Marine Heat Exchangers For Ship Ventilation & HVAC Systems | VRCOOLER Marine AHU Cooling & Heat Recovery Coils
VRCOOLER, a professional China-based marine heat exchanger exporter, supplies full series of marine-grade heat exchangers exclusively designed for ship ventilation, air handling units (AHU), cabin HVAC and heat recovery ventilation systems. Vessel ventilation systems face harsh marine challenges including constant salt fog, high humidity, hull vibration, limited engine room space and fluctuating tropical/cold sea temperatures. Our ventilation heat exchangers solve temperature control, moisture removal and energy recovery demands for all vessel types, from container ships, bulk carriers, tankers to offshore platforms, superyachts and harbor tugboats.
All marine ventilation heat exchangers undertake three critical tasks to guarantee crew comfort and equipment safety:
Cool & dehumidify incoming fresh air in hot tropical waters, eliminate cabin condensation and mildew
Preheat cold outdoor air in frigid sea routes, reduce boiler power consumption
Recover waste heat from exhaust air, cut cooling/heating load and lower vessel carbon emissions to comply with IMO CII energy efficiency standards
Stabilize air temperature & humidity for wheelhouse, galley, mess room, accommodation cabins and electrical control compartments
Four Main Types of VRCOOLER Ship Ventilation Heat Exchangers
1. Chilled Water Cooling Coil (AHU Evaporator Coil)
The core cooling component inside marine air handling units, circulated with chilled fresh water from vessel central AC plant.
Structure: Copper tubes + aluminum fin bundle; optional epoxy anti-corrosion coating for salt mist resistance
Working logic: Hot humid outside air flows over cold coil surface, heat exchange removes heat and condenses excess moisture
Matching scene: All ocean-going vessel accommodation ventilation, wheelhouse air conditioning, offshore platform living quarter AHU
Custom feature: Built-in stainless steel condensate drain tray to collect condensed water and prevent water dripping inside air ducts
2. Hot Water / Steam Heating Coil
Used for cold climate air preheating, powered by boiler steam or recovered jacket water waste heat.
Two medium options: low-temperature hot fresh water coil, high-temperature steam coil
Material upgrade: CuNi90/10 tubes for vessels with slightly corrosive cooling medium; 316L stainless steel frame
Advantage: Recycle waste heat from main engine jacket water to replace electric heaters, save auxiliary power consumption
3. Air-to-Air Plate Heat Recovery Exchanger (Static Heat Recovery Core)
Sensible heat recovery device for fresh air supply and cabin exhaust air heat exchange, no cross-contamination between two air streams.
Epoxy-coated aluminum plate stack, fully sealed air channel structure
No rotating moving parts, low maintenance, anti-vibration reinforced frame for ship sway
Heat recovery efficiency up to 60%, widely applied on medium & large cargo ships and passenger vessels
Ideal for vessels with strict air hygiene requirements (galley, medical room, crew dormitory)
4. Rotary Enthalpy Heat Exchanger (Heat Recovery Wheel)
High-efficiency total heat recovery solution, transfers both heat and moisture between supply & exhaust air.
Molecular sieve coated aluminum wheel matrix, balanced humidity control for tropical high-humidity sea areas
Segmented wheel design for easy partial replacement; stainless steel sealed anti-corrosion bearings
Higher energy saving rate than plate type, perfect for cruise ships, superyachts and offshore living platforms
Complete marine classification standard accessories (IP54 marine motor, inspection hatch)
Matching Vessel Application Range
Container ship, bulk carrier, oil & chemical tanker, LNG vessel, offshore FPSO & fixed platform, harbor tug, fishing vessel, passenger cruise ship, superyacht, inland river cargo barge.
As a full-line marine heat exchanger supplier, VRCOOLER also supplies charge air coolers, box coolers, lube oil coolers and jacket water heaters to form complete vessel cooling system supporting products.
