VARIABLE-FREQUENCY PERFORMANCE
Power, precisely
controlled.
Different cabins. Changing weather. A cooling load that never stands still. The VFD Series varies compressor speed to follow the vessel’s demand, delivering the output needed as conditions change.
Controlled acceleration minimises the startup surge associated with fixed-speed compressors. Once running, variable output supports stable chilled-water temperatures and efficient operation at partial load.
Minimal startup surge
A controlled ramp-up reduces demand during starting.
Consistent comfort
Stable chilled-water temperatures support every cabin zone.
TITANIUM SEAWATER CONDENSER
Exceptional resistance.
Built for seawater.
Titanium at the point where the system meets the sea.
Chosen for its exceptional resistance to seawater corrosion, the titanium condenser is a defining feature of the VFD Series. It gives the seawater circuit a premium material foundation for long-term marine service.
Combined with marine-grade construction and vibration-isolated mounting, it reflects the same focus throughout the system: dependable performance in a demanding onboard environment.
Premium condenser material
Titanium coils deliver outstanding resistance to saltwater corrosion.
Designed for service
Accessible connections and electrical compartments support professional inspection and maintenance.
INTELLIGENT MULTI-CHILLER STAGING
One plant.
Every cabin considered.
A central chilled-water circuit supplies fan coils throughout the vessel, allowing local cabin controls to manage individual spaces. Cooling equipment stays centralised while comfort is delivered where it is needed.
Up to eight chillers can be staged together for larger installations. Automatic load sharing distributes demand between units, while multiple chillers provide a basis for system redundancy.
Designed to scale
Configure capacity around the vessel’s layout, occupancy and cooling demand.
Control with clarity
The colour touchscreen gives crew and engineers access to operating conditions, diagnostics and protective warnings.
