Gasket Plate Heat Exchanger Service

Preventative maintenance reduces the risk of unexpected breakdowns and increases machine reliability. Regular maintenance of your gasket plate heat exchanger is crucial for service life, safety, and operational readiness. Timely preventative maintenance of your plate heat exchangers and replacement of damaged gasketed plates are essential for the safe operation of your heat exchanger.

We can provide preventive maintenance, troubleshooting, replacement plate packs, gaskets, repairs, and upgrades to increase capacity and efficiency.

Need your gasketed plate heat exchanger serviced?

Even the highest-performing plate heat exchangers are subject to wear and tear. Regular monitoring and servicing of your plate heat exchangers will keep equipment running effectively for longer and avoid costly and disruptive unscheduled downtime.

We have you covered, from cleaning, gasket removal, and regasketing to design engineering and technical support. We utilize a ten-step plate heat exchanger service process, which leaves nothing to chance, including inspections, replacing old gaskets, cleaning, and dye testing to ensure the best-in-class results every time.

Our field service crews are available at any time to restore your plate heat exchangers back to nameplate conditions. Quick, reliable, technical support and availability of spare parts are key elements of Separator Spares & Equipment’s After Sales and Service Program.

How to reduce clogging of gasket plate heat exchanger?

Reducing clogging can be done by installing a backflushing system or by using filters.


Installing a backflushing arrangement in the existing piping can be done relatively easily. Installing a backflushing arrangement is an easy and effective way to keep your system clean. Backflushing has the effect that major particles are flushed backward and out of the cooling system. Smaller particles will pass through the gasket plate heat exchanger, whereas larger particles will clog in the inlet section of the plate.


Filters will supplement the standard strainers installed on the suction side or the seawater pumps. You can install an automatic filter after the seawater pumps before the gasket plate heat exchanger.

What are the parts of gasketed plate heat exchanger?


In a gasketed plate heat exchanger, the plates are fitted with gaskets that seal the channels and direct the fluids into alternate channels. The plate pack is assembled between a frame plate and a pressure plate, and compressed by tightening bolts fitted between these plates. The channel plates and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to the support column. The physical design of the gasketed plate heat exchanger allows easy cleaning, and modification of capacity by the addition or removal of plates.

Need a replacement plate pack?

What is the expected lifetime of heat exchanger gasket?

Gasketed-Plate-Heat-ExchangerThe gaskets in all types of plate heat exchangers lose their elasticity after some years of continuous use. The expected lifetime depends on the operational conditions (temperature, pressure) and how often the units are opened.

For a central cooler, installed on an ocean-going vessel, a lifetime of 8-12 years can be expected. A lubricating oil cooler installed in a central cooling system (freshwater cooled) may also be around 8-10 years.

If the unit is installed in a conventional cooling system, meaning that the plate heat exchanger needs to be opened for cleaning more often, a lifetime of 5-8 years may be expected.

For applications operating with steam (tank cleaning heaters and dumping condensers) lifetime may be from 2-5 years due to the high temperature.
