Why is there increased pressure drop or reduced flow rate in my SPX APV ParaFlow?

  An increased pressure drop or reduced flow rate in your SPX Industrial Equipment may be caused by fouled plate surfaces or debris blocking the flow channels. To resolve this, you can open the heat exchanger and clean the plates. It is recommended to install screens or filters to prevent debris from entering the unit. Additionally, reverse flushing can help dislodge debris.

What to do if there is visible leakage from my SPX APV ParaFlow?
- Z
  Zachary WongAug 12, 2025
  If you observe visible leakage in your SPX Industrial Equipment, it could be due to several reasons. First, check if the operating pressure exceeds the heat exchanger's rating and reduce it if necessary. Second, ensure the heat exchanger is adequately tightened, increasing it in increments of .001 inch (0.025 mm) per plate, but not below the minimum dimensions. Also inspect the plates and gaskets for damage, dirt, cuts, cracks, or flat spots, replacing any defective parts. Finally, chemical attack on the gaskets may be the cause, in which case you should identify and eliminate the corrosive agent or change the gasket material.

How to improve reduced heat transfer in SPX APV ParaFlow Industrial Equipment?
- E
  eowensAug 20, 2025
  Reduced heat transfer in your SPX Industrial Equipment can stem from a few potential issues. Check that the inlet temperatures or flow rates match the original design conditions and correct them if needed. Another cause might be fouling on the plate surfaces, which can be resolved by opening the heat exchanger and cleaning the plates, or by circulating a suitable cleaning agent or reverse flushing without opening it. Freeze-up can also cause reduced heat transfer, so correcting temperatures or flow rates to design conditions is necessary.

What to do if there is cross-contamination in my SPX APV ParaFlow?
- L
  Lisa HarveyAug 28, 2025
  Cross-contamination in SPX Industrial Equipment can occur due to cracks or holes in the plates. Cracks may result from fatigue caused by pressure fluctuations, while holes can be due to corrosion. Inspect the plates, replace any defective ones, and identify and correct the source of pressure fluctuations or corrosion by eliminating the corrosive agent or changing the plate material.
