Energy Recovery at Sea

Air handling units on seagoing ships must have high-quality heat exchangers to provide fresh air without interruptions. Heatex air-to-air heat exchangers are the perfect choice for marine or coastal applications.

Challenges & Solutions in Marine Environments

Marine application requirements differ from standard commercial ventilation applications.

Due to movements, limited space, and risk of corrosion, air handling units on seagoing ships must be equipped with reinforced, compact, high-quality heat exchangers to provide fresh air without interruptions for long periods.

Challenges in marine environments:

  • Accelerating forces due to movements
  • Limited space availability for installation and maintenance
  • Increased corrosion

Heatex recommends configuring any heat recovery unit according to the special challenges met at sea.

Solutions include but are not limited to:

  • Strong or even reinforced frameworks
  • Compact and customizable product design
  • Corrosion-resistant parts and components

Both our plate and rotary heat exchangers are made of aluminum, with excellent properties such as efficient heat transfer capabilities and an extraordinarily long life span. In tests made according to ISO 9227, Heatex heat exchangers have proven to resist corrosion in salt spray tests for extensive periods.

Heatex offers numerous design variables and options for each product, enabling perfect fit and performance in every marine AHU.

Recommended Products & Options for Marine Applications

Heatex Plate Heat Exchangers

Heatex plate heat exchangers enable heat transfer and have less leakage than rotary heat exchangers.

Typical options in marine ventilation applications include:

  • Epoxy-coated heat transfer material
  • Lacquered plate edges
  • Corrosion protected framework
  • Different profiles for customized installation
Heatex Crossflow Heat Exchangers
rotary heat exchangers
Heatex Rotary Heat Exchangers

Heatex rotary heat exchangers enable humidity transfer and generally provide higher efficiency than plate heat exchangers.

Typical options in marine ventilation applications include:

  • Segmented (sectorized) wheel and casing (Model EQ & EV only)
  • Reinforced casing (additional crossbars and welding)
  • Stainless steel shaft and bearings (permanently lubricated and sealed)
  • Corrosion protected framework
  • Molecular sieve-coated aluminum matrix (EN AW 1200 H19)
  • Power belt
  • Inspection hatches
  • Approved motor options according to LRS, DNV, or GL (IP class 54)
