At Qingdao Conqinphi Environmental Technology Group Co., Ltd., we specialize in high-performance heat exchange solutions for demanding industrial environments. Our Plate Heat Exchanger for Industrial Wastewater Treatment is engineered with premium 304 stainless steel plates and rated for 1.0MPa operating pressure, delivering reliable and efficient cooling or heating for your wastewater processes. With over 300 skilled employees and a factory spanning 10,000–30,000 square meters, we combine advanced manufacturing capabilities with strict quality control to ensure each unit meets the highest standards of durability and thermal performance.
This heat exchanger is designed to handle aggressive fluids, suspended solids, and temperature fluctuations commonly found in industrial wastewater treatment. Its compact plate-and-frame construction maximizes heat transfer area while minimizing footprint, reducing energy consumption and operational costs. Whether you need to preheat incoming effluent, cool hot discharge, or maintain precise temperature for biological treatment, our unit offers a versatile and robust solution.
We understand that wastewater treatment plants face unique challenges such as fouling, corrosion, and pressure variations. That is why we have optimized the plate geometry and gasket materials to resist clogging and chemical attack, ensuring long service life with minimal maintenance. Every heat exchanger is pressure-tested before shipment, and we offer customization options for plate count, port size, and connection type to match your specific system requirements.

Why choose our plate heat exchanger for your wastewater treatment? The 304 stainless steel construction provides excellent resistance to pitting and crevice corrosion, especially in chloride-rich wastewater. The 1.0MPa rating allows integration into existing high-pressure systems without additional pressure reduction. Moreover, the modular design means you can easily add or remove plates to adapt to changing flow rates or temperature requirements, giving you flexibility for future expansion.
Our heat exchangers are widely used in industries such as municipal sewage treatment, food processing, chemical manufacturing, and textile dyeing. They can be used as sludge heaters, effluent coolers, or heat recovery units. The combination of high efficiency and low maintenance makes them a cost-effective choice for continuous operation.

Frequently Asked Questions
Q1: Can this heat exchanger handle wastewater with high solid content?
A: Yes, the plate design incorporates wide gaps and smooth flow channels that reduce clogging. For extremely high solids, we recommend using a strainer upstream and selecting a larger port size. Our gasket materials are also resistant to abrasion.
Q2: What is the typical lifespan of the 304 stainless steel plates?
A: With proper maintenance and in normal wastewater conditions (pH 4–10, chloride
Q3: Do you provide custom plate counts to match my exact heat load?
A: Absolutely. We can design the plate count from 10 to 500 plates per unit, adjusting the heat transfer area to meet your required duty. Our engineering team will calculate the optimal configuration based on your flow rates, temperatures, and pressure drops.
Q4: How do I clean the plates if fouling occurs?
A: The heat exchanger is designed for easy disassembly. You can remove the plates and clean them with a soft brush and mild detergent, or use a CIP (clean-in-place) system if installed. We provide cleaning instructions in the manual.
Q5: Is the 1.0MPa rating suitable for both cooling and heating applications?
A: Yes, the 1.0MPa design pressure is sufficient for most industrial water and steam heating applications up to 150°C. For higher pressure requirements, we can supply units rated up to 2.5MPa.
Q6: What certifications does your company hold for quality assurance?
A: We are certified under ISO9001, ISO14000, OHSAS18001, HACCP, and other standards. Our factory is audited regularly to ensure compliance. Each unit comes with a test certificate and material traceability.
Q7: What is the delivery time for a typical order?
A: For standard sizes, delivery is 15–25 working days. For fully customized units, it may take 30–45 days depending on complexity. We can expedite rush orders upon request.
Q8: Can you help with system integration and piping layout?
A: Yes, our technical support team can provide 3D drawings, piping recommendations, and even on-site installation supervision. We also offer commissioning services for large projects.
