Central cooling
Separate seawater and freshwater to protect engines and auxiliary equipment.
MARINE & OFFSHORE
Serviceable cooling for limited engine-room space.
Plate heat exchangers support central cooling, jacket-water and lubricating-oil circuits, separating seawater from freshwater in limited engine-room space while remaining accessible for service.
Duty-based selectionFluid & materialService access
01 · WHERE IT WORKS
Where the industry uses plate heat exchangers
Jacket-water cooling
Control engine cooling-water temperature as load changes.
Lubricating-oil cooling
Remove heat from engine, gearbox or hydraulic-oil circuits.
Auxiliary heat recovery
Use available waste heat for shipboard services.
02 · EQUIPMENT DIRECTION
How CHENHE equipment helps
Gasketed plate heat exchanger
Opens for cleaning and supports plate or gasket replacement during planned service.
Titanium seawater side
Improves resistance to chloride corrosion in seawater duties.
Duty-matched gasket
Selected for oil, temperature and maintenance interval.
03 · SELECTION NOTES
Confirm fluid and material together
Common considerations only; final selection is duty-specific.
SeawaterTitanium commonly considered
Fresh cooling water316L or project material
Lubricating / hydraulic oil316L + NBR/HNBR compatible gasket
High-temperature waterTemperature-matched plate and EPDM
04 · MARINE DESIGN CHECKS
Balance seawater resistance, pressure drop and onboard service
Marine selection must cover more than heat duty: limited space, continuous operation and planned service all matter.
Seawater quality and fouling
Confirm salinity, chloride level, strainer arrangement and access for backflushing or manual cleaning.
Thermal and hydraulic duty
Check inlet and outlet temperatures, heat load, flow rate and allowable pressure drop at design conditions.
Mechanical design
Confirm design pressure, design temperature, connection standard, available footprint and service clearance.
Onboard maintenance plan
Define plate and gasket spares, cleaning interval, redundancy needs and any class or survey documentation.
05 · DATA FOR SELECTION
Provide these details for an accurate marine selection
If the data is incomplete, send what is available and CHENHE will help identify the missing conditions.
