Why Intelligent Sea Water Cooling Now
• 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.
