Service Support for Gasketed Plate Heat Exchangers

Gasketed plate heat exchangers provide efficient heating, cooling and heat recovery across many industrial applications. However, fouling, ageing gaskets, incorrect tightening, corrosion or changing process conditions may eventually affect their thermal performance and reliability.

Depending on the equipment and confirmed requirement, service support may cover:

• Preliminary equipment inspection

• Performance troubleshooting

• Plate cleaning

• Gasket inspection and replacement

• Plate-pack regasketing

• Plate inspection

• Leak investigation

• Frame and tightening-bolt inspection

• Spare-parts identification

• Genuine Alfa Laval plate and gasket enquiries

• Preventive-maintenance planning

• Reconditioning coordination

• Capacity and operating-condition review

• Heat exchanger replacement enquiries

The final service scope must be determined after reviewing the equipment identification, service history and present condition.

Signs That a Plate Heat Exchanger May Require Service

A gasketed plate heat exchanger should be assessed when operators notice:

• Reduced heating or cooling performance

• Increasing outlet-temperature deviation

• Higher pressure drop

• Reduced flow

• External leakage from the plate pack

• Suspected internal mixing of fluids

• Unusual gasket movement

• Frequent need for tightening

• Corrosion or visible plate damage

• Fouling or scale formation

• Uneven plate-pack alignment

• Performance below the original process requirement

These symptoms can have several causes. For example, reduced thermal performance may result from fouling, insufficient flow, changed inlet temperature or altered fluid properties. Troubleshooting should therefore examine the complete operating condition before recommending corrective work.

Plate Heat Exchanger Troubleshooting

Effective troubleshooting begins with verified process data. Customers should provide:

• Heat exchanger manufacturer and model

• Serial number

• Plate material

• Gasket material, if known

• Process and utility fluids

• Inlet and outlet temperatures

• Flow rates

• Operating pressures

• Current pressure drop

• Date of the last service

• Nature and location of any leakage

• Photographs of the unit and nameplate

• Description of recent process changes

Do not continue repeatedly tightening a leaking plate heat exchanger without checking the manufacturer’s specified plate-pack dimension. Excessive compression can damage plates and gaskets.

Plate Cleaning Services

Deposits on heat-transfer surfaces can restrict flow and reduce thermal performance. The correct cleaning method depends on the deposit, plate material, gasket material and process-fluid characteristics.

Possible approaches include:

Cleaning-in-Place

Cleaning-in-place may be considered when the deposits can be removed by circulating a compatible cleaning solution without opening the heat exchanger.

The cleaning chemical, concentration, temperature, circulation time and flushing procedure must be compatible with the plates and gaskets.

Manual Plate Cleaning

Where dismantling is appropriate, plates may be cleaned individually using suitable methods. Metal tools, aggressive abrasives and incompatible chemicals can scratch or damage the plates and should not be used.

Professional Reconditioning

Reconditioning may involve inspection, gasket removal, controlled cleaning, post-cleaning inspection, crack detection, regasketing and reassembly. The applicable procedure depends on the equipment condition and agreed service arrangement.

Cleaning should not begin until the nature of the deposit and compatibility of the proposed cleaning method have been reviewed.

Plate and Gasket Inspection

During inspection, attention may be given to:

• Plate deformation

• Cracks or pinholes

• Corrosion or erosion

• Damaged sealing grooves

• Fouling and scaling

• Incorrect plate sequence

• Ageing, hardened or swollen gaskets

• Gasket displacement

• Frame corrosion

• Damaged tightening bolts

• Incorrect plate-pack compression

A visual inspection alone may not reveal every plate defect. Where appropriate, specialised leak or crack-detection procedures may be required.

Gasket Replacement and Regasketing

Heat exchanger gaskets may gradually lose elasticity because of age, temperature, pressure, cleaning chemicals or incompatibility with the process fluid.

Regasketing normally requires:

1. Confirming the heat exchanger model and serial number

2. Identifying the correct gasket material

3. Removing old gaskets and residues

4. Cleaning and inspecting the gasket groove

5. Installing the correct replacement gaskets

6. Checking the plate sequence and orientation

7. Reassembling the plate pack correctly

8. Tightening to the specified dimension

9. Performing the applicable leak or pressure test

Gaskets should be selected for the actual fluids, temperatures and operating conditions—not merely by their colour or appearance.

Genuine Alfa Laval Spare Parts

Correct plates and gaskets are essential for maintaining the intended sealing arrangement and thermal configuration of an Alfa Laval gasketed plate heat exchanger.

When requesting spare parts, provide:

• Model

• Serial number

• Photograph of the nameplate

• Plate material

• Gasket material

• Number of plates

• Process-fluid information

• Required quantity

• Plant location

Surya Sankara Trading can support enquiries for genuine Alfa Laval plates, gaskets and applicable service components. Compatibility and availability must be confirmed against the exact equipment identification.

Preventive Maintenance

Preventive maintenance can help identify developing problems before they result in leakage, loss of performance or an unplanned shutdown.

A maintenance plan may consider:

• Operating hours

• Process-fluid characteristics

• Fouling tendency

• Temperature and pressure cycles

• Gasket age and material

• Cleaning frequency

• Previous leakage history

• Criticality of the equipment

• Availability of spare plates and gaskets

• Planned plant shutdowns

There is no single service interval suitable for every plate heat exchanger. Maintenance frequency should reflect the application, operating history and manufacturer’s recommendations.

Frequently Asked Questions

What does a gasketed plate heat exchanger service include?

The scope may include inspection, cleaning, regasketing, plate assessment, leak investigation, spare-parts identification and performance troubleshooting. The final work depends on the condition of the unit.

When should a plate heat exchanger be serviced?

Service should be considered when performance declines, pressure drop increases, leakage appears or gaskets show deterioration. Maintenance intervals depend on the application and operating history.

What causes a gasketed plate heat exchanger to leak?

Possible causes include aged gaskets, incorrect gasket material, displaced gaskets, excessive pressure, thermal cycling, incorrect tightening, plate damage or corrosion.

Can a leaking heat exchanger be stopped by tightening it?

Minor leakage may sometimes relate to plate-pack compression, but uncontrolled tightening can damage the equipment. Check the specified tightening dimension and investigate the cause before making adjustments.

How are plate heat exchanger plates cleaned?

Plates may be cleaned through a compatible cleaning-in-place procedure or after dismantling. The method must suit the deposit, plate alloy and gasket material.

When should heat exchanger gaskets be replaced?

Replacement may be required when gaskets become hard, cracked, swollen, displaced or unable to maintain sealing. Their life depends on fluid compatibility, temperature and operating conditions.

Can individual damaged plates be replaced?

In many gasketed models, individual plates can be replaced. The replacement plate must have the correct material, pattern, thickness, connection arrangement and position within the plate pack.

How can internal leakage be detected?

Signs may include contamination between circuits, unexplained level changes or altered product quality. Appropriate pressure or leak testing may be required to identify the affected plate.

What causes high pressure drop?

Common causes include fouling, blocked channels, excessive flow, incorrect plate arrangement or changes in fluid viscosity. Actual measurements should be compared with the design conditions.

Can additional plates be added to increase capacity?

Some gasketed plate heat exchangers can accommodate additional plates, subject to frame capacity, connection size and thermal design. A technical review is necessary before modification.
