Hey there! If you’re working with gasketed plate heat exchangers (GPHEs), you know how efficient and space-saving they are. But like all systems, they need some TLC. Let's walk through the usual hiccups—leaks, blockages, and more—and I’ll show you how Aidear’s modular GPHEs make troubleshooting smoother than ever.
GPHEs offer excellent thermal performance, but that efficiency depends on healthy seals, clean plates, and tight assembly. Skipping maintenance? That’s like skipping oil changes—eventually, your system starts to drag, leak, or even fall apart.
Gaskets age—they dried out, swell from chemicals, or crack over time, leading to leaks that compromise performance.
Scaling from hard water, sediment, or process residue can clog channels, messing up heat transfer and pushing up pressure drop.
Metal plates suffer in aggressive environments—especially if cleaning solutions or chemicals eat away at the surface.
Improper tightening can warp plates or let gaps open—causing bypass flow, reduced efficiency, or even fluid mixing.
Repeated temperature swings can stress metal plates, eventually leading to hairline cracks and thermal breakdown.
Watch for sneaky signs: unexpected pressure rise, stagnant temperatures, or increased energy use—early indicators something’s off.
Check gasket surfaces and tighten bolts evenly. Scan for puddles, rust, or odd noises—sometimes a quick visual fix goes a long way.
Inspect every gasket sticker during a shutdown. Choose materials like EPDM, FKM, or PTFE based on heat, chemicals, and cleanability.
Match gasket to application—petroleum use NBR, steam needs EPDM, or aggressive chemicals go with FKM. Right material = fewer surprises.
Drain, disassemble, and clean with a neutral cleaner. Rinse thoroughly. Stuck on debris? Gentle soaking helps—but no abrasive scrubbing!
Press plates back in parallel and tighten in a cross pattern using proper torque to ensure even compression.
Slot plates in correct orientation. Use spacing tools, keep panels flat, and retorque in sequence for a leak-free seal.
Set maintenance intervals based on your fluid type and fouling risk. Track pressure deltas to catch issues early.
Install filters or better water treatment upstream—cleaner inputs mean less wear and longer uptime.
Train staff on routine checks and keep logs of pressure, temp, inspections, and replacements—history guides smarter maintenance.
Aidear GPHEs are like Lego blocks—plates slide in and out easily, making gasket changes and cleaning fast.
From food-grade EPDM to aggressive FKM, Aidear offers proper gaskets matched to your application and can ship parts globally fast.
Stuck on a maintenance question? Aidear supports with specs, troubleshooting tips, and service support worldwide.
Plate heat exchangers are powerhouses of efficiency—but only as long as they’re well-maintained. Leaks, clogs, worn gaskets—they’re all fixable with the right steps. And thanks to Aidear’s thoughtfully designed GPHEs, maintenance routines are smoother, cleaner, and less downtime-heavy.
Q1: How often should I inspect the gaskets?
Every 6 to 12 months, or sooner if your system uses aggressive chemistries or sees frequent thermal cycling.
Q2: Can I clean while still in place?
Yes—mild CIP solutions are often sufficient. Just verify compatibility with gasket materials.
Q3: What gasket fails first?
Often the ones exposed to high-temperature or acidic streams. Preemptive checks help avoid premature failure.
Q4: Does adding plates weaken gasket seals?
Only if improperly torqued. Aidear’s guidelines help maintain seal uniformity post-expansion.
Q5: Can Aidear help me choose right replacement parts?
Of course—they'll match gasket sets and plates based on your model and process requirements.
