Why Intelligent Sea Water Cooling Now 4 Demands for efficiency
and savings have never been greater Reduce operating costs while
maintaining peak performance Comply with growing regulation and
pressure to reduce the carbon footprint Eliminate unplanned
downtime: Maintenance costs increase with downtime Colfax Fluid
Handling is listening and responding to ship owners and operators,
leveraging deep pump knowledge and Smart Technology to help them
deliver reliable, profitable vessel performance.
