As a reliable manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. specializes in producing high-performance heat transfer solutions. Our High Energy Efficiency Plate Heat Exchanger, DN50 Flange Connection, 304SS, 1.6MPa Industrial Grade is designed to meet demanding industrial requirements while maximizing thermal efficiency. With over 200 skilled employees and a modern factory spanning 10,000–30,000 square meters, we engineer every unit to deliver consistent performance and long-term durability.
This plate heat exchanger features 304 stainless steel plates that offer excellent corrosion resistance and high heat transfer coefficients. The DN50 flange connection ensures compatibility with standard piping systems and simplifies installation. Rated for 1.6 MPa operating pressure, it is suitable for a wide range of industrial processes, including HVAC, chemical processing, food & beverage, and oil & gas applications.
Key Features & Benefits:
- High Energy Efficiency: Patented corrugated plate design creates turbulent flow, achieving up to 90% heat recovery and reducing operational costs.
- 304 Stainless Steel Construction: Provides excellent resistance to rust, acids, and alkalis, ensuring long service life even in harsh environments.
- DN50 Flange Connection: Conforms to standard industrial flanges (PN16/Class 150), enabling easy integration into existing pipelines.
- Compact & Lightweight: Modular plate stack saves floor space compared to shell-and-tube exchangers, ideal for retrofit projects.
- Easy Maintenance: Gasketed design allows quick disassembly for cleaning, plate replacement, or capacity expansion without replacing the entire unit.
- Customizable Options: Number of plates, gasket materials (NBR, EPDM, Viton), and frame coatings available to match specific media and temperatures.

Frequently Asked Questions:
- Q: What is the maximum heat transfer capacity of this model? A: The capacity depends on the number of plates and flow rates. For a typical 50-plate unit with water-to-water application, it can handle up to 500 kW. Contact our sales team for a precise sizing calculation.
- Q: Can this heat exchanger be used with corrosive fluids? A: Yes, the 304SS plates offer good resistance to many corrosive media. However, for highly aggressive chemicals, we recommend upgrading to 316L or titanium plates (available upon request).
- Q: How do I clean the plates if fouling occurs? A: The gasketed design allows easy disassembly. Plates can be washed with a soft brush and mild detergent, or chemically cleaned. For CIP (clean-in-place) systems, we can provide optional cleaning connections.
- Q: Is the flange compatible with both PN16 and Class 150 standards? A: Yes, our DN50 flanges are drilled to match both PN16 (ISO) and Class 150 (ANSI) bolt patterns, ensuring broad compatibility.
- Q: What gasket materials are available? A: Standard is NBR (-20°C to 120°C). For higher temperatures or chemical resistance, we offer EPDM (up to 150°C) and Viton (up to 180°C). Please advise your operating conditions.
- Q: What is the warranty period? A: We provide a 12-month warranty from the date of shipment against manufacturing defects. Extended warranty options are available upon negotiation.
- Q: Do you offer custom plate patterns or sizes? A: Yes, we can adjust plate corrugation angles, thickness, and overall dimensions to optimize performance for your specific duty. Minimum order quantities apply.
- Q: How long does delivery take? A: Standard units with common plate quantities ship within 15–25 working days. Customized orders typically require 30–45 working days, depending on complexity.
