The Brazed Plate Heat Exchanger is a new type of high-efficiency heat transfer equipment formed by stacking multiple corrugated metal plates and brazing them under high temperature. Unlike traditional shell-and-tube heat exchangers, our brazed plate heat exchanger eliminates the need for gaskets and frames. The working medium flows through narrow, tortuous channels created by adjacent plates, transferring heat through the separated plates. This design results in a heat transfer coefficient 2 to 4 times higher than conventional tube heat exchangers, offering exceptional thermal efficiency and energy savings.
High Heat Transfer Efficiency: With a typical K value of 3000-6000 W/m²·℃, our heat exchanger provides superior thermal performance, significantly reducing energy consumption.
Compact & Space-Saving: The brazed design without gaskets makes the unit extremely compact, saving valuable installation space.
Excellent Durability: Utilizing imported stainless steel plates (thickness 0.5-0.8mm) and advanced brazing technology, the unit offers high strength and resistance to extreme temperatures (up to 170°C / 338°F) and pressures (1.0MPa, 1.6MPa, and 2.5MPa).
Self-Cleaning Effect: The corrugated plate design creates turbulent flow, which helps prevent fouling, reduces thermal resistance, and extends maintenance intervals.
Versatile & Customizable: We offer multiple series (BR, BBR, KnBR, KbBR, BRH) and a wide range of corrosion-resistant materials to meet diverse application needs.
HVAC & Refrigeration: Chillers, heat pumps, condensers, evaporators, district heating.
Chemical & Petrochemical: Process heating/cooling, solvent recovery, resin cooling.
Power & Energy: Transformer oil cooling, generator bearing cooling, waste heat recovery.
Marine & Offshore: Engine cooling, hydraulic oil cooling, seawater cooling systems.
Food & Beverage: Pasteurization, sterilization, product heating/cooling.
Metallurgy & Machinery: Quenching fluid cooling, lubricating oil cooling for rolling mills.
Pulp & Paper: Heat recovery in bleaching processes, liquor heating.
Q1: How does a brazed plate heat exchanger work?
A1: The heat exchanger consists of multiple corrugated metal plates stacked together. Hot and cold fluids flow through alternating, separate channels created by these plates. As the fluids pass each other, heat is transferred from the hot fluid to the cold fluid through the thin metal plates. The brazing material seals the channels, ensuring the two fluids never mix, while the corrugated plate design maximizes turbulence for highly efficient heat transfer.
Q2: What are the key selection parameters for sizing a brazed plate heat exchanger?
A2: To correctly size and select the right heat exchanger, you need to provide the following key parameters:
Heat duty (kW): The amount of energy to be transferred.
Flow rates (m³/h) on both the hot and cold sides.
Inlet and outlet temperatures for both fluid streams.
Allowable pressure drop for each side.
Fluid properties: Type of fluid, viscosity, specific heat, and any corrosive properties.
Providing these details allows us to recommend the most efficient and cost-effective model.
Q3: What materials are available for corrosive media? Can you handle seawater or acids?
A3: Yes. We offer a wide range of premium materials for the plates, including Stainless Steel (304, 316L, 254SMO), Duplex Steel (2205), Hastelloy, Industrial Pure Titanium (TA1), and Pure Nickel (N6). For example:
Seawater / Brine: Titanium or 254SMO are recommended for their excellent resistance to chloride-induced pitting and crevice corrosion.
Sulfuric / Phosphoric Acid: Hastelloy or high-grade stainless steel.
High-purity applications: 316L stainless steel.
Q4: What are the common causes of performance issues and how to prevent them?
A4: Common issues include corrosion, fouling/blockage, and pressure drop. Solutions include:
Corrosion: Select appropriate corrosion-resistant materials and control fluid pH.
Fouling: Install a strainer or filter upstream to prevent solid particles from entering the exchanger, and perform regular cleaning.
Leakage: Since our brazed plate heat exchangers are gasket-free, internal leakage is extremely rare and usually indicates a manufacturing defect. Our 100% factory leak testing ensures reliable sealing.
Q5: Do you support custom-made products? What is your lead time?
A5: Yes, we specialize in custom manufacturing. You can customize the model, material, port type/orientation, and even the number of plates to match your exact thermal and hydraulic needs. The lead time for custom products depends on the order quantity and specifications. Typically, it ranges from 15 to 30 days. Standard products are available from stock. Please contact our sales team for a precise quote based on your project.
Q6: What certifications and standards do your products comply with?
A6: Our brazed plate heat exchangers are manufactured in strict accordance with the national standard GB16409-1996. We can also provide products that meet international standards such as ASME, PED, or CE upon request. Our factory is committed to quality control and rigorous testing to ensure reliable performance.
