Equipment
Charge air cooling
Alfa Laval charge air coolers for marine and industrial engines, cooling intake air after the turbocharger, with aluminium or copper fins and integrated housings tailored to the engine.
Equipment
Fernstrum® GRIDCOOLER® Keel Cooler
Factory-assembled 90/10 copper-nickel keel cooler with a one-piece brazed header, 56% silver-brazed joints and Fernstrum's exclusive enhanced-interior tubing — the long-established choice of naval architects for closed-circuit engine cooling.
System / Package
Heating and cooling for methanol
Alfa Laval heat exchangers for heating and cooling methanol fuel on board: semi-welded plate heat exchangers, AlfaNovaM all-stainless units and CBM copper-brazed units (-196°C to 225°C, 51 bar).
Equipment
Heating and cooling in the engine room
Alfa Laval gasketed plate heat exchangers for engine-room central cooling systems, with titanium central coolers on seawater and excess jacket water heat usable for AQUA Blue freshwater generation.
Equipment
OMEGA Clamp-On Laser Plate Heat Exchangers
Laser-plate jackets that clamp onto existing tanks and vessels to add heating or cooling — usually no welding on the tank and far cheaper than a new jacketed tank.
Equipment
OMEGA Laser Plate™
Laser-welded pillow plate (immersion plate) heat exchangers in stainless steel, duplex, nickel alloys or titanium — custom-built for cargo hold and tank heating, heat recovery and de-icing on ships and offshore units; supplied by R.W. Fernstrum with Omega Thermo Products.
System / Package
OMEGA Reinforced Laser Plate Banks for Cargo Hold Heating
Structurally reinforced stainless laser-plate heat-exchanger banks that replace failing pipe coils in barge and tanker cargo holds — built to survive sloshing loads in part-filled tanks while heating crude oil, caustic soda and other cargoes.
Equipment
OMEGA Suction & Bayonet Heaters
Flange-mounted laser-plate heaters inserted through the tank side: bayonet heaters for energy- and water-saving tank heating, and shrouded suction heaters that warm viscous cargo or fuel right at the pump suction.
Equipment
Stacked GRIDCOOLER® Keel Cooler
Two-tier (stacked or double-stacked) copper-nickel keel cooler that delivers more heat rejection in a smaller hull footprint — ideal for large engines and repowers.
Equipment
WEKA Boxcooler™
Uncoated 90/10 copper-nickel boxcooler mounted inside a sea chest — closed-circuit cooling for engines up to 10,000 kW with in-hull protection from ice, debris and grounding; built in the USA by R.W. Fernstrum under licence from WEKA Marine.
System / Package
WEKA Guard & WEKA Protector Type T – Boxcooler Protection System
Protection units exclusive to WEKA copper-nickel boxcoolers: the Guard shields the cooler from welding currents during construction; the Protector Type T guards against ICCP and stray currents in service and keeps the natural anti-fouling layer active — no ICAF needed.
Equipment
GRIDCOOLER® Keel Cooler – 5000 Series Aluminum
TIG-welded 5000-series aluminium keel cooler designed for unpainted aluminium hulls in fresh or cold seawater — alloy-matched to the hull to prevent galvanic pitting.
