The Impact of Plate Heat Exchanger Leaks
A leaking plate heat exchanger (PHE) can lead to system downtime, energy inefficiency and potential contamination. Identifying the root cause quickly is the key to minimising costs and disruptions.
Whether it’s a small or large leak, here is everything you need to know about PHE leakage and how to stop and prevent it.
Common Reasons for Plate Heat Exchanger Leaks
If you’ve spotted a leak, its usually down to one of these culprits:
- Gasket Failure: Over time, gaskets can harden, perish or lose their elasticity. Once the seal is compromised, fluid will escape from the plate pack.
- Pressure Spikes: Sudden surges in pressure can move the plates, momentarily breaking the seal and causing a leak or permanently deforming the gaskets.
- Corrosion: If the fluids being used are too aggressive for the plate material small holes can form, leading to internal cross-contamination.
- Improper Tightening: If the plate pack isn’t tightened to the manufacturer’s specific instructions the gaskets won’t be compressed enough to create a seal. On the other hand, over-tightening can crush and damage the gaskets.
- Temperature Fluctuations: Rapid temperature fluctuations cause the metal plates to expand and contract too quickly, which can shift the gaskets out of place.
- Operating Outside Design Parameters: Many older PHEs were designed for specific high temperatures. If you’ve upgraded to modern condensing boilers that run at lower temperatures, the plate pack may no longer perform efficiently.
Need technical support to pinpoint the issue?
If you’re struggling to pinpoint the cause of the leak, contact our technical support team. We can help identify the exact issue and ensure you select the correct replacement parts.
How to Prevent Heat Exchanger Leaks
Prevention is always more cost-effective than reactive repairs, especially when you factor in the price of unscheduled downtime and operational disruptions. To extend the lifespan of your equipment and prevent issues, follow these best practices:
- Schedule Regular Servicing: Routine inspections allow you to catch brittle gaskets or early signs of corrosion.
- Choose Correct Materials and Fluids: Ensure your gaskets and plate materials are compatible with the fluids in your system.
Stick to Design Parameters: It is essential that your plant operates within the specific parameters your PHE was originally built for. - Implement Regular Cleaning: Dirt, debris and scale build-up can cause erosion. Regular cleaning maintains the condition of the plates.
