Marine

Seawater-resistant materials and compact designs for shipboard and port applications.

Use cases

  • Engine and lube-oil cooling
  • Central freshwater cooling
  • Seawater intake heat exchange
  • Ballast and HVAC service

Typical operating conditions

  • Process media: seawater, freshwater, lube oil, jacket water, HVAC glycol
  • Temperature range: -10 to 130 °C
  • Design pressure: typically 6–16 barg
  • Compact footprint for engine room and machinery space installation

Common engineering challenges

  • Seawater chloride corrosion and biofouling
  • Vibration and thermal cycling in engine-room duty
  • Space and weight constraints on board
  • Class society approvals (CCS, ABS, DNV, LR, BV, RINA, NK, KR)

Recommended materials & construction

  • Titanium Gr.1 plates for seawater service
  • AISI 316L / 254 SMO for freshwater and mixed duties
  • Cupro-nickel 90/10 or 70/30 tubes for shell & tube seawater coolers
  • NBR / HNBR gaskets for oil-side service

Typical delivery scope

  • Class-society-approved drawings and materials on request
  • Compact frame sized to engine room footprint
  • Full documentation for shipyard integration
  • Spare plates and gaskets set for onboard service

Ranges shown are indicative for this industry. Actual design is confirmed per project against your duty sheet.
