Flagship FM48CW 48000 BTU 230V Marine Water Chiller

The smallest chiller in Flagship’s water-cooled lineup, the FM48CW delivers 48,000 BTU for boats making their first step up from split systems into centralized chiller cooling. This entry level marine water chiller shares the same compact 25″ x 15.5″ x 23″ chassis as the FM60CW, just tuned for a smaller cooling load.

Starting at this capacity tier makes sense for boats with two zones that want central-plant simplicity without paying for capacity they won’t use — and because it shares a chassis with the FM60CW, upgrading to more capacity later, if the boat’s needs grow, follows a known and predictable path within Flagship’s lineup.

Why Choose the Flagship FM48CW

Flagship’s published warranty terms cover the condenser, chassis, compressor, and evaporator for five years parts and one year labor, with controls, pump, and blower covered for one year parts and labor. As the smallest chiller in the lineup, this is the lowest-cost path into central-plant cooling for boats that have outgrown split systems.

What to Know Before Installing

• Confirm exact operating voltage directly with Flagship, since it isn’t specified on this particular listing
• This chiller requires separately specified air handlers distributed to each independent zone — it is not a complete system on its own
• Ships via freight; confirm actual weight with Flagship or CTM given the discrepancy noted above
• Professional installation and electrical planning is strongly recommended
