As a manufacturer with over 25 years of experience in metal fabrication and thermal solutions, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Single Pass Brazed Plate Heat Exchanger 20 Plate, 3/4" NPT, 200°C Max. This compact yet powerful heat exchanger is designed for efficient heat transfer in demanding industrial applications. Our factory, established in 1998, has built a reputation for delivering robust and reliable equipment to clients across North America, South America, Europe, and Asia. With an annual export value exceeding US$5 million, we combine precision engineering with cost-effective manufacturing to offer you a high-performance solution for liquid heating and cooling.
The Single Pass design ensures that the fluid flows through the entire plate pack in one direction, maximizing temperature differential and thermal efficiency. The 20 plates are vacuum-brazed using copper or nickel filler, creating a solid, leak-proof unit that can withstand high pressures and temperatures up to 200°C. Each plate is made from 316L stainless steel, providing excellent corrosion resistance against water, glycol, oils, and many chemical solutions. The 3/4" NPT connections are standard in North America and compatible with most piping systems, making installation straightforward.
Below we provide a detailed breakdown of the technical specifications and performance characteristics of this heat exchanger. Please note that all values are based on typical operating conditions and can be customized upon request.

| Weight | Approx. 5.5 kg (12.1 lbs) |
Key Features & Benefits:
- High Thermal Efficiency: The counterflow design and brazed plate construction achieve heat transfer coefficients up to 3–5 times higher than shell-and-tube exchangers, reducing energy consumption.
- Compact Footprint: With only 20 plates, this unit occupies minimal space, ideal for retrofitting into existing systems or for use in tight machinery enclosures.
- Durable Construction: Vacuum brazing creates a monolithic structure without gaskets, eliminating leak paths and allowing operation at high temperatures and pressures.
- Easy Integration: Standard 3/4" NPT connections simplify installation with common pipe fittings; no special tools required.
- Versatile Application: Suitable for water heating, oil cooling, steam condensation, refrigeration, and many industrial processes where liquid-to-liquid heat exchange is needed.
- Customizable Options: We can adjust plate count, connection type, brazing material, and pressure rating to match your specific requirements.
Our Single Pass Brazed Plate Heat Exchanger is manufactured under strict quality control procedures. Each unit undergoes a helium leak test and a pressure test to ensure zero leakage. The 316L stainless steel plates provide excellent resistance to pitting and stress corrosion, extending the service life even in aggressive environments. The 3/4" NPT ports are threaded to ANSI standards, ensuring a secure connection. With a maximum temperature of 200°C, this exchanger can handle hot oil, steam, and high-temperature water applications safely.
For customers who require higher pressures or temperatures, we offer alternative designs with nickel brazing and thicker plates. Our engineering team can also provide custom dimensions and port configurations. Please contact us with your fluid properties, flow rates, and desired temperature changes to receive a tailored recommendation.
Frequently Asked Questions (FAQ)
- What fluids can be used with this heat exchanger? It is compatible with water, water-glycol mixtures, thermal oils, refrigerants, and many non-corrosive chemicals. For aggressive fluids, please verify material compatibility with our team.
- Can I use this exchanger for steam heating? Yes, it can handle steam up to 200°C. However, for condensing steam, proper drainage and venting are required to avoid water hammer.
- What is the maximum pressure drop across the unit? Pressure drop depends on flow rate and fluid viscosity. Typically, for water at 20 GPM, the pressure drop is around 0.5–1 bar. We can provide detailed calculations upon request.
- Is the 3/4" NPT connection male or female? It is female NPT (threaded), allowing you to connect male pipe nipples directly.
- How do I clean the heat exchanger if it fouls? Since this is a brazed unit, chemical cleaning is recommended. Flush with a suitable cleaning solution (e.g., mild acid for scale) followed by a thorough rinse. Avoid mechanical cleaning.
- Can I order a unit with different plate count? Yes, we offer from 10 to 100 plates. Please specify your required heat transfer area or performance parameters.
- What is the warranty period? We offer a standard 12-month warranty against manufacturing defects. Extended warranties are available upon request.
- Do you provide technical support for system design? Absolutely. Our team can assist with sizing, selection, and integration into your existing system. Just provide your process conditions.
With an annual export value of US$5–10 million, our factory serves customers in over 30 countries, including North America, Southeast Asia, Africa, and Europe. We ship from major ports such as Tianjin, Qingdao, Shanghai, and Foshan, ensuring reliable logistics. Our long-standing experience in metal fabrication since 1998 guarantees that each heat exchanger is built with precision and care. We invite you to place a trial order or request a sample to experience the quality firsthand.
