For optimal manufacturing productivity plate heat exchanger maintenance is a necessary part of your business strategy. Properly maintaining your facility’s heat exchangers can save your company tens of thousands of pounds in energy, downtime and repairs. A good maintenance and repair program for heat exchangers is always in the best interest of your business.
What is a plate heat exchanger?
A plate heat exchanger is a piece of equipment used to transfer thermal energy from one fluid to another. Both fluids are completely separated by the heat exchanger, the fluids never meet or mix. The fluids can be anything such as water, oil, refrigerant, etc. The fluids must be at different temperatures to transfer heat and heat always flows from hot to cold.
When it comes to heat exchangers, each one has its own specific protocol for cleaning, maintenance and troubleshooting; and there are many different problems that can occur. That’s why a planned heat exchanger maintenance procedure is best practice. Over time, sediment and grime can build up on plates or tubes and reduce efficiency. Corroded gaskets, uneven plate pack clamping, pressure losses, blockage and fouling are all issues that can eventually disrupt your system’s heat exchanger.
Why provide maintenance?
There are many reasons to schedule regular maintenance and heat exchanger chemical cleaning. Depending upon what fluids are being used in the heat exchanger, it is likely that the performance quality of the heat exchanger will decline over time. This deterioration in performance is typically due to the buildup of scale, sediment and grime on the plates. Fouling of the heat exchanger leads to a decrease in thermal performance, an increase in pressure drop across the exchanger and possibly a reduction in the flow through the exchanger.
Fortunately, PHE’s can be easily maintained, and problems can be easily identified. Planned heat exchanger maintenance is essential, and should be carried out at six-month intervals, even if the PHE appears to be functioning well.
It’s in your company’s best interest for the heat exchange to be performing at maximum efficiency and doing the job it has been designed to do. Unscheduled production stops are not only inconvenient but also very costly. Heating can often cause more stress on a plate heat exchanger, but the cooling system also needs regular maintenance.
Plate heat exchanger maintenance
If you’re looking for professional plate heat exchanger maintenance then we can help. At Heatxforce our planned maintenance inspections involve a visual check to spot any obvious signs of leakage. If no leakage is detected, then the gap between the outside pressure plates is measured to check that the plate pack is tightened to specification, that the carrying and guide bars are lubricated, and that the PHE gaskets have no obvious damage. Our specialists will then check the pressure drop to ensure that it is within expected limits, by recording pressure gauge readings on each side of the PHE.
