Reconditioning intervals depend on fluids, pressures, temperatures and the age of the equipment. But is this really creating a cost-efficient maintenance system? Proactive Maintenance for Plate Heat Exchangers Investment in this type of monitoring equipment may be restricted due to budgetary constraints or not be considered in an effort to cut cost. Monitoring equipment in the form of pressure and temperature gauges used to detect wear and stress on the unit can help to plan maintenance on all affected units. When pressure drop rises and exceeds original design or when loss of heat transfer occurs and the unit does not cool or heat as designed or specified, maintenance may be required. The owner of a plate heat exchanger need not wait for these visible signs of disrepair and failure before scheduling maintenance for a unit. Relying on a systematic check alone for leaks and damage is reactive in nature and can limit the effectiveness of a maintenance strategy. Providing maintenance at the point where such obvious errors occur is a far-too-common practice among industries that use plate heat exchangers. Visual checks tell when fouling or plugging occurs on the plate surfaces or when gaskets fail due to temperature excursions or compression set. Failures can be detected easily by anyone through visible leaks from gaskets to the atmosphere or cross-contamination between fluids through cracks in the plates in a regular check of the equipment.

It does not take a process heating professional to recognize when maintenance is required on a plate heat exchanger. Furthermore, if it is necessary to restore a unit to the original as-built design parameters or redesign based on new criteria, maintenance could be needed. While heating will cause the most stress on a plate heat exchanger, it is not necessarily true that heating will require more or less maintenance than a cooling system. Unscheduled production stops are costly and annoying. The plate heat exchanger must be allowed to maximize its efficiency as it originally was designed for either heating or cooling at specified pressure drops.

There are many reasons to schedule regular maintenance. Why Provide Maintenance for Plate Heat Exchangers? The plate pack is assembled between two pressure-retaining frames compressed with tightening bolts. Just what is a plate heat exchanger and why, when and how does one provide maintenance for it?Ī plate heat exchanger is a pack of thin, corrugated metal plates made from any stainless steel or exotic metals with ports for the passage of two fluids between which the heat transfer will occur. The purpose of this article is to look closely at the methods for maintaining a plate heat exchanger - sometimes referred to as a plate-and-frame heat exchanger or PHE - so that it runs as efficiently as possible for as long as possible. The hard questions come down to a simple strategy choice: Is your business not just reactive but proactive in its response to maintenance issues? A reactive approach is the most popular method that most manufacturing businesses use to save money short-term a proactive approach is forward-looking and prepares the business for eventual equipment failure and solving errors before they can affect production downtime or cash flow. It is not just spending money on maintenance that leads to effective productivity it is spending money wisely. This is not necessarily an either/or proposition: It is more of a good balancing act with a look toward the best methods of maintenance to garner the greatest equipment productivity. The challenge comes from knowing when to spend on maintenance efforts with a look toward a reasonable return on that investment and when maintenance can be effective through lower-cost methods.
