Plate heat exchanger is an energy-efficient heat exchange equipment. It is widely used in food, chemical, power, HVAC and other industries with its high efficiency and compactness. Regular maintenance and care are essential to ensure its long-term stability. This guide will provide comprehensive plate and frame heat exchanger maintenance suggestions to help you extend the life of the equipment and optimize operating efficiency.
✅ Extend service life: Reduce corrosion, scaling and mechanical wear, and the equipment life can be extended by more than 30%.
✅ Save operating costs: Clean heat exchangers can reduce energy consumption by 10-20%.
✅ Ensure safety: Prevent leakage and abnormal pressure, and avoid the risk of medium mixing or environmental pollution.
📌 Recommended cleaning frequency:
Once every 6-12 months, depending on the working medium and running time.
| Issue | Possible Cause | Troubleshooting Suggestion |
|---|---|---|
| Reduced heat transfer efficiency | Fouling or blockage of plates | Disassemble plates and check for dirt or deposits |
| Increased pressure drop | Channel blockage or plate misalignment | Check inlet/outlet pressure and inspect plate arrangement |
| Leakage | Aging or damaged gaskets, poor sealing | Replace gaskets and re-tighten the unit |
| Cross-contamination | Plate perforation or corrosion | Open and inspect plates for cracks or corrosion holes |
✅ Frequent leakage, high maintenance cost
✅ Severe corrosion or perforation of the plate, can no longer be repaired
✅ Long-term low heat exchange efficiency, affecting production
✅ Old model, unable to adapt to new working conditions
Then, replacing a new and efficient plate heat exchanger may be a more economical and safer choice.
✅ Various models and specifications, adapted to the needs of different industries
✅ High-strength stainless steel or titanium plates, strong corrosion resistance
✅ Energy-saving design, heat exchange efficiency increased by 10-30%
✅ 100% compatible with genuine parts, non-standard customization
✅ Complete after-sales service and technical support
