Welcome to Qingdao Conqinphi Environmental Technology Group Co., Ltd. Since our founding in 2015, we have dedicated ourselves to manufacturing high-quality heat exchange solutions. Our Semi-Welded Plate Frame Heat Exchanger with a flow rate of 20-200 L/min and durable EPDM rubber gaskets represents the perfect balance of efficiency, reliability, and customization. Designed for demanding industrial environments, this heat exchanger offers superior thermal performance while minimizing maintenance downtime.

Key Features & Benefits

  • Semi-Welded Construction: The plate pairs are laser-welded, eliminating the need for gaskets between certain plates, which reduces leak points and allows the unit to handle higher pressures and temperatures compared to fully gasketed designs.
  • EPDM Rubber Gaskets: High-quality EPDM gaskets are resistant to a wide range of chemicals, hot water, steam, and moderate temperatures, making them ideal for applications like HVAC, food processing, and industrial cooling.
  • Flow Rate Range 20-200 L/min: Covers a versatile range of low to medium flow capacities, suitable for small to medium-sized processes. The compact design saves valuable floor space while delivering excellent heat transfer efficiency.
  • Corrosion-Resistant Plates: Standard plate material is stainless steel (AISI 304 or 316), with options for titanium, Hastelloy, or other alloys upon request to match your specific fluid chemistry.
  • Easy Maintenance: The frame design allows quick access to the plate pack for cleaning, inspection, or replacement. Semi-welded channels reduce the number of gaskets to monitor, simplifying upkeep.
  • Customizable Configuration: We offer various frame lengths, port sizes, and connection types (flanged or threaded) to integrate seamlessly with your existing system.
  • High Thermal Efficiency: Counter-current flow design and specially pressed plate patterns maximize turbulence, enhancing the heat transfer coefficient while minimizing fouling.

Why Choose Our Semi-Welded Heat Exchanger?

  • Reduced Leak Risk: The semi-welded design eliminates half of the gaskets, significantly lowering the chance of cross-contamination and external leakage. This is especially critical in food, pharmaceutical, and chemical applications.
  • Higher Pressure & Temperature Capabilities: Welded plate pairs allow operation at elevated pressures and temperatures that would damage conventional gasketed plate heat exchangers.
  • Space & Weight Efficiency: Compared to shell-and-tube exchangers, our unit offers 3-5 times higher thermal efficiency in a much smaller footprint, reducing installation and structural costs.
  • Flexible Capacity: The flow range of 20-200 L/min covers many small to medium processes. Need different capacity? Our engineers can adjust the plate count, frame size, and port diameter to match your exact requirements.
  • Cost-Effective Maintenance: Only the gaskets on the non-welded side need periodic replacement. The welded channels rarely require service, lowering total cost of ownership.

Typical Applications

Industry Use Case
HVAC District heating, chiller systems, heat recovery
Food & Beverage Pasteurization, CIP heating/cooling, dairy processing
Chemical Processing Solvent heating, reactor temperature control
Pharmaceutical Water for injection (WFI) cooling, biotech processes
Oil & Gas Lube oil cooling, sample cooling

Frequently Asked Questions (FAQ)

  1. Q: What is the main advantage of a semi-welded plate heat exchanger over a fully gasketed one?
    A: Semi-welded designs eliminate about half of the gaskets, reducing leak points and allowing higher operating pressures and temperatures. They also minimize the risk of cross-contamination between media, making them ideal for aggressive or hygienic applications.
  2. Q: Can the EPDM gaskets withstand steam sterilization?
    A: Standard EPDM is suitable for continuous service up to 150°C and short-term exposure up to 180°C. For steam sterilization cycles (SIP), we recommend consulting our engineers for gasket material selection to ensure longevity.
  3. Q: How often do I need to replace the gaskets?
    A: Under normal operating conditions (clean fluids, moderate temperatures), EPDM gaskets can last 3-5 years. Harsh chemicals or frequent thermal cycling may reduce this life. Regular inspection is recommended.
  4. Q: What plate materials are available for corrosive fluids?
    A: We offer stainless steel 304, 316L, titanium, Hastelloy C276, and other alloys. Our sales team can help you select the optimal material based on your fluid analysis.
  5. Q: Can I get a heat exchanger with a flow rate outside the 20-200 L/min range?
    A: Yes, the unit is customizable. We can adjust the plate count, port size, and frame length to achieve higher or lower flow rates. Contact us with your parameters for a tailored solution.
  6. Q: How do I clean the heat exchanger?
    A: Cleaning can be done by circulating a suitable cleaning solution through the unit (CIP) or by opening the frame and manually cleaning the plates. The semi-welded design allows full access to both channels.
  7. Q: Does your company provide technical support for installation?
    A: Yes, we provide detailed installation manuals, and upon request, we can offer remote or on-site commissioning support. Our technical team is available during business hours.
  8. Q: What certifications does your factory hold?
    A: Qingdao Conqinphi is certified under ISO9001, ISO14000, OHSAS18001, SA8000, and others (HACCP, TL900, QS9000). This ensures consistent quality and responsible manufacturing processes.
