Why it matters
Key Benefits
Efficient Auxiliary Cooling
Thermal performance monitoring ensures plate heat exchangers in auxiliary cooling service (lube oil, generator hydrogen, and closed cooling water systems) maintain the heat rejection capacity that equipment protection requires.
Compact Heat Transfer for Retrofit Applications
PHE installations in retrofit applications where shell-and-tube exchangers would not fit provide the compact heat transfer solution that plant upgrades and efficiency improvements demand.
Reduced Maintenance Downtime
Quick-access plate cleaning and inspection during short planned outages minimizes the maintenance time required to restore full thermal performance compared to the tube-side access constraints of shell-and-tube designs.
Context
Challenge & Approach
The Reliability Challenge
Power plant plate exchangers on lube oil cooling service face gasket degradation from oil exposure and thermal cycling that causes external leaks near turbine pedestals. Fouling from circulating water contaminants in open cooling circuits reduces heat transfer and increases lube oil temperatures above bearing protection thresholds. Sample cooler fouling causes sample temperature exceedances that affect the accuracy of online chemistry analyzers critical to boiler water treatment decisions. Gasket blow-out during pressure transients releases oil or cooling water near high-temperature turbine equipment. Plate corrosion from cooling water chemistry issues leads to pinhole leaks and fluid cross-contamination.
Our Approach
We perform thermal performance testing to quantify fouling severity on each plate exchanger application. Pressure-decay testing detects internal and external gasket failures. We evaluate gasket material compatibility with operating fluids and temperature ranges. Plate surface inspection during planned disassembly identifies corrosion mechanisms. Cooling water chemistry impact on plate and gasket materials is assessed. Our deliverable includes a gasket replacement schedule, fouling trend analysis, plate condition report, and a thermal performance monitoring program that prioritizes exchangers by their impact on turbine bearing protection, sample accuracy, and unit generation reliability.

Learn More →Plate heat exchangers serve auxiliary cooling applications including lube oil cooling for turbine and generator bearings, generator air or hydrogen cooler water circuits, closed cooling water system heat rejection to plant service water, and sample cooler applications. They are increasingly used in efficiency improvement retrofits where additional heat recovery or cooling capacity is needed in limited space.
PHEs offer two to five times greater heat transfer area per unit volume compared to shell-and-tube exchangers. This compact size enables installation of additional heat transfer capacity in existing buildings and on existing pipe racks without major structural modifications. The ability to add plates to an existing frame provides capacity expansion flexibility. Close temperature approaches achievable with counter-current PHE design enable heat recovery applications that shell-and-tube geometry cannot achieve efficiently.
Routine maintenance includes gasket condition inspection and replacement based on thermal cycling exposure, plate cleaning to remove fouling deposits (scale, biological growth, or particulate), and pressure testing to verify gasket and plate integrity. PHE maintenance is typically faster than shell-and-tube because the plate pack can be opened and individual plates cleaned or replaced without cutting piping. Gasket inventory management is important because gasket materials have shelf life limitations.
