
• Testing: Post-process testing verifies CO2 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 CO2 applications.
