Plate heat exchangers for power and energy

Closed-loop cooling, lube oil cooling and heat recovery all rely on plate heat exchangers that have to keep running between planned outages.

Overview

Keeping critical cooling circuits apart

On power and energy sites, plate heat exchangers commonly separate a clean closed cooling circuit from raw cooling water — river, bore, cooling-tower or seawater — and cool lubricating oil and auxiliary equipment.

Because maintenance usually has to fit into planned outages, the practical priorities are knowing each unit’s condition in advance, having the right gaskets and plates ready, and completing the work inside the outage window.

Applications

Common heat-transfer applications

01

Closed-loop cooling

Isolating clean equipment-cooling circuits from raw cooling water.

02

Lube oil cooling

Cooling lubricating and control oil for turbines, engines and compressors.

03

Engine jacket water

Cooling and heat recovery on gas and reciprocating engine sets.

04

Heat recovery

Transferring waste heat to heating or process circuits.

05

Auxiliary cooling

Pumps, compressors, transformers and other plant equipment.

Challenges

Operating challenges we plan for

  • Continuous operation with maintenance only in planned outages
  • Fouling and scaling from raw cooling water
  • Chloride-bearing water that needs suitable plate materials
  • Critical units where a failure affects output
  • Units of different makes across one site

Maintenance

Maintenance considerations

Things to plan for on power and energy sites:

  • Inspect units before the outage so parts can be ordered in time
  • Hold gasket sets for critical coolers
  • Check plate materials against the cooling-water quality
  • Trend approach temperature and pressure drop to catch fouling early

FAQ

Common questions

Can you work to an outage schedule?

Yes. Tell us the outage dates and the units involved, and we’ll plan inspection, parts and servicing around them.

What if our cooling water is seawater or brackish?

Chloride-bearing water usually calls for titanium or another resistant plate material. Send us the unit details and water type and we’ll advise.
